Hi Purva Kathuria,

Your question is not so clear, as i understood you need the following.

The entries in fields Z_CABJN, Z_POSNR should be unique.

If it is so, below is the answer.

Mark the fields Z_CABJN Z_POSNR as primary key.

So that the entries in those fields will be unique.

I think this is the correct answer to your question.

If, don't forget to reward.

hi purva,

If u want any fields as unique, then make those fields as primary fields.

To make a field as primary, just click on the check box beside to the field name in the ztable.

You can create a secondary index on just those two fields and specify that it is a unique undex.

Dear Purva,

Make Z_CABJN and A_POSNR as Primary keys and then use MODIFY statement. If the user makes an entry and if it doesnt exist then it will make a new entry in the database table and if it already exists then it will modify the existing entry.
