Last Delta Incorrect, No new Delta update possible.

Hi Experts,

While loading data in PSA for 0OGL_ACCOUNT_ATTR, I am getting below error message when I trigger IP. I am in BI 7.3

In RSRV, I am getting below message

There was a red request at PSA Manage, I deleted it, after this problem occurring. Please guide me on this to fix.

Thanks,

Saravanan.
