  The SAP error message RSDD803 indicates that there is an issue with checking the mode of an aggregate in the SAP BW (Business Warehouse) system. This error typically arises when there is a problem with the aggregate's configuration or its underlying data model.
  Cause:
  The error message can occur due to several reasons, including:
  
  Invalid Aggregate Configuration: The aggregate may not be properly configured, or there may be inconsistencies in the data model.
  Data Model Changes: Changes in the underlying InfoObjects or InfoProviders that the aggregate relies on may lead to this error.
  Inconsistent Data: There may be inconsistencies in the data that the aggregate is supposed to summarize.
  Missing or Inactive InfoObjects: If the InfoObjects used in the aggregate are missing or inactive, it can lead to this error.
  Transport Issues: If the aggregate was transported from one system to another, there may be issues with the transport that need to be resolved.
  
  Solution:
  To resolve the RSDD803 error, you can follow these steps:
