Hi @armando_amador​ 

I am unclear on the acutal issue, if you are trying to set up Reader Table List , you can accomplish that via publishing parameters.

You can create a choice parameter with the value set to the table names.

e.g. If you have the following 4 tables in your geodatabase Airport, BusRoutes, Metrorail, BusStops

Now add the reader to the workspace

Do not select any Table, on the reader dialog, select Dynamic

Once the reader is add, In the Navigator Windows --> Reader --> Feature type to Read

Right-click and delete the publish parameter

Again right-click and "Link to Parameter" and from the drop-down, pick the parameter created above.

If you are trying to access the Writer FileAPI location on the FME Server repository.

For this, you will have to use publish parameter $(FME_DATA_REPOSITOR)\\foldername\\Output.gdb
