• What is the cause and solution for SAP error message SDDL_PARSER_MSG520 - Lower limit of cardinality cannot be greater than 1 ?

  The SAP error message SDDL_PARSER_MSG520 indicates that there is an issue with the cardinality settings in a data model or configuration, specifically that the lower limit of cardinality cannot be greater than 1. This typically occurs in scenarios involving data modeling, such as when defining relationships between entities in SAP systems, particularly in SAP BW (Business Warehouse) or SAP HANA.
