Use

The special characters /, \, and ? (forward slash, back slash, and question mark) are not allowed in URLs, therefore the system did not create any folders for users in the userhome repository if the user ID contained one of these characters.

To support user IDs containing these special characters, the folder IDs in the userhome repository are encoded as follows as of SPS 18 if the user ID contains one of the following characters:

●      ~ à ~u1

●      / à ~u2

●      ? à ~u3

●      \ à ~u4

The tilde is the encoding prefix, therefore it is also encoded.

 

Effects on System Management

If the userhome repository already contains folders that have a tilde (~) in their ID, you have to migrate these folders.

You must migrate these folders before a user with a tilde in his or her user ID logs on to the portal for the first time. Otherwise, the system creates a new folder for this user in the userhome repository.

A servlet is provided for the migration. For more information, see SAP Note 961747.
