Ankit,
What do you mean by the one one mentioned in bold? Are you using consumption group etc. while releasing? Check the horizon for which you are releasing and buckets in SNP. Are you checking in planning book or RRP3?
1) The forecast released in SNP was not matching exactly with what is there in DP.There are no conditions maintained while releasing the forecast.
What do you mean by this? Did this resolved your double counting issue?
2) I also tried releasing the forecast for that material from DP but values didn't get doubled they remained same.
Share some screen shots for the issue.
Regards
Rahul
