How To Fix RS_DB_DB6559 - InfoCube &1: There are more than three MDC dimensions in metadata

SAP Error Message - Details

• Message type: E = Error

• Message class: RS_DB_DB6 - DB6-Specific Messages in SAP BW

• Message number: 559

• Message text: InfoCube &1: There are more than three MDC dimensions in metadata

What causes this issue?

While it is technically possible to use more than three MDC dimensions,
we recommend that you don't. Using more than three MDC dimensions can
lead to excessive table growth.

• What is the cause and solution for SAP error message RS_DB_DB6559 - InfoCube &1: There are more than three MDC dimensions in metadata ?

  The SAP error message RS_DB_DB6559 indicates that there are more than three Multi-Dimensional Cube (MDC) dimensions defined in the metadata for a specific InfoCube. This is a limitation in the SAP BW (Business Warehouse) system, where the maximum number of MDC dimensions allowed is three. When this limit is exceeded, the system generates this error message.
  Cause:
  The primary cause of this error is the configuration of the InfoCube, where more than three dimensions have been defined. This can happen during the design phase of the InfoCube when additional dimensions are added without considering the limitations imposed by the system.
  Solution:
  To resolve this error, you need to reduce the number of MDC dimensions in the InfoCube to three or fewer. Here are the steps you can take:
  
  
  Review the InfoCube Design: Open the InfoCube in the Data Warehousing Workbench (RSA1) and review the dimensions that have been defined.
  
  
  Identify Unnecessary Dimensions: Determine if any of the dimensions can be removed or consolidated. Consider the business requirements and whether all dimensions are necessary for reporting.
  
  
  Modify the InfoCube:
  
  If you find dimensions that can be removed, delete them from the InfoCube.
  If you need to keep all dimensions for reporting purposes, consider redesigning the InfoCube to use fewer MDC dimensions. This may involve creating new InfoCubes or using other structures like DataStore Objects (DSOs) to store some of the data.
  
  
  
  Activate the InfoCube: After making the necessary changes, activate the InfoCube again to ensure that the changes take effect.
  
  
  Test the InfoCube: After activation, test the InfoCube to ensure that it functions correctly and that the data can be loaded and reported as expected.
  
  
  Related Information:
  
  MDC Dimensions: Multi-Dimensional Cube dimensions are used to define the structure of the InfoCube and how data is stored and accessed. Each dimension can represent different attributes of the data.
  SAP BW Limitations: Be aware of the limitations and best practices when designing InfoCubes in SAP BW. This includes understanding the maximum number of dimensions, key figures, and other structural elements.
  Documentation: Refer to SAP documentation and notes for specific guidelines on InfoCube design and limitations. SAP Notes may provide additional insights or updates related to this error.
  
  By following these steps, you should be able to resolve the RS_DB_DB6559 error and ensure that your InfoCube is compliant with SAP BW limitations.
