• What is the cause and solution for SAP error message PPE4179 - Demand Planning only allowed with assembly ?

  The SAP error message PPE4179, which states "Demand Planning only allowed with assembly," typically occurs in the context of SAP Advanced Planning and Optimization (APO) or SAP Integrated Business Planning (IBP) when there is an attempt to perform demand planning on a non-assembly product. This error indicates that the system expects the product in question to be an assembly item, which is necessary for the demand planning process.
  Cause:
  
  Product Type: The product you are trying to plan is not defined as an assembly in the system. Demand planning is generally applicable to assembly products where components are planned based on the demand for the finished product.
  Master Data Configuration: The master data for the product may not be set up correctly. For example, the product might be defined as a raw material or semi-finished product instead of an assembly.
  Planning Area Settings: The planning area you are using may be configured to only allow demand planning for assembly products.
  
  Solution:
  
  Check Product Type: Verify that the product you are trying to plan is indeed an assembly. You can do this by checking the product master data in the relevant SAP module (e.g., SAP APO or SAP S/4HANA).
  Update Master Data: If the product is not set as an assembly, you may need to change its classification in the master data. This may involve updating the material type or the product hierarchy.
  Review Planning Area Configuration: Check the configuration of the planning area to ensure that it allows for demand planning on the types of products you are working with. You may need to consult with your SAP configuration team to adjust the settings.
  Consult Documentation: Refer to SAP documentation or help resources for specific guidance on how to configure products for demand planning.
