Sourcing for External Requirements using CPPR & Traditional way
From EHP4/ERP 6.0 requirements can be transferred using Collective Processing of Purchase Requisition (CPPR) .In both ways we can handle custom checks like Purchase Group/Material Group validations.
As per Collective Processing of Purchase Requisition handling of Direct Material possible in SRM .Here creation of Purchase Order done in SRM system where deployment scenario is “Extended Classic” .
·
- External requirement transfer using CPPR can be access from portal
- Using BADI ME_REQ_SOURCING_CUST we can handle custom logic for additional validation .Parameters available on PR documents for Plants\Purchasing Group etc validations .
- Additionally we can check follow-on document from PR i.e. RFX or SC in sourcing cockpit
- PI is mandatory component to process XML messages for CPPR.

Amit
