How To Fix CACSBAS299 - Lock conflict in table &2 in form routine &1

SAP Error Message - Details

• Message type: E = Error

• Message class: CACSBAS - Commissions: General Service Messages

• Message number: 299

• Message text: Lock conflict in table &2 in form routine &1

What causes this issue?

A lock conflict has occurred while carrying out the activity to reset
the copy service. This conflict usually occurs in table &SYST-MSGV2& in
form routine &SYST-MSGV1&. The cause may be that more than one user is
executing program CACS_RESET_MAP or the transaction with the same name
(IMG activity <ZK>Reset Copying Services</>).
The lock conflict also often occurs when the interface for manual entry
of commission cases is open in one commission application or the
calculation of commission cases was triggered and then an attempt was
made to start program CACS_RESET_MAP for the <ZH>same</> commission
application.

System Response

Program CACS_RESET_MAP terminates when a lock conflict occurs.

How to fix this error?

Program CACS_RESET_MAP is usually only called to regenerate the form
routines of the copy services when changes have been made to Customizing
of the copy services. However the form routines are also regenerated in
the commission case, if required. In this case, you do not need to
execute report CACS_RESET_MAP or you can do so at a later date.
It may be advisable to regenerate the form routines if the number of
module pools is too large, the generated form routines are incorrect or
the management table CACS_MAP1 contains incorrect entries.
In this case you must determine which users are currently locking the
table (transaction SM12).
Request these users <ZH>not</> to calculate any commission cases for a
short period of time and to leave the interface for manual entry of
commission cases.
Restart program CACS_RESET_MAP.

• What is the cause and solution for SAP error message CACSBAS299 - Lock conflict in table &2 in form routine &1 ?

  The SAP error message CACSBAS299 indicates a lock conflict in a specific table during the execution of a form routine. This typically occurs when multiple processes or users are trying to access or modify the same data in a table simultaneously, leading to a deadlock or a situation where one process is waiting for a lock held by another.
  Cause:
  
  Concurrent Access: Multiple users or processes are trying to access or modify the same record in the database table at the same time.
  Long-running Transactions: A transaction that takes a long time to complete can hold locks longer than necessary, increasing the likelihood of conflicts.
  Inefficient Code: Poorly optimized code that accesses the database in a non-efficient manner can lead to unnecessary locking.
  Database Configuration: Certain database settings or configurations may lead to more frequent lock conflicts.
  
  Solution:
  
  Identify the Lock: Use transaction codes like SM12 to check for existing locks on the table. This can help identify which user or process is holding the lock.
  Optimize Code: Review the ABAP code in the form routine to ensure it is efficient and minimizes the time locks are held. Consider using SELECT FOR UPDATE judiciously.
  Reduce Transaction Time: If possible, break down long-running transactions into smaller units of work to reduce the time locks are held.
  Implement Retry Logic: If the application allows, implement a retry mechanism that can attempt the operation again after a short delay if a lock conflict occurs.
  Database Tuning: Consult with your database administrator to ensure that the database is configured optimally for handling concurrent access.
  User Training: Educate users on best practices for accessing the system to minimize lock conflicts.

  SM21: To check system logs for any related issues.
  ST22: To analyze dumps that may provide more context on the error.
  
  
  SAP Notes: Check SAP Notes for any known issues or patches related to the specific error message.
  Performance Monitoring: Use tools like ST03N to monitor performance and identify bottlenecks that may lead to lock conflicts.
  
  By addressing the underlying causes and implementing the suggested solutions, you can reduce the occurrence of the CACSBAS299 lock conflict error in your SAP environment.
