How To Fix 63400 - Table & exceeds maximum possible length

SAP Error Message - Details

• Message type: E = Error

• Message class: 63 - Messages for Real Estate Management

• Message number: 400

• Message text: Table & exceeds maximum possible length

What causes this issue?

Structure &V1& with a length of &V2& bytes as defined in the Data
Dictionary is transferred to the function module for the sorting of the
open items. However, the internal buffer of the function module can
only process structures with a maximum length of &V3& bytes.

System Response

Further processing of the program has been cancelled.

How to fix this error?

This is an error in the definition of the data structure which is used
to sort the open items. This data structure should contain key fields
and all excess fields which should make sorting possible. Other fields
could possibly also be added. All fields must be provided to the
program which calls up the sorting module. To ensure maximum
performance, you should be careful that the total number of fields is
not too large. The internal buffer of the sorting module is limited to
&V3& bytes. Change the definition of the transferred data structure so
that the total number of fields does not take up more space than this.

• What is the cause and solution for SAP error message 63400 - Table & exceeds maximum possible length ?

  The SAP error message "63400 Table & exceeds maximum possible length" typically occurs when a table or data structure in SAP is trying to exceed the maximum length allowed for a particular field or data type. This can happen in various scenarios, such as when you are trying to insert or update data in a database table, or when you are working with internal tables in ABAP programs.
  Cause:
  
  Data Length Exceeded: The data being inserted or updated exceeds the defined length of the field in the database table or internal table.
  Incorrect Data Mapping: There may be a mismatch between the data being processed and the expected data structure, leading to an attempt to store more data than allowed.
  Configuration Issues: Sometimes, configuration settings in the system may lead to unexpected behavior, causing data to exceed the defined limits.
  
  Solution:
  
  Check Data Length: Review the data being processed to ensure that it does not exceed the maximum length defined for the respective fields in the database table or internal table.
  Adjust Data Mapping: If you are using structures or mappings, ensure that the data types and lengths are correctly defined and match the source data.
  Modify Table Structure: If necessary and feasible, consider altering the database table structure to increase the length of the field that is causing the issue. This should be done with caution and typically requires proper authorization and testing.
  Debugging: If you are working with ABAP code, use debugging tools to trace the point where the error occurs and inspect the data being processed at that moment.
  Consult Documentation: Review SAP documentation or notes related to the specific transaction or program you are working with to see if there are known issues or recommendations.
