SAP S/4HANA Error 5183: NULL Language Model Pointer
Description
This error indicates that SAP S/4HANA encountered a critical issue while attempting to parse an XML model string. The process was aborted because a required language model component was not found or accessible, resulting in a NULL pointer. This typically occurs when the system cannot locate essential linguistic resources needed for data processing.
Error Message
ERR_TEXT_COMMON_LANGUAGE_MODEL_NULL_POINTER
