• What is the cause and solution for SAP error message UJCTRL_EXCEPTION105 - Only one Category type dimension permitted for model &1 ?

  The SAP error message UJCTRL_EXCEPTION105 indicates that there is an issue with the configuration of a model in SAP Analytics Cloud (SAC) or SAP BW/4HANA. Specifically, it states that only one category type dimension is permitted for the model you are working with. 
  Cause:
  This error typically arises when you attempt to add more than one dimension of the category type to a model. In SAP, a category type dimension is used to categorize data, and the system restricts the model to having only one such dimension to maintain data integrity and consistency.
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Review Model Configuration: Check the dimensions defined in your model. Ensure that there is only one category type dimension. If you have multiple dimensions set as category types, you will need to modify your model.
  
  
  Modify Dimensions:
  
  If you have identified multiple category type dimensions, decide which one you want to keep.
  Change the type of the other dimensions from category to another type (e.g., attribute or measure) that fits your data model requirements.
  
  
  
  Recreate the Model: If the model is complex and changing dimensions is not feasible, consider creating a new model with the correct configuration from the start.
  
  
  Consult Documentation: Refer to the SAP documentation for your specific version of SAP Analytics Cloud or SAP BW/4HANA for detailed guidelines on dimension types and model configuration.
  
  
  Testing: After making the necessary changes, test the model to ensure that it functions correctly without triggering the error.
  
  
  Related Information:
  
  Dimension Types: Understand the different types of dimensions available in SAP models (e.g., category, attribute, measure) and their appropriate use cases.
  Modeling Best Practices: Familiarize yourself with best practices for data modeling in SAP Analytics Cloud or SAP BW/4HANA to avoid similar issues in the future.
  SAP Community: Engage with the SAP Community forums for additional insights and solutions from other users who may have encountered similar issues.
  
  By following these steps, you should be able to resolve the UJCTRL_EXCEPTION105 error and successfully configure your model.
