How To Fix DT607 - Key field & has type &: Buffering not possible, Transport restricted

SAP Error Message - Details

• Message type: E = Error

• Message class: DT - Table activation (incl. indexes)

• Message number: 607

• Message text: Key field & has type &: Buffering not possible, Transport restricted

What causes this issue?

A numeric type was used for a key field. A table of this sort cannot be
buffered.
When buffering, the table records for numeric values cannot be stored
in plain text. Therefore, no entries are found when buffered numerical
values are compared in the WHERE condition, although the table can
contain entries satisfying the compare criterion.
The contents of the table cannot be transported if you specify the full
key. You can only tranport table contents specified with a character
field, up to the first occurrence of a numeric key field.

System Response

The system issues an error message and will not allow you to continue with this transaction until the error is resolved.

How to fix this error?

You can enter "no buffering" as an attribute of the technical settings
and then repeat the activation process. The table is not buffered.
If you want to buffer the table, you must replace the type in the key
field by a character type, i.e. that you must modify the table.
If you want to transport the contents of a table, you can only do so
for records specified by a character key, up to the first occurrence of
a numeric field.

• What is the cause and solution for SAP error message DT607 - Key field & has type &: Buffering not possible, Transport restricted ?

  The SAP error message DT607 indicates that there is an issue with buffering for a specific database table. The message states that the key field has a certain type, and buffering is not possible because the transport is restricted. Here’s a breakdown of the cause, potential solutions, and related information:
  Cause:
  
  
  Key Field Type: The error typically arises when a key field in the database table is of a type that does not support buffering. For example, if the key field is a non-character type or a complex data type, buffering may not be allowed.
  
  
  Transport Restrictions: The table may have been defined with transport restrictions, meaning that it cannot be buffered in a way that would allow for efficient data retrieval across different environments (e.g., development, quality assurance, production).
  
  
  Table Configuration: The configuration of the table in the Data Dictionary (SE11) may not allow for buffering due to specific settings or constraints.
  
  
  Solutions:
  
  
  Check Table Definition: Go to transaction SE11 and check the definition of the table that is causing the error. Look at the key fields and their data types. If any key fields are of a type that does not support buffering, consider changing the design if feasible.
  
  
  Adjust Buffering Settings: If the table is not critical for performance and can be changed, you might consider adjusting the buffering settings. This can be done in the table definition in SE11 by changing the buffering option to "Buffering not allowed" or "Buffering allowed" based on your requirements.
  
  
  Review Transport Settings: If the table is marked as transport-restricted, you may need to review the transport settings. You can check the transport settings in SE11 and see if it can be modified to allow for buffering.
  
  
  Consult Documentation: Review SAP documentation or notes related to the specific table and its buffering capabilities. There may be specific guidelines or recommendations from SAP regarding the use of buffering for certain types of tables.
  
  
  Seek Help from SAP Support: If the issue persists and you cannot find a resolution, consider reaching out to SAP support for assistance. They may provide insights specific to your SAP version and configuration.

  Transaction Codes: SE11 (Data Dictionary), SE14 (Database Utility), SE78 (Transport Organizer).
  SAP Notes: Check for any relevant SAP Notes that may address this specific error or provide additional context.
  Performance Considerations: Understand the implications of buffering on performance and data consistency, especially in a multi-user environment.
  
  By following these steps, you should be able to diagnose and potentially resolve the DT607 error in your SAP system.
