B2B - Set Source file name to the DB Target

Situation:

We want to send the File name picked by our Event to the DB target but where can we get the the input file name?

Tip:

The Source file name is stored in "baseInputFileName" context variable that you can retrieve in Data Mapper by using get-context mapping function. You can apply this mapping rule on the target field in which you want to store the value of Source File Name picked by Event.
