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

S7033 - Overview

• 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,
