• What is the cause and solution for SAP error message DB6PM891 - => The MDC Advisor cannot take account of the two time characteristics ?

  The SAP error message DB6PM891, which states "The MDC Advisor cannot take account of the two time characteristics," typically arises in the context of SAP HANA and its Multi-Dimensional Calculation (MDC) capabilities. This error indicates that there is an issue with the time characteristics defined in your data model, which prevents the MDC Advisor from processing the request correctly.
  Cause:
  
  
  Incompatible Time Characteristics: The error usually occurs when there are two time characteristics in your data model that are not compatible with each other. For example, if you have two different time dimensions (like fiscal year and calendar year) that are not aligned or cannot be aggregated together, the MDC Advisor will not be able to process them.
  
  
  Model Configuration Issues: There may be configuration issues in the data model or the way the time characteristics are defined. This could include incorrect settings in the data source or the way the time attributes are linked.
  
  
  Data Inconsistencies: If the underlying data has inconsistencies or if the time characteristics are not properly populated, it can lead to this error.
  
  
  Solution:
  
  
  Review Time Characteristics: Check the time characteristics defined in your data model. Ensure that they are compatible and can be aggregated together. If you have multiple time dimensions, consider whether they can be consolidated or if you need to separate them.
  
  
  Adjust Model Configuration: Go through the configuration of your data model in the SAP HANA studio or the relevant modeling tool. Make sure that the time characteristics are set up correctly and that there are no conflicting definitions.
  
  
  Data Validation: Validate the underlying data to ensure that there are no inconsistencies or missing values in the time attributes. Clean up the data if necessary.
  
  
  Consult Documentation: Refer to the SAP documentation for MDC and time characteristics to understand the requirements and limitations. This can provide insights into how to properly configure your model.
