Hi Roberto,
Thanks for your advice.
"Is it possible by toggling multiple adj & report templates on a laptop and doing a series of send and refresh be the cause of this issue? ", interesting, yes this could be a cause: if a user open a de/report with a CV and change data and then open another de/report changing the CV (f.e. to see another period) and after send data from the first de, without refreshing it before, that could create a mess: you can create some tests to verify it.
-> Is there a way to prevent this thru BPC/Excel?
Do advice.
