- &1 contains lower-case letters ?SAP Error Message: WPRO_XI_PROXY020 &1 contains lower-case letters
Cause: This error occurs when a proxy name or identifier in SAP PI/PO (Process Integration / Process Orchestration) contains lower-case letters. SAP naming conventions for proxies, especially in the context of XI (Exchange Infrastructure) or PI, require that certain names (like interface names, proxy names, or service names) be in uppercase letters only. The presence of any lowercase letters violates these naming rules, causing the system to throw this error. Explanation: SAP XI/PI proxies and interface names are case-sensitive and must be uppercase. This restriction is due to the underlying XML and WSDL standards and SAP's internal naming conventions. The error message WPRO_XI_PROXY020 specifically points out that the name (represented by &1) contains lowercase letters, which is not allowed.
