Question

Dear Gurus,
To create new versions in Demand Management, is to go via SPRO path--> Production --> Production Planning --> Demand Management --> Define Version Numbers
There is another setting which want to understand.
SPRO path--> Production --> Production Planning --> Demand Management --> Allocate version and for auto spilitting to reference
What is reference we are talking about? From where is this reference for eg 1 - Reqm Plan has come from?
Is version maintained here is standard or you can change it?
If we can change which version is to be taken for each reference?

Answer 1

Hi Srini
The first sap path is to create version no which you can use to create PIR in demand management like version 01, 02, AA, AB.
The 2nd path is about splitting of demand management PIR into lower period say year to week, week to day during copy of version and here you assign one version number which will be used during copy.Reference is from where you are getting demand.
