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

DT607 - Overview

• 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.
