How To Fix S7033 - Selecting 'RFC, Update' can cause performance problems

SAP Error Message - Details

• Message type: E = Error

• Message class: S7 - Runtime Analysis: Message Texts

• Message number: 033

• Message text: Selecting 'RFC, Update' can cause performance problems

What causes this issue?

Selecting 'RFC, Update' can lead to system performance problems.

System Response

If the checkbox 'RFC/Update' is selected, potentially an ABAP runtime
measurement will be started on the target server for each RFC or update
call (sequential, synchronous RFC calls to the same destination do not
result in another ABAP runtime measurement starting).
So this is how multiple runtime measurements can be started within a
short space of time, which can result in a heavy system workload. This
is particularly the case with asynchronous RFC calls.

How to fix this error?

A warning is issued.

Procedure for System Administrators

Make sure that you really do need a detailed ABAP runtime measurement of
the ABAP source code that is executed on the RFC server or in the update
task. To determine the runtime of an RFC call or of a synchronous
update, no special measurement is required on the server side.

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

• What is the cause and solution for SAP error message S7033 - Selecting 'RFC, Update' can cause performance problems ?

  The SAP error message S7033 indicates a potential performance issue when selecting the 'RFC, Update' option in certain transactions or function calls. This warning is primarily related to the way Remote Function Calls (RFC) and update tasks are processed in SAP systems.
  Cause:
  
  Performance Impact: The message suggests that using 'RFC, Update' can lead to performance degradation. This is because the system may have to handle multiple update tasks concurrently, which can lead to increased load on the database and application servers.
  Resource Contention: When multiple RFC calls are made that require updates, it can lead to contention for resources, such as database locks, which can slow down the overall system performance.
  Synchronous vs. Asynchronous Processing: The use of synchronous RFC (sRFC) for updates can block the calling program until the update is completed, which can lead to longer response times for users.
  
  Solution:
  
  Evaluate the Need for RFC, Update: Assess whether the use of 'RFC, Update' is necessary for your specific use case. If possible, consider using asynchronous RFC (aRFC) or background processing to reduce the impact on performance.
  Optimize the Function Module: If you must use 'RFC, Update', ensure that the function module being called is optimized for performance. This includes minimizing database access, reducing the amount of data processed, and ensuring efficient coding practices.
  Batch Processing: If applicable, consider batching updates to reduce the number of calls made to the database. This can help alleviate performance issues by reducing the frequency of updates.
  Monitor System Performance: Use SAP performance monitoring tools to keep an eye on system performance and identify any bottlenecks that may arise from using 'RFC, Update'.
  Consult SAP Notes: Check for any relevant SAP Notes or updates that may address performance issues related to RFC and updates. SAP frequently releases patches and notes that can help improve system performance.
  
  Related Information:
  
  SAP Basis Administration: Understanding how SAP handles RFC and update tasks is crucial for Basis administrators. They should be familiar with the configuration and tuning of the SAP system to optimize performance.
  Transaction Codes: Familiarize yourself with transaction codes like SM50 (Work Process Overview) and SM66 (Global Work Process Overview) to monitor and analyze the performance of RFC calls and updates.
  SAP Community and Forums: Engaging with the SAP community can provide insights and solutions from other users who may have faced similar issues.
  
  By addressing the underlying causes and implementing the suggested solutions, you can mitigate the performance problems associated with the 'RFC, Update' selection in SAP.
