Error when writing to TemSe

What causes this issue?

An error occurred as data was being written to the file.

How to fix this error?

Restart the program. If the problem proves to be more than just a
temporary one, check whether the file was able to accept data at all
(i.e. did it still have some space for data?). If this method does not
help, inform the SAP Hotline.
