Business Rules Framework (BRF) Implementation

Hi Gurus,

We are in SRM 7.0 (EHP2) ,Extended Classic and planning to migrate from Application Controlled workflow to Business Rules Framework( BRF) workflow.

As of now we have BBP_WFL_APPROV_BADI to determine approvers dynamically based on Approval limits custom table and based on cost center for SCs.

For POs its based on Purchasing Hierarchy

Please let me  know how to handle dynamic approvals for SC and PO.

Also please let me know how to handle the opens SCs and POs and their migration,switch back to application controlled if things doesn't work fine.

Thanks in advance

Raj
