1、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 are the following firming types: 0procurement proposals are not firmed automatically. no firming takes place with this firming

2、 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 planning 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

6、te on the initial screen of the planning run and in the stock/requirements list in mrp and in long-term planning.需求時(shí)界需求時(shí)界（dtf，demand time fence）是在mps/mrp計(jì)劃期間的一個(gè)時(shí)間點(diǎn)，設(shè)定于目前日期與計(jì)劃時(shí)界（ptf，planning time fence）之間。在目前日期到dtf之間，包含確認(rèn)的客戶訂單。在此期間內(nèi)，除了經(jīng)過仔細(xì)分析和上級(jí)核準(zhǔn)修改外，不能修改生產(chǎn)計(jì)劃。計(jì)劃時(shí)界計(jì)劃時(shí)界（ptf，planning time fence）介于需求時(shí)界和計(jì)劃

7、期間的最后日期之間，在需求時(shí)界和計(jì)劃時(shí)界之間包含了實(shí)際以及預(yù)測的訂貨，而在計(jì)劃時(shí)界之后則只后預(yù)測的客戶訂單。需求時(shí)界:所謂界就是界線的意思,所謂需求就是需要意思,總的來講需求時(shí)界就是總裝提前期段的時(shí)間(總裝提前期:從產(chǎn)品研發(fā)-采購-品檢-加工-生產(chǎn)-入庫-出貨)也就是正式下訂單的總裝提前期時(shí)間計(jì)劃時(shí)界:所謂界就是界線的意思,所謂計(jì)劃就是將來的意思,總的來講計(jì)劃時(shí)界就是累計(jì)提前期段的時(shí)間(累計(jì)提前期:就是總裝提前期+采購+加工時(shí)間)也就是預(yù)計(jì)訂單或者合同訂單計(jì)劃的時(shí)間cross-plant planningpurposedemand management can also be used to

8、plan across plants. for each material, there is a planning plant that procures and stores the materials independently of orders. there are also one or more ordering plants in which the materials are used for sales orders, production orders, or for other requirements.prerequisitesyou must set up the
