One usually doesn't modify or even create informatica mappings/sessions/workflows using simple unix tools. If you need to modify certain parameters, you better use parameter files, which you can modify using the standard unix tools or even create dynamically using Informatica.

I have a scenario where my source file name will be coming from one db table I have to read that value and pass it in the value of Source File Name in Session properties.

Till now I have tried like I have created 2 sessions where the 1st session will read the db table where the source file name is stored and store it in one mapping variable and in post success variable assignment I am assigning the mapping variable value to workflow variable and in the next main session I am trying to give the workflow variable in the session file name attribute .

But it is showing error like below

fail to expand variables in file field [$$WL_File].

How can I achieve this.

Please suggest some ideas.
