How To Fix CNVA_20290_CHECK098 - The same G/L account number exits in more than one company code

CNVA_20290_CHECK098 - Overview

• Message type: E = Error

• Message class: CNVA_20290_CHECK - Message class for company code merge preanalysis

• Message number: 098

• Message text: The same G/L account number exits in more than one company code

The same G/L account number is assigned to more than one house bank
account ID in company codes that will be merged (see table T012K 'House
bank accounts'). The account with the same number would consequently
also be merged. It may be necessary to make a transfer posting for one
(or several) of the G/L accounts that are now in different company
codes, but would no longer be so after the merge.
If identical G/L account assignments to a house bank account IDs were
already in the same company code before the conversion, this was either
intended or an error, and the company code merge will not have any
influence on the given situation (by default).
