Uploading the library file before you migrate a DataStage flow that contains user-defined functions
If a DataStage® flow that you are going to migrate from traditional DataStage contains user-defined functions, you must upload the library that contains the functions to successfully compile the flow. The library is contained in a .so file.
Procedure
What to do next
If you imported the ISX file for the flows that use your function library before uploading the library file, you must reselect the function library in the flow and save it. If you import the ISX file after uploading the library, the library is automatically added to the imported flows.
