Inter Company Transactions Error

Dear Experts,

While posting an inter Company transaction, the following error is confronted with:

A unique company code has not been assigned to company number XXXXXX

Message no. GLT0001

Diagnosis

Document breakdown is active in your system. In certain cases, a company code is derived from the company ID number, and this must lead to the assignment of a unique company code.

A unique company code could not be assigned to company number XXXXXX.

System Response

You cannot carry out the required posting.

Procedure

Assign one company code to company number XXXXXX.

We are working on ECC 6 and New GL is activated. Both the Company codes considered in the transaction have been assigned to the same Company. The required setting is maintained in OBYA. Also the Inter Company postings is ticked in the document type used.

Kindly let me know what is the gap for this error.

Best Regards,

Srini
