• What is the cause and solution for SAP error message RTCMMD184 - Node & contains article assignment(s); creation not allowed ?

  The SAP error message RTCMMD184 indicates that there is an issue with the assignment of articles (materials) to a node in a hierarchy, typically in the context of SAP Master Data Management (MDM) or SAP Retail. The message states that the node already contains article assignments, and therefore, the creation of new assignments is not allowed.
