My source is dat file. Intially in designer I can I import the file from my local. But later it gonna to come in shared location and Informatica need to pick it from there. I guess, for this I need to put parameter value 'Source file Directory' = '$PMSourceFileDir\' at session level in Workflow Manager. Now where is this Parameter file located? How can I get it to edit it so that I can put my parameter value also. Informatica is installed in my local but I am connecting to the repository of remote. Is there any other way so that Informatica can pick this dat file from a remote location. Please help.
$PMSourceFileDir is usually set as part of the Informatica server initialization, since it is a server variable. If you want to override it for your workflow, you can do so in a parameter file.
In your workflow monitor, go to the workflow designer tab, open your workflow.
Go to Workflow > Edit > Properties > Parameter file Name.
