user exit

dear gurus,

we do not want GR before GI so we implemented user exit

Enhancement - MBCF0002

Functional Module - EXIT_SAPMM07M_001

Include - ZXMBCU02

but at the tome of confirmation through co11n system is throwing the below error:

Good Issue Not Posted In Operation Confirmation

Message no. SY499

why system is throwing this message it should be come in MB31 when i am skipping Gi
