Hi Michael,
Thanks for your help but there is some misunderstanding.
when student booking to module A and ST-SM and ST-E relationship is created and ADATANR
for ST-SM and ST-E is also created.
After that student canceled module A and status of ST-SM and ST-E is changed.
Sometime later student booked to module A and ST-SM and ST-E is created again and ADATANR.
my question is is there any link between ST-SM ADATANR and ST-E ADATANR.
i am question becuase right now there is some bug in SAP module booking program so sometimes ST-E status is not changed correctly.
I want to know is there any link table between ST-SM ADATANR and ST-E ADATANR.
regards,
