rename file in IR

Hello All,

I have a scenario to change the file name ex: OPER_XXXXXX_TRACK.fld.YYDDMM, where XXXXX value changes dynamically.

the output of the file name should be OPER_XXXXXX_TRACK.fld i.e with out having the YYDDMM,

is this possible using (Adapter Specific Message Attributes = ASMA)

or do we need to build a custom adapter module?

This is a ftp Communication Channel and no ESR development.

George.
