Background documentation Customer Name Ranges  Locate the document in its SAP Library structure

This section contains an overview table of customer name ranges. This table shows:

      the name lengths

      the standardized naming conventions

The initial characters “Y” and “Z” are reserved for customers. The following recommendation applies to companies that develop at several locations within the group:

      Z for branch

      Y for head office

If no group exists and you do not need to distinguish between branch and head office developments, you can use both reserved characters without restriction.

Note

You can only use special characters in names if these are explicitly allowed.
