How To Fix VCH_LL106 - Unsupported mutually-dependent procedure chain in obj. dependency &2(&1)

SAP Error Message - Details

• Message type: E = Error

• Message class: VCH_LL - Messages for package VCH_LL

• Message number: 106

• Message text: Unsupported mutually-dependent procedure chain in obj. dependency &2(&1)

What causes this issue?

Object dependency &2(&1) consists of multiple sub-procedures. These
sub-procedures have mutual dependencies; this means that a value that is
calculated by a sub-procedure is used in a later sub-procedure. Since
<ZK>SAP HANA</> variant configuration processes all sub-procedures in
parallel, these mutually-dependent sub-procedure chains cannot be
calculated correctly.

The system issues an error message and will not allow you to continue with this transaction until the error is resolved.

• What is the cause and solution for SAP error message VCH_LL106 - Unsupported mutually-dependent procedure chain in obj. dependency &2(&1) ?

  The SAP error message VCH_LL106, which states "Unsupported mutually-dependent procedure chain in obj. dependency &2(&1)," typically occurs in the context of SAP's process chains, particularly when there are dependencies that create a circular reference or mutual dependency between different steps in the chain.
  Cause:
  
  Mutual Dependencies: The error arises when two or more steps in a process chain are mutually dependent on each other. This means that step A depends on step B, and step B also depends on step A, creating a circular dependency that cannot be resolved.
  Incorrect Configuration: The configuration of the process chain may have been set up incorrectly, leading to these unsupported dependencies.
  Changes in Process Chain: If changes were made to the process chain (like adding or modifying steps), it could inadvertently create mutual dependencies.
  
  Solution:
  
  Review Dependencies: Examine the dependencies between the steps in the process chain. Ensure that there are no circular references. You can do this by checking the properties of each step and their dependencies.
  Modify Process Chain: If you identify mutually dependent steps, you will need to modify the process chain to eliminate these dependencies. This may involve:
  
  Removing one of the dependencies.
  Reorganizing the steps in the process chain.
  Introducing intermediate steps that can break the circular dependency.
  
  
  Testing: After making changes, test the process chain to ensure that it runs without errors and that the dependencies are correctly configured.
  Documentation: Document the changes made to the process chain for future reference and to help prevent similar issues.
  
  Related Information:
  
  Process Chains: In SAP BW (Business Warehouse), process chains are used to automate data loading and processing tasks. Understanding how to configure and manage these chains is crucial for effective data management.
  SAP Notes: Check SAP Notes and Knowledge Base Articles for any specific guidance or patches related to this error message. SAP frequently updates its documentation and may provide specific solutions or workarounds.
  SAP Community: Engaging with the SAP Community can provide insights from other users who may have encountered and resolved similar issues.
