How To Fix GH072 - Check your table extensions for effects on performance

SAP Error Message - Details

• Message type: E = Error

• Message class: GH - Help functions and tools in FI-SL

• Message number: 072

• Message text: Check your table extensions for effects on performance

What causes this issue?

You have added &V1& &V2& new fields to the customer include.

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?

Every field that you add as a customer add-on can can worsen your
system performance. This is especially true of fields that normally
have a high number of different versions in the system (e.g. orders,
WBS elements and so on). The volume of data in your database tables is
significantly increased through the inclusion of such fields. Longer
program run times and poorer performance in general are the result.
Check whether you really require all the fields that you have included
in the Flexible General Ledger. For performance reasons you should not
use any more fields than you absolutely require.

• What is the cause and solution for SAP error message GH072 - Check your table extensions for effects on performance ?

  The SAP error message GH072, which states "Check your table extensions for effects on performance," typically indicates that there may be performance issues related to the way table extensions are implemented in your SAP system. This message is often encountered during the execution of certain transactions or reports that involve database operations.
  Cause:
  
  Table Extensions: The error is usually triggered when there are custom extensions or modifications to standard SAP tables. These extensions can lead to performance degradation if not implemented correctly.
  Database Design: Poorly designed database structures, such as excessive joins or poorly indexed tables, can also contribute to performance issues.
  Data Volume: Large volumes of data in extended tables can slow down query performance, especially if the queries are not optimized.
  Inefficient Queries: If the queries accessing the extended tables are not optimized, they can lead to longer execution times.
  
  Solution:
  
  Review Table Extensions: Analyze the custom extensions made to the tables. Ensure that they are necessary and that they follow best practices for performance.
  Optimize Database Design: 
  
  Ensure that indexes are properly defined on the extended tables to speed up data retrieval.
  Avoid unnecessary joins and ensure that the database schema is normalized where appropriate.
  
  
  Performance Analysis: Use transaction codes like ST05 (SQL Trace) or ST12 (Single Transaction Analysis) to analyze the performance of the queries that are causing the error. Look for long-running queries and optimize them.
  Data Archiving: If the volume of data is large, consider archiving old or unnecessary data to improve performance.
  Consult SAP Notes: Check for any relevant SAP Notes that may address performance issues related to specific table extensions or provide guidance on best practices.
  Testing: After making changes, conduct thorough testing to ensure that performance has improved and that there are no adverse effects on functionality.
  
  Related Information:
  
  SAP Performance Tuning: Familiarize yourself with general performance tuning techniques in SAP, including database optimization, proper indexing, and efficient query design.
  SAP Community: Engage with the SAP Community forums to see if other users have encountered similar issues and what solutions they have implemented.
  Documentation: Review SAP documentation related to database performance and table management for additional insights and best practices.
  
  By addressing the underlying causes of the GH072 error and implementing the suggested solutions, you can improve the performance of your SAP system and reduce the likelihood of encountering this error in the future.
