transfer purchase requisitions to SRM 5.5 from ECC 6.0
We have an issue with our program BBP_EXTREQ_TRANS to copy our pur requisitions to SRM 5.5 (setup as Extended Classic scenario) but it invertiblely gets jammed weekly without the ability to identify a root cause. The latest error we could find in SRM is that 'System status I1139 could not be set for shopping cart xxxxxxxxxx. Does anyone know what this error message is trying to tell us and how to solve this?
Background: the above program runs in batch every five minutes with demand coming from our PM module ie, work orders which generates the purchase requisition. It appears that the jam occurs on existing purchase orders and not new POs, when we make a change to the work order. We believe a level of validation done by SAP might be accountable for the errors, which might be legitimate. Have anyone faced this issue?
