SAP Note 18614 - MMIM: Transaction/event type for goods movements

Symptom:

The transaction/event type (field: T158-VGART) for goods movements is set in table T158 for the transaction code. This transaction/event type cannot be set via Customizing.

Cause and prerequisites

The transaction/event type has a program control function. If the customer sets the transaction/event type, this may lead to errors. For this reason, the setting should not be possible via Customizing.

Solution
Please do not change the transaction/event type in table T158. You should look for alternatives to reach your aim without making any changes.
