Create a Reservation from Shopping Cart (Extended Classic Scenario)

Landscape :

SRM 7.02 / ECC 6.06 – Extended Classic Scenario.

1. Go to SPRO -> SRM Server -> Cross – Application Basic Settings -> Define Objects in Backend System
2. Fill the table with Purchasing Group, Product Category, Backend and the action that should perform the system, at this point we have three options :
   • Always Reservations form material types subject to inventory management.
   • Reservation generated if stock available. /Otherwise External Procurement.
   • Always External Procurement
3. Choose the options according to your business requirements and save.
4. At SRM Server, Implement BADI BBP_EXTLOCALPO_BADI Method DETERMINE_EXTPO in order to start working in Classic Scenario. This Badi is used to switch between Classic and Extended Classic scenario in runtime, the Badi allways assume Classic until BBP_EXTPO_GL-BBPEXPO = ‘X’.
5. At SRM Server, Implement Badi BBP_TARGET_OBJTYPE Method DETERMINE_TARGET_OBJECT_TYPES and according to your business requirement write the code to choose when to create a Reservation, Purchase Requisition or Purchase Order as follow-on document, To indicate with document will be created in Backend use the field CT_ITEM-PACK_OBJTYPE and assign the BUS value corresponding to the document you want to create, in case of reservation , pack_objtype   = ‘BUS2093’.
6. At Backend Server, you must create number range for reservation or any other document you want to crate. In ase of reservation I will use RB.
7. At SRM Server, Assign Number Range to document type in SPRO->SRM Server-> Number Ranges

Hope this help!

Thank you !
