How To Fix IAOM093 - The EXPORT data cluster is too large for the application buffer

SAP Error Message - Details

• Message type: E = Error

• Message class: IAOM - Account Assignment Manager Messages

• Message number: 093

• Message text: The EXPORT data cluster is too large for the application buffer

What causes this issue?

There is an exception assigned to the class
'CX_SY_EXPORT_BUFFER_NO_MEMORY'. The reason for the exception is that
you have a data volume for which your installation does not have enough
resources. The shared buffer can only store objects up to a certain
size, which depends on the total size of the buffer. This maximum size
was exceeded during the operation which was terminated.

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?

Contact your SAP administrator for a further analysis of the problem.
He or she can increase the maximum size of exportable objects by
increasing the size of the shared buffer. This is defined using profile
parameter rsdb/obj/buffersize. For more information about this
parameter, see transaction RZ11. Note that for performance reasons, a
single object cannot reserve the majority of the buffer, so the maximum
object size allowed is considerably below the total size.

• What is the cause and solution for SAP error message IAOM093 - The EXPORT data cluster is too large for the application buffer ?

  The SAP error message IAOM093 indicates that the EXPORT data cluster being processed is too large for the application buffer. This typically occurs when trying to export a large amount of data using the EXPORT statement in ABAP, and the data exceeds the buffer size limit.
  Cause:
  
  Large Data Volume: The primary cause of this error is attempting to export a large internal table or data structure that exceeds the maximum size allowed for the application buffer.
  Buffer Limitations: The application buffer has a size limit (usually around 1 MB), and if the data being exported exceeds this limit, the error will occur.
  Inefficient Data Handling: Sometimes, the way data is structured or handled can lead to larger-than-necessary exports.
  
  Solution:
  
  
  Reduce Data Size: 
  
  If possible, reduce the size of the data being exported. This can be done by filtering the data or exporting it in smaller chunks.
  Instead of exporting a large internal table, consider exporting only the necessary fields or records.
  
  
  
  Use CALL FUNCTION: 
  
  Instead of using EXPORT, consider using function modules to handle large data sets. For example, you can use CALL FUNCTION to pass data between programs or sessions.
  
  
  
  Use TABLES Parameter: 
  
  If you are exporting data to a function module, use the TABLES parameter to pass data in a more efficient manner.
  
  
  
  Check Data Structure: 
  
  Review the data structure being exported. Ensure that it is optimized and does not contain unnecessary fields or large objects.
  
  
  
  Split Data: 
  
  If the data is too large, consider splitting it into smaller parts and exporting them separately.
  
  
  
  Increase Buffer Size: 
  
  In some cases, it may be possible to increase the buffer size in the SAP system settings, but this is generally not recommended as a first solution and should be done with caution.
  
  
  
  Related Information:
  
  ABAP Documentation: Review the ABAP documentation for the EXPORT statement and its limitations.
  SAP Notes: Check SAP Notes for any specific recommendations or patches related to this error.
  Performance Considerations: When dealing with large data sets, consider performance implications and best practices for data handling in ABAP.
  
  If the problem persists after trying the above solutions, it may be beneficial to consult with your SAP Basis team or SAP support for further assistance.
