Variable substitution for Dynamic filename

Question

Hi All,
my Scenario is Proxy to file. and the receiver file should be a zip file of extension .dat.gz.
In mapping I tried as below. In signature I used one sender and two receiver messages.
SENDER:                         RECEIVER:(2messages)
MT_Product                       MT_Product
-----Row                              ---------Row
---------field1                         -----------field1
---------field2                         -----------field2
---------field3                         -----------field3
                                         MT_Poduct_1
                                           --------field5  
for field5 I mapped current date and I am trying to use it in Reciver file communication channel. will that be correct to use?
In receiver communication channel the file name is Product_%field5%.zip I used
and I used Module Configuration for content conversion and Zipping the file.
In variable substitution I used field5 for dynamic date.
field5-----------
payload:Messages,1,Message2,1,MT_Product_1,1,field5,1
Module Confuguration:
Guys! am on right path????? will this be possible????

Answer 1

Hello,
Why you are using multimapping? Just for defining target file name using var substitution - BTW, that too is incorrect. You cannot use Messages/Message 1 nodes in variable substitution.
Secondly, if I am not wrong the approach of defining dynamic zip file name using variable substitution won’t work because variable substitution will be executed once all the modules before standard call sap adapter gets executed. So during runtime, at var substitution step, ur file will actually be a text file instead of XML as a result u will get an exception.
So, if there is no specific objective of using multimapping then simply use DC.
