X373: Invalid number of parameters (`number` expected) for stored procedure `ProcName`.

The number of parameters specified in your SQL CALL statement exceeds the number of parameters allowed by the ProcName stored procedure.

Verify that the PARMLIST column in the SYSIBM.SYSPROCEDURES table specifies the correct number of parameters for your stored procedure.

If the PARMLIST value is incorrect, correct it.
If the PARMLIST value is correct, edit the SQL CALL statement to pass the correct number of parameters to the stored procedure.
