Answer Posted / b.gopala rao
Mapping Parameters: Mapping parameter is a constant value
which points to any datatype in the entire mapping. its
value will not be changed as earlier said.
Mapping variable: Mapping variable is same thing like
mapping parameter except its value will be changed in the
mapping.
For define the value you can give the intial value or you
can create mapping parameter file. But in the file you
should specify the folder name. session name .
Ex:
[foldername.sessionname]
$$parameter1=100;
Otherwise informatica server can not recognize
the session.
