Generic Delta

Dear Experts,

I have a generic datasource delta enabled using date.

Upper limit is 0 and lower limit is 1.

So, it should theoretically pull delta from yesterday to today.

I loaded delta via infopackage to the psa.

I loaded again the same delta infopackage and it brings the same number of records.

Now, there are 2 same loading in the psa exactly same records.

To load the delta to the master data attribute, what kind of DTP should be used?

I think its full load DTP and not a delta dtp since delta is already in the psa.

Please advise.

Thanks.

regards

Pascal
