If I use IsEmpty to test whehter lookup is returning any record, it always returns false. But with the same data source if I use IsBlank then it work as expected...
If(
IsEmpty(LookUp([@'CDS DS'], some filters)),
//do somthing, it will never get here...
)
If(
IsBlank(LookUp([@'CDS DS'], some filters)),
//do somthing, it will work as expected
)
I thought IsEmpty is the one to be used with a table and IsBlank with a string...
what have I missed here? Why IsEmpty is always returning false...?

Hey @VijayTailor
Had another closer look at the reference on IsBlank, IsEmtpy and found
" the IsBlank and Coalesce functions test for both blank values or empty strings." ...
"In the context of the IsEmpty function, empty is specific to tables that contain no records."
So it all making sense now.
coz I am using LookUp and that will return a record I guess that doesn't really qualify as a table.
Thanks anyways.
