BDC code for Education Infotype

hi

This is an urgent requirement. Please help me out ASAP.

I have developed a BDC code for Infotype 22. I have certain checks to be performed on it before upload.

the checks are :

The certificate field (SLABS) depends on Educational establishment (SLART) and the combination of SLABS and SLART need to be checked in T517A table

Branch of study (SLTP1) depends on Educational establishment (SLART) and the combination of SLTP1 and SLART need to be checked in table T517Z table

If Educational establishment is not found, throw error “Educational Establishment not found” .

If Edu’ establishment found, and no corresponding SLABS found for that SLART, error should be “Certificate not found”. Similarly for SLTP1.

In addition, the country key need to be checked against T005 table for the correctness of the code..

Can you please tell me how to do it as im new to HR.

Thanks and Regards
