1、.MRP Master Data Parameters1MRP Typen MRP procedureIndicator that specifies the procedure with which the material is plannedn Firming Type of the Planning ResultFor the planning run, the firming type determines how procurement proposals are firmed and scheduled within the planning time fence. There

2、are the following firming types:· 0Procurement proposals are not firmed automatically. No firming takes place with this firming type.· 1Procurement proposals within the planning time fence are firmed automatically as soon as their date is at least one day before the end date of the plannin

3、g time fence. The date of new procurement proposals created in the planning time fence is moved to the end date of the planning time fence. As a result, these new procurement proposals are not firmed.· 2Procurement proposals within the planning time fence are firmed automatically as soon as the

4、ir date is at least one day before the end date of the planning time fence. No new procurement proposals are created automatically within the planning time fence; that is, the shortage situation is not adjusted within the planning time fence.· 3Procurement proposals within the planning time fen

6、g time fence.DependenciesIf you enter a manual firming date, the planning time fence is extended to this date automatically.You can enter a manual firming date on the initial screen of the planning run and in the stock/requirements list in MRP and in long-term planning.l Manual firming dateDefinitio

7、nYou can select any date for the manual firming date. If a planning time fence has been created for a material then the following applies:If the manual firming date lies before the end of the planning time fence, the planning time fence is still valid.If the manual firming date lies after the end of

8、 the planning time fence, the planning time fence is extended until this date.Setting the manual firming date instructs the system to firm all order proposals (planned orders, purchase requisitions, scheduling plans) for the planning run with order finish dates before this date, if the materials hav

9、e an MRP type which contains no firming type or firming type 1 or 2.The system does not automatically firm order proposals for materials that have an MRP type with firming type 3 or 4, even if their order finish dates lie before the manual firming date.Materials with an MRP type without a firming ty

10、pe are treated as materials with firming type 1 in relation to the manual firming date.UseYou can use the manual firming date in MRP and long-term planning.DependenciesAll planned orders, purchase requisitions and delivery schedules in MRP that have not been firmed are affected.In long-term planning

11、, only planned orders that have not been firmed are affected.If you copy firm planned orders from long-term planning to operative planning, the system proposes the manual firming date as the end of the period for copying.n Indicator: delete firm planned ordersCauses firm planned orders before the ro

12、ll forward period to be deleted in the planning run, and new planned orders to be created in accordance with the new requirements situation (or, with the corresponding firming type, to be moved to the end of the planning time fence). UseIn roll forward planning, this makes it possible to define that

13、 the master production schedule is updated in a specific period. DependenciesThe roll forward period is defined in Customizing for Materials Requirements Planning in Define Planning Time Fence and Roll Forward Period.n aIndicator: plan material regularlyIndicator determines that materials with this

14、MRP type are to be included in planning in regular intervals, even if this material has not undergone a change relevant to MRP.n Forecast indicatorIndicator that specifies whether the forecast results should be used in materials planningn Consumption indicator of forecastSays which consumption value

15、s are relevant for the forecast, total consumption or unplanned consumptionn MRP indicator of forecastYou use this indicator to define whether forecast values are considered in the net requirements calculation.If they are to be considered, define whether as a· total requirement or· unplann

16、ed requirementn Reduce forecast requirementsThis indicator controls how the forecast requirements are to be reduced.The reduction of the forecast requirements can be carried out in three ways:· Reduction of forecast requirements by consumptionIf consumption exceeds the forecast requirements of

17、the current month, the system will also reduce future forecast requirements · Reduction of forecast requirements exclusively in current monthIf consumption exceeds the forecast requirements of the current month, the system will only reduce the forecast requirements in the current month.· A

18、verage reduction of the forecast requirementsIn this case, the reduction of the forecast requirements is based on average daily requirements. Actual consumption is not relevant for this particular setting.Here, the system first calculates the average daily requirements:Forecast requirements/number o

19、f workdays of the forecast periodThe forecast requirement is then reduced by the amount resulting from the following formula:Number of workdays x average daily requirementsn Indicator: calculate safety stockThe indicator specifies whether or not the system calculates the safety stock automaticallyn

20、Indicator: calculate reorder levelThe indicator specifies whether the system should calculate the reorder point automatically.n Screen sequence for the header detailsKey which identifies the screen sequence for the display of the header details in the evaluation of the planning run.n Method by which

21、 a material is plannedThis indicator can be used to identify materials that are planned by an external system. The indicator does not influence MRP. If standard MRP is not used to plan materials with this MRP type, a corresponding MRP procedure, for example N, must be maintained2MRP Areasn Type of M

22、RP areaThe key defines whether the MRP area corresponds to a whole plant or to a storage location or to a subcontractor.ExampleYou want to specifically plan the components that are required on a particular assembly line. You therefore define an MRP area of the storage location type and assign the pr

23、oduction storage location to it, from which you are taking the components that are required on the assembly line.Dependencies· The MRP area of the type plant contains a whole plant. The system automatically creates the plant MRP area when converting the planning file entries.· The MRP area

24、 of the type storage location can contain one or several storage locations. You assign the storage location to the MRP area in the storage location fieldA storage location can, however, only be assigned to one MRP area.· With the subcontractor type the MRP area contains just one subcontractor/v

25、endor. This enables you to specifically plan the components to be provided for this subcontractor. You assign the subcontractor in the subcontractor field.A subcontractor, however, may only ever be assigned to one MRP area.3Reference plantUsing a reference plant means that in MRP, the system uses ce

26、rtain control parameters that are not maintained in the planning plant, but only in the reference plant. This reduces the amount of data to be maintained for the following parameters:· planning calendar (delivery cycle)· MRP cycle· range of coverage profile· rounding profile·

