Hi Ajay,
Thanks for your time!
I did create additional steps with the following validations in Prerequisite but still none of them are triggering (I activated trace).
SYST-TCODE = 'ME51N' AND COBL-SAKNR IN ZGL-5
COBL-VORGN = 'RMBA' AND COBL-HKONT IN ZGL-5
Also please note that Commitment Management active, which means just the validation should suffice and I don't need to work with BADI or user exits.
Thank you,
Devi
