Material issue from Technician Portal is struck in MTL_TRANSACTIONS_INTERFACE

Hi
We are in 12.1.3 and use Technician Portal for the repair .
We perform Material issue transactions for the Repair components .
Noticed that all these transactions from Repair technician portal are struck in the MTL_TRANSACTIONS_INTERFACE and shows in pending transactions form.


select *  from MTL_TRANSACTIONS_INTERFACE where source_code ='WIP Issue'

Process_flag,Transaction_mode,Lock_flag
1                         1                                1


THIS SEEMS TO BE THE PROBLEM.


The transaction manager would pick up only when the   TRANSACTION_MODE of 3, LOCK_FLAG of ’2′, and PROCESS_FLAG of ’1′  and assigned to a Transaction Worker.

Is it a known bug or somesetup issue?

Please advise?
