![]() So here in the session ‘s_sample_session_name’, the ‘’$$Param_test” holds the value 2012 and not the 2011 for the higher precedence by the session level parameter. The session level parameters are defined in the workflow’s parameter file with the session name, this has the precedence over the global parameters. These are the parameters defined in the whole workflow’s parameter files, directly as parameters. This is the least precedence level, defined as initial value in the mapping designer itself. ![]() There are different levels of precedence of the parameters, The parameter files are saved with an extension. Similarly any value from the ‘=’ till the end of the line shall be considered as the value to the respective parameter. The parameters are detected by the Informatica IS with a $$ and takes the parameter name from the $$ till the occurrence of the ‘=’ symbol, anything between $$ and = shall be considered as the parameter name.
