Sourcing Workflow

Hi,

We are in the process of implementing workflow from sourcing. I have few questions regarding this functionality. We have implemented BADI /SAPSRM/BD_WF_PROCESS_RESTART for normal workflow restart prior to sourcing, but the same is not triggered for SOCO workflow. We are in SRM 702.

1. Is there any BADI which we can implement to check if the price/quantity has been reduced or not?
2. We have header level approval and when item go to the SOCO, the buyer has the ability to change one line item and the WF does not triggered, has anyone come across this situation.

Please let me know.

Thanks,

Ashwin
