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.
