Enabling DELTA for Generic DataSource

Hello all,

I created a generic data source in the source system(ECC) and Enabled for delta, by selecting "Calendar Day" and Field as "DATBI" SAVED & Activated and replicated to BI.

However, when I requested DELTA from BI using DELTA Info Package, it is displaying 0(Zero) records, though there r records in the source system.

I dont have DATBI field as a "selection" field in the Data Source. Is that the reason or any other reason.

Thanks in Advance,

Regards,

PNK

    Hi,

    Did you run the Init delta request before going for any delta request.

    Please first run Init delta with data transfer. This would fetch all the records existing in the underlying table. Based on the data pulled, datasource would set the delta pointer. So, any data changes after this pointer would be captured when you run the delta next time.

      Hi,

      Please note that the delta field cannot be selection field.

      As you have taken calendar day as delta field, you would only be able to fetch delta once on a particular day. Running more deltas on the same day would not fetch any more records.

      e.g. Once you have initialised the data, delta pointer would be set to a date, say x. Next when you run the delta on the same day, it will not fetch any data because the deltas till date x have already been extracter. On next day if you fetch the data, you would get the deltas created after the date x i.e. for x+1.

      The below thread should help you more on this.

    Hi,

    when u r trying to pull the data using Infopackage, the request in PSA is showing as yellow colour warning OR is it shown in green colour with zero records.

    In case it is shown as yellow colour warning then you may go to the ECC system ->sm58 ->execute ->F6 on each Idoc.
