variance in leaf level dynamic calc member formula data between non-DSO and DSO application

Summary:

We have a leaf level account member with member formula in a Non-DSO application.
The source accounts used in Member formula has data, but the dynamic calc member does not fetch data.

We converted the non-DSO application to DSO application in different environment.
The same leaf level account member with member formula in the DSO application is fetching data by using the source members in the formula.
Can anyone guide why it does not fetch data in Non-DSO but have data in a DSO application with same member formula?
