How To Fix OIUGT069 - Network is not valid - multiple downstream nodes found

OIUGT069 - Overview

• Message type: E = Error

• Message class: OIUGT - Graphical Tool Message Class

• Message number: 069

• Message text: Network is not valid - multiple downstream nodes found

Diagnosis
The network has more than one downstream node, and entities in a
network should be linked to only one downstream node.
What To Do
Either remove the extra downstream node(s) causing the error, or create
connections as required.

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

OIUGT069 - Details

• The SAP error message OIUGT069, which states "Network is not valid - multiple downstream nodes found," typically occurs in the context of SAP's Integrated Business Planning (IBP) or similar applications that involve network planning and optimization. This error indicates that the system has detected multiple downstream nodes in a network configuration where it expects only one.
  
  Cause:
  
  Network 
  Configuration Issues: The error often arises when there are multiple downstream nodes linked to a single upstream node in a way that violates the expected structure of the network. This can happen due to incorrect data entry or configuration in the network model.
  Data Integrity Problems: If the data in the system is not consistent or has been corrupted, it may lead to multiple downstream nodes being recognized where only one should exist.
  Modeling Errors: Errors in the modeling of the supply chain or network can lead to this issue, especially if the relationships between nodes
