Calling API mtl_online_transaction_pub.process_online from Trigger

Question

Hello Gurus,
I'm inserting rows into mtl_transaction_interface table and calling mtl_online_transaction_pub.process_online to process it from a TRIGGER on mtl_material_transactions table.
But it doesn't process the data and errors with process_flag 3.
If I comment the call to mtl_online_transaction_pub.process_online and just insert into interface table and then call mtl_online_transaction_pub.process_online from independent PLSQL block it works fine.
Can someone suggest a solution for the problem, I think the issue is in the design.
Thanks
Manu

Hi,
I hope you are using an 'after insert' trigger on mtl_transactions_interface.
Ensure that the MTI record is populated with transaction_header_id with transaction_mode = 1 (Online), process_flag = 1 and lock_flag = 2.
Call the txn processor with transaction_header_id, and it should work.
If transaction_mode is 2 (immediate) or 3 (Background) then the MTI record must be commited in database; calling txn processor from trigger cannot see the record as it is not committed.
If it doesn't work, then you will have to retrieve errors from the return message to understand the problem in detail.
I would strongly recommend not to use trigger for such processing.
I believe, you have a custom package/procedure from which you are inserting data into MTI.
once the insert is done, then you can call the same API from custom code.
Also check how exactly is MTI is getting inserted, is apps context set correctly (either by means of concurrent program, or by explicitly calling fnd_global.apps_initialize(..) )
If it still doesnt work, enable Inventory Debug by setting up profiles INV%DEBUG%, and see the log messages. (e.g. set the log file as /usr/tmp/mti.log )
Hope it helps,
