Hi Gersh,
I too had the similar requirement to filter zero records, because in BPC MS we can use
WHEN SIGNEDDATA
IS <> 0
...
ENDWHEN
Where as the same is not supported in NW, for which in some cases I have been suggested to use %VALUE% with operators for the comparison, but it didn't work.
In addition to this compression has to be scheduled as a daily job and before the logic execution and we always need to ensure that there are no zero records in the DB.
Regards,
Rohit
