DBIF_RSQL_INVALID_REQUEST
highInvalid SQL Request Constructed by ABAP Database Interface
Module: ABAP / DBI
What this means
DBIF_RSQL_INVALID_REQUEST means the ABAP database interface (DBI) built an SQL statement that the database rejected as structurally invalid — not because of a data value issue (that would be DBIF_RSQL_SQL_ERROR), but because the SQL itself was malformed. This can happen when: a WHERE clause uses a field that does not exist in the table definition (possibly because a transport changed the table structure but the program was not updated); a FOR ALL ENTRIES IN clause is used with an empty internal table (which the DBI should prevent but can occur in some releases); or a dynamic WHERE clause is constructed with incorrect syntax.
Check ST22 for the table and SQL being executed. Enable SQL trace with ST05 and reproduce to see the exact SQL sent to the database. Verify in SE11 that all fields referenced in the WHERE clause exist in the current table definition. For dynamic WHERE clauses, add a syntax check. The classic FOR ALL ENTRIES with empty table issue is prevented by checking IF lt_tab IS NOT INITIAL before the SELECT.
