• What is the cause and solution for SAP error message EAML223 - Network &1 cannot be deleted because it is a linear network ?

  The SAP error message EAML223 indicates that a specific network (in this case, referred to as "&1") cannot be deleted because it is classified as a linear network. Linear networks are typically used in SAP for projects that involve linear structures, such as roads, pipelines, or railways, and they have specific characteristics that prevent them from being deleted in the same way as standard networks.
  Cause:
  The primary cause of this error is that the network you are trying to delete is defined as a linear network in the SAP system. Linear networks have specific dependencies and relationships with other objects, such as activities, segments, and possibly other networks. Because of these dependencies, the system restricts the deletion of linear networks to maintain data integrity.
  Solution:
  To resolve this error, you can consider the following steps:
  
  
  Check Dependencies: Investigate if there are any dependent objects (like activities or segments) associated with the linear network. You may need to delete or disassociate these objects before attempting to delete the network.
  
  
  Change Network Type: If the network does not need to be a linear network, you might consider changing its type to a standard network if that aligns with your project requirements. This can sometimes be done through the network's settings.
  
  
  Use Transaction Codes: Use transaction codes like CN22 (Change Network) or CN03 (Display Network) to review the network details and dependencies. This can help you understand why the network is classified as linear and what dependencies exist.
  
  
  Consult Documentation: Review SAP documentation or help files related to linear networks to understand their characteristics and the implications of deleting them.
  
  
  Seek Help from SAP Support: If you are unable to resolve the issue, consider reaching out to SAP support or your internal SAP team for assistance. They may provide insights specific to your system configuration.
  
  
  Related Information:
  
  Linear Networks: Understand the concept of linear networks in SAP, including how they are structured and their purpose in project management.
  Network Management: Familiarize yourself with network management in SAP, including how to create, modify, and delete networks.
  Data Integrity: Recognize the importance of data integrity in SAP and how certain restrictions are in place to prevent accidental data loss or corruption.
  
  By following these steps, you should be able to address the EAML223 error and manage your linear network appropriately.
