FR646 - Details

• The SAP error message FR646 indicates that the table BSEG (which is the line item table for accounting documents) is not unclustered. This typically occurs in systems where the BSEG table is still using a clustered table format, which can lead to issues when trying to perform certain operations, such as archiving or data extraction.
  
  Cause:
  
  Clustered Table: In older versions of SAP, BSEG was implemented as a clustered table. This means that the data is stored in a way that combines multiple records into a single table entry, which can complicate data access and manipulation.
  System Configuration: The system may not have been properly configured to uncluster the BSEG table, or the necessary steps to migrate to an unclustered format have not been completed.
  Database Issues: There may be underlying database issues or inconsistencies that prevent the unclustered format from being utilized.
  
  
  Solution:
  
  
  Uncluster BSEG Table: The primary solution is to uncluster the BSEG table.
