• What is the cause and solution for SAP error message RSM2180 - Inconsist. Reduction for DTA &1;Last reduc.req &2 > Calculated Max-SID &3 ?

  The SAP error message RSM2180 indicates an inconsistency in the reduction of Data Transfer Objects (DTA) in the context of SAP BW (Business Warehouse) or SAP HANA. This error typically arises during the process of data reduction, where the system is trying to reduce the data in a DTA but encounters a discrepancy between the last reduction request and the calculated maximum SID (Surrogate ID).
  Cause:
  The error message RSM2180 can be caused by several factors, including:
  
  Data Inconsistency: There may be inconsistencies in the data stored in the InfoObject or the DTA, leading to discrepancies in the SID generation.
  Incorrect Configuration: The configuration settings for the DTA or the InfoObject may not be set up correctly, leading to issues during the reduction process.
  Data Load Issues: Problems during data loading processes, such as incomplete or failed data loads, can lead to inconsistencies in the data.
  Manual Changes: Manual changes to the data or the structure of the InfoObject can also lead to inconsistencies.
  
  Solution:
  To resolve the RSM2180 error, you can follow these steps:
  
  
  Check Data Consistency:

  Run consistency checks for the InfoObjects involved to identify any discrepancies.
  
  
  
  Reprocess the Data:
  
  If the error is due to a failed data load, try reprocessing the data load for the affected InfoObject or DTA.
  Use transaction RSMO to monitor and manage data loads.
  
  
  
  Adjust Configuration:
  
  Review the configuration settings for the DTA and ensure that they are set up correctly.
  Check the settings for SID generation and ensure they align with the data model.
  
  
  
  Delete and Reload Data:
  
  If the issue persists, consider deleting the affected data and reloading it from the source system.
