SAP Error Message - Details

• Message type: E = Error

• Message class: MC - Aggregate: views, matchcodes, lock objects

• Message number: 659

• Message text: Lock object & was activated without generating the function modules

What causes this issue?

The ENQUEUE and DEQUEUE function modules are not generated in the
selected activation mode. Activation caused no errors.

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?

This type of activation is only used for a release change if a
subsequent procedural step takes over the generation of the function

• What is the cause and solution for SAP error message MC659 - Lock object & was activated without generating the function modules ?

  The SAP error message MC659 indicates that a lock object was activated without generating the corresponding function modules. This typically occurs in the context of SAP ABAP development when a lock object is defined in the Data Dictionary (SE11) but the necessary function modules that manage the locking mechanism have not been generated.
  Cause:
  
  Lock Object Not Generated: When a lock object is created or modified in the Data Dictionary, the system requires the generation of function modules that handle the locking and unlocking of the objects. If this generation step is skipped or fails, the error MC659 will occur.
  Transport Issues: If the lock object was transported from another system and the generation step was not executed in the target system, this error can also arise.
  Authorization Issues: Sometimes, lack of proper authorizations can prevent the generation of the function modules.
  
  Solution:
  To resolve the MC659 error, follow these steps:
  
  
  Generate Function Modules:
  
  Go to transaction SE11 (Data Dictionary).
  Enter the name of the lock object that is causing the error.
  Click on the "Utilities" menu and select "Generate" or use the button for generating function modules.
  Ensure that the generation process completes successfully without any errors.
  
  
  
  Check for Errors:
  
  After generating, check the system log (transaction SLG1) for any errors that might have occurred during the generation process.
  If there are errors, address them accordingly.
  
  
  
  Transport Request:
  
  If the lock object was transported, ensure that the transport request is complete and that all necessary objects have been imported into the target system.
  
  
  
  Authorization Check:
  
  Ensure that you have the necessary authorizations to generate function modules. If not, contact your SAP security administrator.
  
  
  
  Testing:
  
  After generating the function modules, test the functionality that was causing the error to ensure that the issue is resolved.
  
  
  
  Related Information:
  
  Lock Objects: Lock objects in SAP are used to manage concurrent access to data. They ensure that data integrity is maintained when multiple users or processes attempt to access the same data simultaneously.
  Function Modules: Each lock object generates two function modules: one for setting the lock and another for releasing it. These function modules are crucial for the proper functioning of the locking mechanism.
  Transaction Codes: Familiarize yourself with relevant transaction codes such as SE11 (Data Dictionary), SE37 (Function Builder), and SLG1 (Application Log) for troubleshooting.
  
  By following these steps, you should be able to resolve the MC659 error and ensure that your lock objects function correctly within your SAP environment.
