DTP from ADSO to Master data is fetching full load data in delta

Hi All,

I am facing an issue. While running a delta DTP load it is fetching entire full records from advance DSO to Master data. Its a daily delta load part of process chain. And its picking full records daily. Can anyone help me what needs to bone to overcome this issue. We are using the parameter option of " Extract from online Database" in the DTP. Our system is BW on HANA 7.5 SP6. We have this issue earlier in 7.4 also

Thanks in advance.
