Hi YC,
It this issue occurs with item update only or its happening for other masters also?
Anyways,if replications are working from one company to other and issues exist with other half of cycle, then I suspect something is wrong with your integration environment.
You may use the following approaches to debug the source of contention:
1. Check if Event Sender is configured accurately for each of the Intercompany participating companies.
2. Stop SAP event sender service and generate an update event in the company.
Check SEVT table, if any integration event has been generated.
3. If events exists then you may start the Event sender service and check for the event in Integration Framework-->Control Center--> Event Monitor.
4. If event also exists there, then you may check Intercompany Message Log, to check the status of update event.
I hope these steps shall help you identify the misconfigured element in your Integration setup.
Please Note: You are requested to execute these steps only on Test environment.
