• What is the cause and solution for SAP error message SWDP_WB_TOOL712 - Parent node &1 has cardinality 0..1 or 1..1. "Primary" not allowed ?

  The SAP error message SWDP_WB_TOOL712 indicates an issue related to the cardinality of a node in a Web Dynpro application. Specifically, it suggests that the parent node has a cardinality of either 0..1 or 1..1, which means that it can have at most one instance. In this context, the term "Primary" is not allowed because the system expects that there can be multiple instances of a child node, but the parent node's cardinality restricts this.
  
  Cause:
  
  Cardinality Constraints: The parent node is defined with a cardinality of 0..1 or 1..1, which means it can only have one instance. If you are trying to define a child node as "Primary" (which implies that it can have multiple instances), this leads to a conflict.
  Modeling Error: There may be a modeling error in the data model where the relationship between the parent and child nodes is not correctly defined according to the business logic.
  
  
  Solution:
