Code_combination_id for an item is not populating into RA_INTERFACE_DISTRIBUTIONS_ALL

Hi,

We're on R12.1.3 version of Oracle apps.

Issue: We have an item for which code combination id is not getting populated to RA_INTERFACE_DISTRIBUTIONS_ALL  hence the same cannot be imported to AR.

Autoinvoice Error:

You must supply an unique id for your XXCUS Accounting Flexfield~(Null)~162

Analysis:

Transaction source for accounting Flexfield is set to ID and neither CCID nor segments (1-30) in RA_INTERFACE_DISTRIBUTIONS_ALL are populated

Validated the item setup and has all the required attributes enabled and has the correct accounting assignments.

Please advise.

Thanks,

Ram
