Diagnosis
You entered an index object of type M (Matchcode) or S (Strategicindex) that cannot be saved in the current structure for the followingreason:
All key fields of matchcode object tables, which also occur in thelogical database structure, are stored in the table TLDB. However, thistable has space for only 19 matchcode fields.
The matchcode object you tried to save here has more than 19 relevantkey fields. Since not all of these could be saved, the object could notbe saved either.
Therefore, this matchcode object is again replaced by the old object.

Procedure
Either enter a different index object of type M or S, or delete tablesbelonging to the desired matchcode object from the logical databasestructure.
