Hi Rizwana ,
I think your deltas got hampered ? Check your last delta request in 0Material right click Manage . If the load was red . Then you need to re-initialize again . Sometimes when your delta gets effected the Info package doesn't open and gives a short dump .
1.Delete the Init.
2. Replicate the DS and activate it .
3. Run IP with Init and Full load .
4. From the next loads your deltas will flow in .
Hope this helps ! Let me know how it goes .
Regards
Zeenath
