After changing the Source of WEBI query its not showing any data

Hi All,

Really appreciate your help on below issue.

We have changed the source of WEBI report which is BEX query from Query 1 to Query 2.

Both the queries are identical with same fields except few fields which are having different description

while doing mapping all fields are correctly mapped as per technical name in BEX.

but after all changes while refreshing the report its not showing any data.
