Reproducing the Issue

  1. Go to General Ledger work center.
  2. Go to Source Documents view.
  3. You find that Goods and Activity Confirmation XYZ has an error 'Locking the objects not possible; objects locked by AAA'.


When you create a lot of Point-of-Sales transactions, there would be some time required for the postings, sometimes a temporary lock issue will occur.


The system will retry and resolve the temporary lock issue itself. After that all transactions will be posted completely. There is no dead lock in the system. The end user can try calling the service in smaller chunks to improve the performance. Please call the service like 100 line items at once then a smaller chunk later. Also, please try to schedule the web service on non-productive hours to have a better performance.
