Object &SYST-MSGV1& (object kind &SYST-MSGV2&): Lockable object needs a
unique lockable parent object at runtime.
You have selected the <LS>Locked Separately</> checkbox for an object
that has more than one parent object in the BOL (business object layer)
model.

• What is the cause and solution for SAP error message GENIL_WCF135 - Obj. &1 (obj. kind &2): Lockable object needs a unique parent at runtime ?

  The SAP error message GENIL_WCF135 indicates that there is an issue with the object hierarchy in the context of the SAP Gateway or the Business Object Layer (BOL) in the SAP CRM or SAP Gateway framework. Specifically, the error states that a lockable object requires a unique parent at runtime, which means that the system is unable to determine a unique parent for the object in question.
  Cause:
  
  
  Object Hierarchy Issues: The error typically arises when the object being processed does not have a unique parent in the context of the application. This can happen if:
  
  The object is part of a collection that has multiple parents.
  The object is incorrectly configured in the model or has been manipulated in a way that violates the expected hierarchy.
  
  
  
  Concurrency Issues: If multiple transactions are trying to access or modify the same object simultaneously, it can lead to locking issues, which may trigger this error.
  
  
  Configuration Errors: There may be issues in the configuration of the Business Object Layer (BOL) or the Generic Interaction Layer (GENIL) that lead to improper object relationships.
  
  
  Solution:
  
  
  Check Object Relationships: Review the object model to ensure that each lockable object has a unique parent. This may involve checking the configuration in the BOL and ensuring that the relationships are correctly defined.
  
  
  Debugging: Use transaction codes like SE80 or SE37 to debug the relevant BOL or GENIL components. Look for the specific object and trace its parent-child relationships.
  
  
  Review Code: If you have custom code that manipulates these objects, review it to ensure that it does not inadvertently create situations where an object could have multiple parents.
  
  
  Lock Management: Ensure that your application is managing locks correctly. If necessary, implement proper locking mechanisms to prevent concurrent access issues.
  
  
  Consult Documentation: Refer to SAP documentation or notes related to the specific version of the system you are using. There may be known issues or patches that address this error.
  
  
  SAP Support: If the issue persists, consider reaching out to SAP support with detailed information about the error, including the context in which it occurs, the specific objects involved, and any relevant logs.
  
  
  Related Information:
  
  Transaction Codes: Familiarize yourself with transaction codes like SE80 (Object Navigator), SE37 (Function Module), and SE11 (Data Dictionary) for debugging and analyzing the object model.
  SAP Notes: Check for any relevant SAP Notes that might address this specific error or provide guidance on best practices for object management in the BOL/GENIL framework.
  Community Forums: Engage with SAP community forums or user groups where similar issues may have been discussed, and solutions shared.
  
  By following these steps, you should be able to identify the root cause of the GENIL_WCF135 error and implement a solution to resolve it.
