REG : Forwarding Work Item to another Operational Purchaser

Hi Gurus,

I have a requirement, where when an approver receives a work-item, he should be able to forward the same to another Operational Purchaser within the same Purchasing Group (For example in a scenario where Shopping Cart line Item was assigned to Head of Purchasing Group or in a scenario where Workload re-distribution is required).

When Work item is forwarded, I need to implement a validation to ensure Work item is being forwarded to Buyer belonging to same Purchasing Group.

FORWARD_WI attribute is also set to 'X' in PPOMA_BBP for the buyers.

  Note: In Standard SRM, Work item may be forwarded to any valid user id without any check.

I am not getting the logic for the same, Please guide me with the sample code on the same.

Thanks,

Aakash Awasthi
