I have a package where network file paths are set up as package parameters, and these parameters are referenced in package variables that concatenate with file names read from file enumeration loops. Something like @[$Package::parWorkingFIlePath] + @[User::usrXMLFileNamePath]
Everything works fine in VS. My deployment plan was to use environment variables to read in the testing/production file paths from environment variables to the parameters on the server. On the server all of the variables that reference the package parameters populated from the environment variables fail validation, with a message that the 'expression cannot be parsed'.
I saw a mention somewhere that environment variables cannot be referenced by package variables. Is this the case? If so what would be the best method to pass the folder paths to the package variables?
Thanks
Environment variables pass values to parameters, which are then read-only throughout package execution.
Package variables can reference the values of parameters (as passed in from an environment variable), no problem.
Does that help at all?
That is my understanding, and that is how the packages are built. but for some reason all of my package variables that reference the parameters show validation errors on the server (no problem in VS)
thanks
