• What is the cause and solution for SAP error message CO358 - Routing selected without lot size ?

  The SAP error message CO358 indicates that a routing has been selected for a production order or process without specifying a lot size. This can occur in the context of production planning and control when the system requires a lot size to determine how many units of a product should be produced based on the routing selected.
  Cause:
  
  Missing Lot Size: The routing selected does not have a defined lot size, which is necessary for the system to calculate the production quantities.
  Routing Configuration: The routing may not be properly configured in the system, leading to the absence of lot size information.
  Master Data Issues: The material master or the routing master data may not have been set up correctly, leading to missing parameters.
  
  Solution:
  
  
  Define Lot Size in Routing:
  
  Go to the routing transaction (e.g., CA01 or CA02) and check the routing for the material in question.
  Ensure that a lot size is defined in the routing. You can specify a fixed lot size or a variable lot size based on your production needs.
  
  
  
  Check Material Master Data:
  
  Verify the material master data (transaction MM03) to ensure that the lot size is defined in the relevant views (e.g., MRP view).
  If necessary, update the material master to include the appropriate lot size.
  
  
  
  Review Production Order Settings:
  
  When creating or modifying a production order, ensure that the lot size is specified in the order. This can often be done in the order creation screen or through the order type settings.
  
  
  
  Consult Documentation:
  
  Review SAP documentation or help resources for specific details on how to set up routings and lot sizes in your version of SAP.
  
  
  
  Check Configuration Settings:
  
  If you have access to configuration settings, check the settings for production planning and routing to ensure that they are correctly set up to handle lot sizes.
