Mirth originalFilename rename

I have been trying to remove .dat from ${originalFilename} in destination when i tried to do this ${originalFilename}.txt it gave me like 1652807798759.dat.txt how can i get 1652807798759.txt only without .dat in it

I have tried to do this in Destination’s Transformer but no luck

channelMap.put('OrigFilename', sourceMap.get('originalFilename'));

var outFile = channelMap.get('OrigFilename');'outFile ' + outFile ); // i am getting outFile as null here


A simple replace should work:

//test it with a static string first, in real code use sourceMap.get('originalFilename').toString();
var outFile = '1652807798759.dat.txt' ; 
outFile = outFile.replace(/.dat/g, "");'outFile ' + outFile );
