Valid Characters  Locate the document in its SAP Library structure

In a US, all ABAP program sources are also stored as Unicode. As in ABAP Objects, you may only use the following characters as identifiers in programs for which the Unicode flag is set:

  1. Letters a - z and A - Z without the German 'umlauts'
  2. Numbers 0 - 9
  3. The underscore _

For compatibility reasons, the characters %, $, ?, -, #, * and / are also permitted. You should, however, use them only in exceptional cases where you cannot avoid them.

Note

To ensure that programs can be transported from a US to a NUS without any loss of information in the process of conversion, you should not use any characters for comments and literals even in a US that cannot be represented in an NUS.
