I have some question about the work center when pick up by the creation of production order. When we create production order manually via CO01, SAP pick workcenter BSBA111 for this order. And when we convert a planned order to a production order SAP pick work center CAWORK01. same finished product is been consider with this material number 1111002 in plant 0012. why in different way of creating production order, but the system is been picking two different work center with different formula? please explain deeply for my concern.
In this case what is happening is that while creating manual Production order you are manually selecting the production version . therefore the routing assigned to that particular production version gets copied & subsequently the work centre assigned to th routing gets copied along with that.
Since you have used selection methood as 3 (selection only by production version) the system searches for the valid production version starting from the 1st production version in your list of production versions & stops as soon as it finds the valid one & selects it.(I.e. the 1st version which is valid for the date of exposion & within the lot size defined)
Now in this case the one which you selected & the one which the system finds during MRP can differ.
Thats why your work centres differ , because the production versions differ.
Therefore If you want the selection to be same in Manual PO & PO by MRP , in OPL8, for your plant & order type , select indicator 0 for Production version i.e. automatic selection of production version.