Planning strategies and requirements are linked via the requirements type.n Consumption indicatorControls the consumption of planned independent requirements with customer requirements whereb

29、y the requirements type is only allocated one consumption strategy.n Planning IndicatorThe planning indicator determines which of the following is valid for the planned independent requirement:· net requirements planning· gross requirements planning· individual requirements planning,

31、lanned independent requirements whereby the customer requirements type is only allocated one consumption strategy.n Requirements record not relevant to MRPThis indicator determines whether customer requirements are relevant for the planning run, that is, whether they are included in the net requirem

32、ents calculation:· customer requirements are relevant to the planning run· customer requirements are not relevant to the planning run, but are displayed· customer requirements are not relevant to the planning run and are not displayedn Account assignment categorySpecifies whether acco

33、unting for an item is to be effected via an auxiliary account (such as a cost center).UseThe account assignment category determines which account assignment data (such as cost center, account number and so on) is necessary for the item.n Settlement profileThis field contains the settlement profile.

34、You can copy the settlement profile into the settlement rule to change it, for orders from the order type, and WBS elements from the project profile.n Results Analysis KeyKey that defines the valuation of the order during period-end closing.UseHow the results analysis key is used depends on the natu

35、re of the order.· For orders with revenue (internal orders, sales orders, and projects), the results analysis key determines how results analysis is carried out.Results analysis is recommended in the following situations:o When you are using a nonvaluated sales order stock or nonvaluated projec

36、t stock and you want to valuate the inventories at the end of the periodo When you are using a valuated sales order stock or valuated project stock and want to valuate goods that have been delivered but not yet invoiced, or when you want to create reserves automatically · For orders without ref

37、erence to a sales order item or WBS element, the results analysis key determines how the work in process is calculated.The production type can be make-to-stock or mass production on the basis of sales orders. The work in process is calculated at the level of the production order, process order, or p

38、roduct cost collector.· For capital investment measures, the results analysis key determines how the system calculates the values to be capitalized.ExamplesFor orders with revenue, costs may be incurred before any revenue is received. If you are using a nonvaluated sales order stock, results an

39、alysis enables you to report the costs as work in process. After the first revenue has been posted, you can calculate the cost of sales. If the calculated cost of sales is greater than the actual costs incurred to date, the system creates reserves for unrealized costs in the amount of the difference

40、.No revenue is posted in CO for orders without reference to a sales order item. Each goods receipt for these orders is valuated. The work in process for these orders can be calculated with two different methods:· Work in process at actual costsThe actual costs for production orders and process

41、orders for which no delivery has taken place are reported as work in process. After a partial delivery, the difference between the debit of the order with actual costs and the credit of the order from goods receipts is reported as work in process. When the order is complete, this work in process is

42、canceled. The difference between the debit and credit of the order is then interpreted by the system as a variance.In Product Cost by Order, the work in process is usually valuated at actual costs.A requirement for the valuation of work in process at actual costs is that the default rule PP1 (full s

43、ettlement) must be specified in the order.· Work in process at target costsA confirmation is made for each operation or at certain reporting points. The system uses the confirmations to determine the quantity of work in process. This quantity is valuated using the strategy sequence specified in

44、 the valuation variant for work in process and scrap.In Product Cost by Period, the work in process is always valuated at target costs.A requirement for the valuation of work in process at target costs is that the default rule PP2 (periodic settlement) must be specified in the order.See also: Check

45、default values for order typesDependenciesThe control parameters for results analysis, for the calculation of work in process, and for the calculation of the values to be capitalized are selected through the results analysis key in the order and a results analysis version. If you have not specified

46、a results analysis key in the order, the order will not be included in the calculation of work in process during period-end closing.The control parameters for the valuation of work in process in Product Cost by Period are defined in Customizing for Product Cost by Period.See also: Define valuation v

47、ariant for WIP and scrap (target costs) n SD availability checkYou must carry out an availability check for the corresponding transaction. If the indicator is not set and if the assignment of independent requirements planning is active, then an availability check is carried out against planned requi

48、rements for the material. If this assignment is not required, no check takes place.The type of check is proposed by the system. Each check can be switched off (but not on) by transaction in both sales and shipping.n Transfer of requirements / Begin assembly order from SDTransfer of requirements is t

Conversely, it can simply be left inactive at schedule line level, as long as it is not already activat

You set an indicator for maintaining the requirements class: In

51、this case you can still decide at schedule line level, whether or not you require transfer of requirments for the relevant transaction. n Requirements reduction indicatorIndicator specifies that the anonymous make-to-stock production is reduced by customer requirements which are planned as sale from

52、 stock.4.1.1.3 Assembly Ordern Assembly typeControls what type of assembly processing is carried out with which procurement element.There are two types of assembly processing· static assembly processing· dynamic assembly processingStatic assembly processingIf you create a sales order for a

53、 material with the 'assembly processing' technique, the system carries out an availability check for the components needed for the assembly and creates a single procurement element in the background.The procurement element is assigned to the sales order directly. The number of the procuremen

54、t element is determined in the sales order.Dynamic assembly orderIf you create a sales order for a material with the 'assembly processing' technique, the system carries out an availability check for the components needed for the assembly. Depending on the results of the availability check, e

55、ither one or several procurement elements are created. The quantity for a one-time delivery and/or the next possible deadline for a full delivery and/or a delivery proposal with then ext possible deadline are displayed on the availabililty control screen.During dynamic assembly processing, you can not change the quantities and deadlines. You can, however, select the 'fix date and quantity' field, if necessary. The 'check scope' and 'other plants' functions are not available here.
