I have noticed that there are double scripts in SAP Web Repository.
Example: Z.GUIXT.SAPMV45A.F4001.TXT and Z.GUIXT.SAPMV45A.E4001.TXT
The scripts are identical and the only difference is the character before
screen number: F and E. When we use GuiXT it is the E-version that the system uses. What is the F-version for?

'F' or 'E' is the language key; it is automatically inserted into the script key unless you use the "language independent" option in GuiXT profile.
