SAP Note details the conventions for naming logical systems relevant to ALE, EDI, and IDoc frameworks, focusing on compatibility and syntax prevention issues. Logical system names must exclude special characters to avoid technical problems in a multilingual environment. Valid characters include the 26 uppercase letters of the alphabet and the first 10 natural numbers, with the first character needing to be a letter. For ALE, the naming convention suggested is
<system id>clnt<client>, solution logical system names, english character set, function module scp_chars_are_syntactical, t90 sap system, <system id>, sap system, logical system, assigning names, create names
