The recording process with transaction FSE5N involves manoeuvring through a tree structure. This can cause data upload errors if the recording is not executed in the right manner.
The best way to tackle the recording is to proceed as usual to the second screen where the tree structure is located. At this point, press the button at the top of the screen which opens up all the nodes. Then go to the menu bar, choose "find" and type in the node you require. Choose the node again, enter the data into the position you require and repeat this for each node you need. Your template is created with the specific nodes and positions you have chosen during the recording.
