• Message text: Asynchronous costing not possible for network &

What causes this issue?

Network &V1& is header-assigned. You cannot use the asynchronous
network costing for header-assigned networks.

System Response

No costs were determined for network &V1&.

How to fix this error?

KPN026 - Details

• The SAP error message KPN026, which states "Asynchronous costing not possible for network &," typically occurs in the context of project systems or production planning when the system is unable to perform asynchronous costing for a network due to certain conditions not being met.
  
  Cause:
  
  Network Structure Issues: The network may not be properly structured or may have missing components, such as activities or relationships.
  Costing Variant Configuration: The costing variant used may not be configured to allow asynchronous costing.
  Status of the Network: The network or its activities may be in a status that does not allow costing (e.g., if the network is locked or not released).
  Missing Master Data: Required master data (like cost centers, activity types, etc.) may be missing or incorrectly configured.
  System Settings: The system settings for costing may not be correctly set up to allow asynchronous processing.
  
  
  Solution:
  
  Check Network Structure: Ensure that the network is correctly structured with all necessary activities
