BAPI for Exclude Sales BOM Header in MC90 (DP to SNP Release)

Hi SDN gurus,

I have a requirement for Exclude Sales BOM Header in MC90 (DP to SNP Release). I am creating a program for updating the existing variants for “DP to SNP Release”, such that the Sales BOM headers or the Output product of DP PDS are excluded from the product selection of the variant, such that the demands for header items is never released to SNP, i.e. Headers are excluded from release.

The logic is this, Based on Planning area (input) i will fetch the P.O.S from a table. Now based on P.O.S and (selection criteria APO PPM Name = “ DP* ” and BOM I/O ID = “ O ”), i have to find all the UNIQUE Stock Keeping Units in the above P.O.S.

Is there any Technical Solution or BAPI's available to execute and get the above mentioned results?
