• What is the cause and solution for SAP error message DT648 - Multiple selection not possible for buffering type ?

  The SAP error message DT648 ("Multiple selection not possible for buffering type") typically occurs when you are trying to perform a selection operation that is not compatible with the buffering type of the data being accessed. This can happen in various scenarios, such as when using certain transaction codes or reports that involve buffered tables.
  Cause:
  
  Buffering Type: The error is often related to the buffering settings of the database table you are trying to access. If a table is set to be buffered in a certain way (e.g., single record buffering), it may not support multiple selections or operations that require reading multiple records at once.
  Selection Criteria: The selection criteria you are using may involve multiple values or ranges that are not compatible with the buffering type of the table.
  Transaction or Report Limitations: Some transactions or reports may have limitations on how they can access buffered data.
  
  Solution:
  
  Check Buffering Settings: Review the buffering settings of the table in question. You can do this by going to the Data Dictionary (SE11) and checking the table's technical settings. If the table is set to "Single Record Buffering," consider changing it to "Full Buffering" if appropriate for your use case.
  Modify Selection Criteria: If possible, modify your selection criteria to use a single value or a compatible range that aligns with the buffering type.
  Use Alternative Methods: If the operation you are trying to perform is not supported due to buffering, consider using alternative methods to access the data, such as using a different transaction or report that does not have these limitations.
  Consult Documentation: Check SAP documentation or notes related to the specific transaction or report you are using for any known issues or recommendations regarding buffering and selection criteria.
  
  Related Information:
  
  Transaction Codes: The error can occur in various transaction codes, especially those that involve data retrieval from buffered tables.
  SAP Notes: Look for SAP Notes related to the specific transaction or table for any patches or updates that may address the issue.
  Performance Considerations: Be aware that changing buffering settings can have performance implications, so any changes should be tested in a development or quality assurance environment before being applied to production.
  
  If the issue persists after trying the above solutions, it may be beneficial to consult with your SAP Basis team or SAP support for further assistance.
