• Message number: 124

• Message text: Document type will be changed: Check (-> long text)

What causes this issue?

A different document type is used for further processing. The reason
for this may be the switch from an invoice to a credit memo (or vice
versa), or a manual change.

System Response

The system issues a warning if this results in controlling parameters
being changed for further document entry.
An error message is issued if there is a collision with cross-company
postings.

How to fix this error?

Check whether changing the document type also changes dependent values.
These could be the exchange rate for a posting in foreign currency, the
indicator for negative postings, or deriving or entering a trading
partner. If there are already several trading partners in the document,
it is possible that the processing can only be continued after all of
the data entered has been reset. You have to start the transaction
again to do this. If the cross-company entry is not permitted in the
new document type, the entry is terminated.

Procedure for System Administrators

The system issues an error message and will not allow you to continue with this transaction until the error is resolved.
