Choose item qty in expense subinventory in ODM Job Execution

Hi,

I need an advice for my problem.

I'm using Oracle EBS with Oracle Discrete Manufacturing.

I have Item A in my expense subinventory M ( with qty and without value )

I have item X as my assembly item.

I put item A inside the Bill of Material of Item X.

I cannot choose item A from my expense subinventory M when i do my job execution .

Do i have to do a setup to enable to choose item from expense subinventory in job execution?

Thanks

Regards
