How To Fix AJ202 - Device &1 reg. &2 per. &3-&4: compress. table from user exit unclear

SAP Error Message - Details

• Message type: E = Error

• Message class: AJ - Billing program

• Message number: 202

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

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 in
which the calorific value district does not correspond to the calorific
value district that is passed on in parameter X_GCA.

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 AJ202 - Device &1 reg. &2 per. &3-&4: compress. table from user exit unclear ?

  The SAP error message AJ202 indicates an issue related to 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 AJ202 can occur due to several reasons:
  
  User Exit Configuration: The user exit that is supposed to handle the compression logic may not be properly configured or implemented. This can lead to ambiguity in how the compression should be performed.
  Data Inconsistency: There may be inconsistencies in the data that the compression routine is trying to process, which can lead to confusion in the logic.
  Missing or Incorrect Parameters: The parameters being passed to the compression routine may be incorrect or missing, leading to an unclear state.
  Custom Code Issues: If there is custom code involved in the compression process, it may contain bugs or logic errors that cause the process to fail.
  
  Solution:
  To resolve the AJ202 error, you can take the following steps:
  
  
  Check User Exit Implementation:
  
  Review the implementation of the user exit related to the compression process. Ensure that it is correctly configured and that all necessary logic is in place.
  
  
  
  Review Data:
  
  Check the data that is being processed for compression. Look for any inconsistencies or anomalies that could be causing the issue.
  
  
  
  Debugging:
  
  Use debugging tools to step through the compression process and identify where the logic is failing. This can help pinpoint the exact cause of the error.
  
  
  
  Check Parameters:
  
  Verify that all parameters being passed to the compression routine are correct and complete. Ensure that they match the expected format and values.
  
  
  
  Consult Documentation:
  
  Refer to SAP documentation or notes related to the specific user exit and compression process. There may be known issues or additional configuration steps required.
  
  
  
  SAP Notes:
  
  Search for relevant SAP Notes that may address this specific error. SAP frequently releases notes that provide fixes or workarounds for known issues.
  
  
  
  Testing:
  
  After making changes, conduct thorough testing to ensure that the compression process works as expected without triggering the error.
  
  
  
  Related Information:
  
  Transaction Codes: Familiarize yourself with relevant transaction codes such as KAE1 (for CO data compression) and KAE2 (for CO data compression settings).
  User Exits: Understand the specific user exits that are involved in the compression process, such as EXIT_SAPLKACD_001 or others that may be relevant.
  SAP Community: Engage with the SAP Community or forums to see if other users have encountered similar issues and what solutions they have found.
  
  By following these steps, you should be able to diagnose and resolve the AJ202 error effectively. If the problem persists, consider reaching out to SAP support for further assistance.
