Error in EA00 - EITR does not exist

Hi Experts,

I am tryign to Final bill a moved out contract for the dates 16.05.2007 to 31.12.2008.

The joint invoicing condition is 1. When I try to bill these billing documents through EA00 I am getting the Error "EITR <Billing Do. no.> A does not exist.

Even when I try to confirm move out and Final Bill through Transaction EC56E I am getting the same error for all 3 contracts.

The three billing documents for which I am getting the error have been already reversed and are not seen in EITR. They are seen in table ERCHC.

Any idea why this error occurs? I added entries in table EITR manually for the 3 billing documents, then the error does not occur any more. But this doesnt seem to be a very acceptable solution.

Let me know your insights on this one.

Thanks and Regards,

Prajakt Dhumal
