  The SAP error message RSMPC304, which states "Complete roll-up of Cube not possible," typically occurs during the process of rolling up data in a data cube in SAP BW (Business Warehouse). This error can arise due to various reasons, and understanding the cause is essential for finding a solution.
  Causes of RSMPC304 Error
  
  
  Data Inconsistencies: There may be inconsistencies in the data that prevent the roll-up process from completing successfully. This can happen if there are missing or incorrect data records.
  
  
  Aggregation Levels: The roll-up process may be trying to aggregate data at a level that is not supported or does not have corresponding data.
  
  
  Data Locks: If there are locks on the data being processed (for example, if another process is currently accessing the data), this can prevent the roll-up from completing.
  
  
  Missing Master Data: If the master data required for the roll-up is missing or not properly maintained, it can lead to this error.
  
  
  Cube Structure Changes: Changes in the structure of the InfoCube (like adding or removing characteristics) can lead to issues during the roll-up process.
  
  
  Data Transfer Issues: Problems during data transfer from the source system to the InfoCube can also lead to this error.
