  The SAP error message STC_CONT_CFG_ENTITY258 indicates that there is a data loss issue related to a key field in a configuration entity. Specifically, it means that the actual length of the data being processed exceeds the defined length for that key field. This can occur in various scenarios, such as during data migration, system upgrades, or when importing data.
