Flat File field exclusion logic

Hello

We receive a FlatFile and convert it to IS document for mapping. Some flat file fields contains value “!”, which means that these fields have to be ignored.
Now it is tedeous procedure to have the condition implemented for each and every field, that not to map when “!” is the value.
Can any one suggest an method to implement a logic so that such field values are not transfered to Target document.

on the map step where u are mapping the ff document type to your canonical document type .u need to set the copy condition for each field while u map .
the condition can be %ffdoc/field%!=“!”.
this should eliminate all the “!” from mapping to your document .
