Key fields are not together at the beginning of the view

Message no. MC705

Diagnosis

All the key fields of a maintenance view should be stored together at the beginning of the view.

If this is not the case, problems could occur when maintaining the view data with the standard maintenance transaction (transaction SM30).

The key is normally computed automatically for database views. If manual maintenance of the key flag was activated, you MUST store the key fields together at the beginning.

Procedure

Place all the key fields at the beginning of the view if you want to maintain the view data using the standard view maintenance transaction.
