• What is the cause and solution for SAP error message RS_SMA778 - Maximum part size must be at least more the double the min part size ?

  The SAP error message RS_SMA778 indicates an issue related to the configuration of the size parameters for data partitioning in the SAP system, particularly in the context of the SAP BW (Business Warehouse) or SAP HANA environments. This error typically arises when the maximum part size defined for data partitioning is not set correctly in relation to the minimum part size.
  Cause:
  The error occurs when the maximum part size is less than or equal to double the minimum part size. In data partitioning, the system requires that the maximum size be sufficiently larger than the minimum size to ensure efficient data processing and management. If this condition is not met, the system raises the RS_SMA778 error.
  Solution:
  To resolve this error, you need to adjust the configuration settings for the part sizes. Here are the steps you can take:
  
  
  Access the Data Partitioning Settings:
  
  Go to the relevant data model or InfoProvider in the SAP BW system.
  Navigate to the settings for data partitioning.
  
  
  
  Check the Minimum and Maximum Part Size:
  
  Review the current values set for the minimum part size and maximum part size.
  Ensure that the maximum part size is set to a value that is more than double the minimum part size.
  
  
  
  Adjust the Values:
  
  If the maximum part size is not compliant, increase it to meet the requirement (i.e., set it to more than double the minimum part size).
  For example, if the minimum part size is set to 100 MB, the maximum part size should be set to more than 200 MB.
  
  
  
  Save the Changes:
  
  After making the necessary adjustments, save the changes to the configuration.
  
  
  
  Test the Configuration:
  
  Run the data load or process that previously triggered the error to ensure that the issue has been resolved.
  
  
  
  Related Information:
  
  Documentation: Refer to the SAP Help Portal or relevant SAP Notes for detailed documentation on data partitioning and size configurations.
  SAP Community: Engage with the SAP Community forums for discussions and solutions related to similar issues.
  Performance Considerations: Properly configuring part sizes can have implications on performance, so it’s essential to consider the overall data volume and processing requirements when setting these parameters.
  
  By following these steps, you should be able to resolve the RS_SMA778 error and ensure that your data partitioning settings are correctly configured.
