Hi,
While opening thread on scn, please use proper headlines and error descriptions.
No Clear on your issue.
Assuming as you may deleted request from psa and all existed request without order.
If your load is delta loads then you may face data missing problem.
at data source level never delete any request with out moving request to further data targets.
Whats your data source?
what kind of request you deleted? delta or full load?
Other than that order, while loading data to further are you facing any issue?
if its delta load, then you need find the records which are create in particular day and load them into bw by using repair full request.
Thanks
