• What is the cause and solution for SAP error message RSDME421 - Define less than or equal to the max. allowed number (3) of mining fields ?

  The SAP error message RSDME421 indicates that you are trying to define more mining fields in a data mining model than the maximum allowed limit. In this case, the limit is set to 3 mining fields. This error typically occurs when you are working with SAP BW (Business Warehouse) or SAP HANA and trying to create or modify a data mining model.
  Cause:
  The error is caused by exceeding the maximum number of mining fields that can be defined in a data mining model. The system has a predefined limit (in this case, 3) for the number of mining fields that can be used in a single model. If you attempt to add more than this limit, the system will throw the RSDME421 error.
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Review Mining Fields: Check the mining fields you have defined in your model. Ensure that you are only using the necessary fields and that you are not exceeding the limit of 3.
  
  
  Remove Unnecessary Fields: If you have defined more than 3 mining fields, remove the ones that are not essential for your analysis or model.
  
  
  Reassess Model Requirements: If you need more than 3 mining fields for your analysis, consider whether you can combine some fields or if you can create multiple models that each use a subset of the fields.
  
  
  Consult Documentation: Review the SAP documentation for data mining models to understand the limitations and best practices for defining mining fields.
  
  
  Check Configuration: If you believe that your use case requires more than 3 mining fields, check if there are any configuration settings that can be adjusted to increase this limit. However, this may not always be possible, as it could be a hard limit set by the system.
  
  
  Seek Support: If you are unable to resolve the issue, consider reaching out to SAP support or your internal SAP BW/HANA team for further assistance.
