You can call FNC_TblOpDisableCoGroup in the contract function of the table operator to turn off the cogroup functionality.

If cogroup is disabled, table operators that handle multiple input streams may return different results on systems with different configurations where the number of AMPs differ. To get consistent results on different configurations, cogroup must be enabled.
