Hi Rishav
Everything worked correctly through Validation testing. I have compared the partner config in dev and in the sandbox (used for the mock cutover). So far, I have found no differences. I checked the time stamps on the transports to confirm everthing imported to sandbox in the right order. Things look correct so far.
I reactivated the BRFplus and Approval rule policies. No sure I changed, but now the Sold To Party (not the Approver partner) is being updated with the Change Manager. There is no Access Sequence for the Sold To. The BRFplus rules populate the Sold To. The Change Manager is cleared after it is copied to the Sold To. I set a breakpoint in the BSP method that sets the Sold To partner, but it is not executed.
I'm still debugging but am very puzzled. Anyone have any thoughts on what else I should check?
