• What is the cause and solution for SAP error message DMU328 - Only configurable &1 are allowed on node in intial layer (E) ?

  The SAP error message DMU328 indicates that there is an issue with the configuration of a product in the context of variant configuration (VC) or dynamic modification of units (DMU). Specifically, the error states that only configurable items are allowed on a node in the initial layer of a configuration model.
  Cause:
  
  
  Non-configurable Item: The error typically arises when a non-configurable item is being used in a configuration model where only configurable items are permitted. This can happen if the item is not set up correctly in the system or if it is mistakenly included in a configuration node that requires configurable items.
  
  
  Incorrect Model Structure: The structure of the configuration model may not be set up correctly, leading to the inclusion of non-configurable items in a layer that only allows configurable items.
  
  
  Data Integrity Issues: There may be issues with the data integrity of the configuration model, such as missing or incorrect settings for the items involved.
  
  
  Solution:
  
  
  Check Item Configuration: Verify that the item in question is indeed a configurable item. You can do this by checking the material master data in SAP to ensure that the item is marked as configurable.
  
  
  Review Configuration Model: Examine the configuration model to ensure that only configurable items are included in the initial layer. If non-configurable items are present, they should be removed or replaced with configurable alternatives.
  
  
  Adjust Model Structure: If the model structure is incorrect, you may need to adjust the configuration model to ensure that it adheres to the rules of variant configuration. This may involve re-structuring nodes or layers to comply with the requirements.
  
  
  Data Consistency Check: Perform a data consistency check to identify any discrepancies or issues within the configuration model. This can help in identifying any underlying problems that may be causing the error.
  
  
  Consult Documentation: Refer to SAP documentation or help resources for guidance on setting up configurable items and configuration models correctly.
