• What is the cause and solution for SAP error message MS407 - Variant name protected (prefix = &) ?

  The SAP error message MS407 indicates that a variant name is protected, specifically when the prefix is "&". This typically occurs when you are trying to create or modify a variant in SAP that has a name starting with the "&" character, which is reserved for system use or is protected by the system.
