Before using mapping parameters and mapping variables we should declare these things in mapping tab of mapping designer.

A mapping parameter cannot change until the session has completed unless a mapping variable can be changed in between the session.

Example:

if we declare mapping parameter we can use that parameter until completing the session,but if we declare mapping
variable we can change in between sessions.Use mapping variable in Transcation Control Transformation.

For Eg out_file_name name we can use mapping parameter
and last_modified_date we can use as mapping variable
