Revision Level在PS中的决定

何为Revision Level: 

You can identify material or document changes that are made with reference to a change number by the use of revision levels. 
When you want to process the BOMs for these materials or documents at a later date, you can find and call them using either the change number or the revision level.

先看配置.CJ12中,物料100-100的Revision Level是这么配置的.

当物料在项目中分配时, FM REVISION_LEVEL_SELECT会被读到. 可以看出, 输入后, Revision Level是由CAUFV-AUFLD决定的, 即Date of BOM Explosion/Routing Transfer. 这里是Network创建日期.故输出的RESBD-REVLV = B

Include LCOMDFM1

Form   MATERIAL_CHK

FM       REVISION_LEVEL_SELECT

RESB表 最后一项09

SAP提供BADI REV_SELECT, Method SELECT_INDIVIDUAL进行用户自定义
