The CV may even abend with codes such as 3970, 3985 or 3990.
The definition of table procedure SYSCA.ODBC_INDEX, and the program which implements it, IDMSOINX, are out of sync.
Release 16.0 APAR QO89230 changed both SYSCA.ODBC_INDEX and IDMSOINX. This should no longer be a problem in r18.5/r19.0 but it is not uncommon for sites to not have appropriately updated their SQL catalogs.
Ensure that the definition of SYSCA.ODBC_INDEX in your SQL catalogs matches what is it the CAGJSRC(VIEWDDL) member for your current CA-IDMS release.
