I think Variable substitution, to get the file name dynamically, refers the target payload. Correct me if I am wrong. If i need a field from the source payload , is it possible?
The UDF is a bit confusing. Here , the input is the field from source. The output of the UDF is filename with the source field. Where should I map the output of the UDF ? I donot need to create any field in the target structure.
Your solution of using a UDF to get the file name from the source itself seems fine. But what do i need to give in the "Target file name scheme" which is a mandatory field?
>>But what do i need to give in the "Target file name scheme" which is a mandatory field?
It can be anything. However the option Use Adapter-Specific Message Attributes and File Name needs to be selected in the receiver adapter so that the filename that is set in the UDF will overwrite the one which is specified in the File Name Scheme in the CC.

Yes Possible. Dont use Variable Substution use Dynamic Configuration.
Check my reply to this thread
and
Variable sustution will require to have the data in the target message. If in case this data is not required in the receiver file content then you have to do FCC to remove it.
