I have to customize purchase process ( General Purchase, Subcontracting Purchase, and STO ) with assignment of sale order. Client going with completely MTO process and they want to track all stages of material with reference of Sale Order.
Here they are doing following process : -
1) After customer requirement they are doing sample process and after confirmation of sample they punch sales order and for that they purchase some materials with reference of that sale Order.
2) For some process they are sending some material for subcontracting process with reference of same sale order no.
3) For some process they are sending some material to different plants for same sale order no. (STO)
For tracking purpose every stage they are mentioning sale order no in legacy system and they want same thing in SAP.
Kindly suggest me the process with sale order assignment because as of my last experience i have not worked on this scenario.
Majorly subcontracting and STO process to map is critical for me with sale order assignment.
I have checked for subcontracting process with a/c "c" and item category "L" but they want to track the stock after doing the GRN. I have heard about one more process which are executed with a/c "M" and item category "L" and for issuing the material to subcontracting process with 311 "E" movement type and every time new storage location will created with vendor name. but i don't know exact process for same. If you have any document so kindly share with me it is very urgent requirement for me.
