SAP Error Message - Details

• Message type: E = Error

• Message class: GU - FI-SL utilities

• Message number: 063

• Message text: Conversion of MM activities: do not enter RMML, RMBA and RMBE in SL

What causes this issue?

The activites RMML, RMBA and RMBE are not transferred to GLX. They
have therefore been removed from the activity definition. If they were
already assigned to a ledger, this assignment is deleted.
Activity RMUM is new and must update the G/L account transaction
figures. It is used for revaluations in the activities RMWA, RMWE,
RMWF, RMWI or RMWL. The activity RMUM is now also assigned to all
ledgers to which at least one of these activities is assigned. If you
do not want this activity for a ledger, you must remove it from the
ledger afterwards in customizing.

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