All physical matchcode IDs are case-sensitive

What causes this issue?

Only transparent matchcode IDs (update type 'I') exist for the
matchcode object. These are implemented with views. The SAPMACO
therefore need not construct any matchcode records in this case.

System Response

Processing is terminated if exactly one matchcode object is to be
maintained. If a like pattern is entered for the matchcode object, i.e.
if several matchcode objects are to be maintained, the next matchcode
object is maintained.

How to fix this error?

The database views must be created for the transparent matchcode IDs. If
they were not yet created, they must be created with transaction SE11.
The SAPMACO should not be called for matchcode objects which only
contain tranparent matchcode IDs since such transparent IDs are
implemented directly with a database view. This ensures data access
without calling SAPMACO.
