How To Fix AJ201 - Device &1 reg. &2 per. &3-&4: compress. table from user exit implausible

SAP Error Message - Details

• Message type: E = Error

• Message class: AJ - Billing program

• Message number: 201

• Message text: Device &1 reg. &2 per. &3-&4: compress. table from user exit implausible

What causes this issue?

A volume correction factor procedure that requires calculation of
compressibility and/or supercompressibility through user exit <LS>
EXIT_SAPLEA54_001</> is active for the specified register. In this
case, however, the value could not be calculated because return table
y_table_compr_factors is implausible. It contains table entries having
a calculated compressibility or supercompressibility of zero.

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?

First analyze the cause of the termination in your user-defined user
exit. Inform the person who is responsible for programming the user
exit.
The person responsible for the program should note the following:
In the IS-U menu, choose <LS>Billing execution</> -> <LS>Billing
analysis</>.
Choose <LS>Settings</> -> <LS>General</>, then set the <LS>Debugging on
</> indicator.
Start a billing simulation with the affected contract. Enter TGHUEXIT
in the <LS>Breakpoint at</> field.
You branch immediately to the point where your user exit is called, and
you may be able to localize the error in debugging.

• What is the cause and solution for SAP error message AJ201 - Device &1 reg. &2 per. &3-&4: compress. table from user exit implausible ?

  The SAP error message AJ201 indicates an issue with the compression of a table in the context of a user exit. This error typically arises in the context of the SAP Controlling (CO) module, particularly when dealing with the compression of CO data in the database.
  Cause:
  The error message "Device &1 reg. &2 per. &3-&4: compress. table from user exit implausible" suggests that there is an inconsistency or an issue with the data being processed during the compression of the CO tables. The specific causes can include:
  
  Data Inconsistency: There may be inconsistencies in the data that are being compressed, such as missing or incorrect entries.
  User Exit Logic: The logic implemented in the user exit may not be handling certain scenarios correctly, leading to implausible data being generated.
  Configuration Issues: Incorrect configuration settings in the CO module can also lead to this error.
  Version Mismatch: If there are discrepancies between the versions of the SAP system and the user exit code, it may lead to unexpected behavior.
  
  Solution:
  To resolve the AJ201 error, you can take the following steps:
  
  
  Check User Exit Implementation: Review the code in the user exit to ensure that it is correctly handling all scenarios and that it is not generating implausible data. Make sure that the logic aligns with the expected data structure.
  
  
  Data Consistency Check: Perform a consistency check on the data in the relevant CO tables. Look for any missing or incorrect entries that could be causing the issue.
  
  
  Review Configuration: Verify the configuration settings in the CO module to ensure they are set up correctly. This includes checking settings related to data compression and user exits.
  
  
  Debugging: If you have access to the development environment, you can debug the user exit to identify where the implausible data is being generated.
  
  
  SAP Notes: Check the SAP Support Portal for any relevant SAP Notes that may address this specific error. There may be patches or updates that can resolve the issue.
  
  
  Consult Documentation: Review the SAP documentation related to the CO module and user exits to ensure that you are following best practices.
  
  
  Contact SAP Support: If the issue persists after trying the above steps, consider reaching out to SAP Support for further assistance.
  
  
  Related Information:
  
  User Exits: User exits are predefined points in the SAP code where you can add your own custom code. They are often used to enhance standard functionality without modifying the original code.
  Data Compression in CO: Data compression is a process used in SAP to reduce the size of data in CO tables, which can improve performance and manageability.
  Transaction Codes: Familiarize yourself with relevant transaction codes such as KAE1 (for CO data compression) and KAE2 (for CO data archiving) to help manage and troubleshoot CO data.
  
  By following these steps, you should be able to identify and resolve the underlying issue causing the AJ201 error message in your SAP system.
