Auto Accounting - Null Code Combination for Project Invoice

 Hi,

I have set Auto Accounting rules.

I ran PRC: Interface Draft Invoice to Receivables.

Invoice got transferred to Receivable Interface.

When i run Auto Invoice Import Program I am getting following error for receivable and revenue account.

The code combination id is null.

Errors:   1) You must supply an unique id for your XXX Accounting Flex ((Nil))

In Invoice Transaction source in Accounting Information Tab Accounting Flexfield is set to Segment.

Even if i set it to ID it gets reject

How do i import invoice ?
