API to update the MDMproducts table

Hi All,

I have a products table and I have to update records in that. The field/column I am planning to update is a qualified, multi valued look up table. For a particular record I already have 10 items in that field. Iam planning to have one more entry in that field.

How do I do that?

Do I have to read that record first, read the entries in that look up field append the 11th record and put it back?

Iam using ABAP API's. Even in JAVA API the logic would be same I guess. Iam using UPDATE method but I am not able to update.

any suggestions would be appreciated.

Thank you,

Gajendra.
