• What is the cause and solution for SAP error message /INCMD/MSG029 - Predecessor and successor members in a relation cannot be products ?

  The SAP error message /INCMD/MSG029 indicates that there is an issue with the relationship between predecessor and successor members in a planning or forecasting context, specifically in the Integrated Business Planning (IBP) module. The error states that both the predecessor and successor members in a relation cannot be products. This typically occurs when you are trying to create a relationship between two product members in a way that is not allowed by the system.
  Cause:
  
  Incorrect Member Types: The error arises when both the predecessor and successor members are defined as products. In IBP, relationships are typically defined between different types of members (e.g., product to location, product to customer, etc.), but not between two products.
  Model Configuration: The configuration of the planning model may not allow for product-to-product relationships, which is a common restriction in many planning scenarios.
  Data Integrity Issues: There may be issues with the data integrity or the way the members are defined in the master data.
  
  Solution:
  
  Review Member Types: Check the types of the members you are trying to relate. Ensure that at least one of the members is not a product. For example, you might want to relate a product to a location or a product to a customer instead.
  Adjust Relationships: If you need to create a relationship between two products, consider whether you can achieve your goal through a different type of relationship or by restructuring your data model.
  Model Configuration: Review the configuration of your planning model in IBP. Ensure that the relationships you are trying to create are supported by the model's design.
  Consult Documentation: Refer to the SAP IBP documentation for guidance on valid relationships and member types. This can provide insights into how to structure your data correctly.
  Data Validation: Validate your master data to ensure that all members are correctly defined and that there are no inconsistencies.
