How To Fix MC368 - Function modules for lock object & could not be generated

SAP Error Message - Details

• Message type: E = Error

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

• Message number: 368

• Message text: Function modules for lock object & could not be generated

What causes this issue?

The function modules could not be generated for a lock object.

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?

Two function modules are generated for a lock object. The names of the
function modules are ENQUEUE_<nnn> and DEQUEUE_<nnn>, where <nnnn> is
the name of the lock object.
Program XDDENQAC newly generates these function modules for certain
lock objects because the function modules generated previously would no
longer satisfy a stricter ABAP/4 syntax check. For this reason, not
only the individual function module, but the whole function group will
no longer function correctly, which could cause abnormal program
termination as soon as a program requests an enqueue lock.
You should therefore try to activate the lock object in the ABAP4
Dictionary. (The function modules are also regenerated at this time).
If there is an error, further information about the error situation can
be found in the activation log. One frequent error is that due to
subsequent changes to the key, the key fields of the primary table are
not included in the lock object as lock arguments.
Correct this in the ABAP/4 Dictionary and activate the lock object.
You can also try to delete both function modules manually in transaction
SE37 as user DDIC. You might then get information about whether
locks exist for example on the function modules.

• What is the cause and solution for SAP error message MC368 - Function modules for lock object & could not be generated ?

  The SAP error message MC368 indicates that there is an issue with generating function modules for a lock object. This typically occurs when there is a problem with the lock object definition or the underlying database structure. Here are some potential causes, solutions, and related information for this error:
  Causes:
  
  Lock Object Definition Issues: The lock object may not be defined correctly in the Data Dictionary (SE11). This could include missing fields or incorrect data types.
  Database Issues: There may be issues with the underlying database, such as missing tables or incorrect table structures.
  Authorization Issues: The user may not have the necessary authorizations to generate function modules.
  Transport Issues: If the lock object was transported from another system, there may be inconsistencies in the transport.
  System Configuration: There may be configuration issues in the SAP system that prevent the generation of function modules.
  
  Solutions:
  
  
  Check Lock Object Definition:
  
  Go to transaction SE11 and check the definition of the lock object. Ensure that all fields are correctly defined and that there are no inconsistencies.
  If necessary, redefine the lock object and activate it.
  
  
  
  Check Database Structure:
  
  Ensure that the underlying database tables are correctly defined and exist in the database. You can use transaction SE14 to check and adjust database objects.
  
  
  
  Check Authorizations:
  
  Ensure that the user has the necessary authorizations to create and modify lock objects. This may involve checking roles and profiles assigned to the user.
  
  
  
  Transport Consistency:
  
  If the lock object was transported, check the transport logs for any errors. You may need to re-transport the object or manually adjust the definitions in the target system.
  
  
  
  System Configuration:
  
  Check for any system configuration issues that may be affecting the generation of function modules. This may involve consulting with your Basis team.
  
  
  
  Re-Generate Function Modules:
  
  After addressing any issues, try to regenerate the function modules for the lock object. You can do this by using transaction SE11 and selecting the lock object, then choosing the option to generate.

  SAP Notes: Check SAP Notes related to lock objects and function module generation for any specific patches or updates that may address known issues.
  
  
  Documentation: Review SAP documentation on lock objects and their usage to ensure that you are following best practices.
  
  
  If the issue persists after trying the above solutions, it may be beneficial to consult with SAP support or your internal SAP Basis team for further assistance.
