What causes this issue?

When activating a <DS:TX.DDDOK_ENQU_OBJECT>lock object</>, two function
modules are generated which can be called in an ABAP program to lock or
unlock objects. The names of these function modules are formed from the
name of the lock object, whereby the prefix 'ENQUEUE_' is added for the
function module for locking and the prefix 'DEQUEUE_' is added for the
function module for unlocking.
The function modules are generated into specially reserved function
groups.

• What is the cause and solution for SAP error message MC679 - Function module & in function group & generated ?

  The SAP error message MC679 typically indicates an issue related to a function module within a function group that has been generated. This error can occur in various contexts, often related to the Material Management (MM) or Controlling (CO) modules, but it can also appear in other areas of SAP.
  Cause:
  
  Function Module Not Generated: The function module in question may not have been generated properly. This can happen if there were issues during the development or transport process.
  Transport Issues: If the function module was transported from one system to another (e.g., from development to production), there may have been errors during the transport process.
  Missing Dependencies: The function module may depend on other objects (like data elements, domains, or other function modules) that are not available or not activated.
  Authorization Issues: Sometimes, the error can be related to authorization problems where the user does not have the necessary permissions to execute the function module.
  
  Solution:
  
  Regenerate the Function Module: Go to the function module in the ABAP Workbench (transaction SE37) and regenerate it. This can often resolve issues related to the function module not being properly generated.
  Check Transport Logs: If the function module was recently transported, check the transport logs for any errors or warnings that might indicate what went wrong.
  Activate Related Objects: Ensure that all related objects (like data elements, domains, etc.) are activated. You can do this in the ABAP Workbench.
  Check Authorizations: Verify that the user has the necessary authorizations to execute the function module. This can be done by checking the user roles and profiles.
  Debugging: If the issue persists, consider debugging the function module to identify the exact point of failure. This can provide insights into what might be causing the error.
