Material Transaction Distribution - inventory Valuation *Code Combination is disable*

Hello Group,

I was wondering if you have seen a similar issue before. We have this Code Combination Account that is Disabled, but still, when I perform a WIP Completion, this Code Combination Account is being used. see Attached screen shot.

Would anyone know where this Inventory Valuation Account is coming from? Are they doing a Copy from an old Discrete Job?

Thanks a lot for your help, inputs, comments.

Regards,

Philip
