• What is the cause and solution for SAP error message BRAINOLAPAPI129 - MDX statement does not contain a COLUMNS axis ?

  The SAP error message BRAINOLAPAPI129 indicates that there is an issue with the MDX (Multidimensional Expressions) statement being executed in the context of SAP BW (Business Warehouse) or SAP Analytics. Specifically, the error states that the MDX statement does not contain a COLUMNS axis, which is required for the query to be processed correctly.
  Cause:
  The primary cause of this error is that the MDX query being executed is missing the definition for the COLUMNS axis. In MDX, a query typically consists of two axes: the COLUMNS axis and the ROWS axis. The COLUMNS axis is where you define the measures or dimensions that you want to display as columns in the result set. If this axis is not defined, the query cannot be executed properly, leading to the error.
  Solution:
  To resolve this error, you need to ensure that your MDX query includes a proper definition for the COLUMNS axis. Here are the steps you can take:
  
  
  Review the MDX Query: Check the MDX statement you are using. Make sure that you have specified the COLUMNS axis correctly. A typical MDX query structure looks like this:
  SELECT 
      { [Measures].[Measure1], [Measures].[Measure2] } ON COLUMNS,
      { [Dimension].[Hierarchy].Members } ON ROWS
  FROM [Cube]
  Ensure that you have a valid set of measures or dimensions defined on the COLUMNS axis.
  
  
  Add Measures or Dimensions: If the COLUMNS axis is missing, add the necessary measures or dimensions to it. For example, if you want to display sales figures, you might add a measure like [Measures].[Sales] to the COLUMNS axis.
  
  
  Test the Query: After making the necessary adjustments, test the MDX query again to see if the error persists.
  
  
  Consult Documentation: If you are unsure about the correct syntax or structure of your MDX query, refer to the SAP BW or MDX documentation for guidance on how to construct valid queries.
  
  
  Related Information:
  
  MDX Basics: Understanding the basics of MDX, including the structure of queries and the significance of the COLUMNS and ROWS axes, can help prevent similar errors in the future.
  SAP BW Queries: Familiarize yourself with how SAP BW handles queries and the specific requirements for MDX statements within the SAP environment.
  Error Logs: Check the error logs or trace files in SAP BW for additional context or details about the error, which may help in troubleshooting.
  
  By ensuring that your MDX query includes a properly defined COLUMNS axis, you should be able to resolve the BRAINOLAPAPI129 error and successfully execute your query.
