Create dynamic file name in BizTalk 2013

i new biztalk , have been tasked developing orchestration transfer incoming file ftp server. filename has include current date timestamp. inside expression shape tried using simple command assign current year string variable:

fileyear = system.datetime.now.tostring("yyyy");

seems simple enough, when go orchestration debugger , step through orchestration discover variable fileyear not assigned value when step through expression shape, value remains "null".

is wrong approach?

hi,

please try this

newfilename = newfilename + "output_" + system.datetime.now.year.tostring() + "-" + system.datetime.now.month.tostring();     message_2(file.receivedfilename) = newfilename;
