Hi Ram,
The dataflow is there from very long time. This is Quality system and the problem is there after system refresh.
From the error ,message its show that there is some problem with the table BIC/B0000851.
But when i checked out RSTSODS table i got the below screenshot, and there its showing 0Employee_attr.
When I checked 0EMPLOYEE_ATTR datasource for PSA table, its showing /BIC/B0000149000 as the PSA table
