Variable substitution for csv file

Hi Guys,

I am using Multimapping to generate 2 target messages and finally creating these 2 messges as csv files. But i need to use variable substitution (because dynamic configuration doesnt work in multimapping) to create the target files and i need to omit this node from content. i know if it is fixed length file we can use variable substitution and finally we can cut the variable in content conversion by using below method

fixedLengthToodShortHandling cut

Note:- I am using PI7.1

thanks,

madhu
