Exception condition “INCONSISTENCY” raised.

 I have encountered this error after saving Query using ABAP FM (usually you do this using Query Designer)

The case is usually that in database tables are still stored some referencies for elements (RSZELTXREF), that are not present in element table (RSZELTDIR)

To find out, where is the problem, run ANALYZE_RSZ_TABLES program through SE80 or SE38.

Take a look at part:

Table RSZELTXREF -> Query INCONSISTENCY error alert.
