I want to set up an FME workflow which I can reuse for projects, in which input data differs. For this, I want to load different shape files into FME using a parameter (the shapefilename). These shape files have different attribute names, so I wanted to use the schema mapper to map these different attributes.
The problem is that I cannot get a dynamic reader to work properly (I used feature merge). When I load in the first shapefile for the first project, the reader sets the user attributes to the attribute names of the first shapefile . If I restart and load in the second shapefile , it won’t expose the attributes from the second shapefile (the attributes from the first shapefile remain!).
How can I set up the reader to be able to handle different input schemes and change the exposed attributes dynamically, based on the input files?
