Delta Load Updation

Hi All,

                     I have triggered an info package INIT with out data transfer then a full load in to PSA table then data moved to DSO -->Cube.

later i changed the same info package with DELTA option kept in a process chain i am waiting for some data to be added in to psa table but in process chain it is showing "No new data available" for Delta variant.

please suggest me where i went wrong.

thanks and regards
