• What is the cause and solution for SAP error message CN031 - Production versions with standard networks are not possible ?

  The SAP error message CN031 indicates that there is an issue with the production version configuration in the context of standard networks. This error typically arises when you attempt to create or process a production order that references a production version that is not compatible with standard networks.
  Cause:
  The primary causes of this error include:
  
  
  Production Version Configuration: The production version you are trying to use is configured to not allow standard networks. This can happen if the production version is set up for a different type of production process (e.g., discrete manufacturing) that does not support standard networks.
  
  
  Network Type: The production version may be linked to a network type that is incompatible with standard networks. Standard networks are typically used for repetitive manufacturing or process industries.
  
  
  Missing or Incorrect Master Data: There may be missing or incorrect master data related to the material, routing, or production version that is causing the incompatibility.

  Ensure that all relevant master data (material master, routing, work center) is correctly configured and linked to the production version.
