I can’t provide samples, but can explain it for what you need.
To be simple,
- In your main Flow Chart .xaml file, your DataTable variable should be under variables like normal.
- In each of your other .xaml files, your DataTable variable should be under Arguments and NOT under variables (so delete it from the variables tab). Set the Argument Type to IN/OUT; that way, the variable will retain its value going in and out of the workflow file (IN is used if the data ends at the file and doesn’t need to be returned, OUT is used if the data originates from the file, and IN/OUT is used if the data doesn’t end nor originates from the file.)
- Go back to your main Flow Chart and for each Invoke Workflow File activity that calls the .xaml files, click on Import Arguments.
- Next, enter in the DataTable variable name used in your main Flow Chart .xaml file next to the DataTable variable used in your other .xaml file. This way, the data from the other .xaml file will be stored in to your main variable.
Hopefully, this describes what you need in better detail.
