Sender SOAP channel single threading/queue

[Harish]

Hi Experts,

I have a strange situation for which I do not unable to find the simple answer/solution.

Scenario - SAP post the invoice received from the client system and then client try to update the invoice (modify some attributes) via sync interface. The issue comes when they post multi-line invoice and try to update more than one line at a time (they have the batch process at there end so all the message trigger every 15 min).

Because the document is locked with the update on line 1 the second message fails with error document is locked.

Possible solution -

1. Update the SAP interface code (proxy code) to wait if lock is found

2. configure the interface to single threaded so only one message process at a time or queue one by one.

Please let me know if there is any way to single thread specific soap channel/ICO etc.

Thanks in Advance,

Harish
