Smart SAP Assistant

• What is the cause and solution for SAP error message CO734 - Only enter start date for forwards scheduling ?

  The SAP error message CO734 ("Only enter start date for forwards scheduling") typically occurs in the context of production planning and scheduling within the SAP system, particularly when working with production orders or operations in the routing.
  Cause:
  This error arises when the system detects that both a start date and an end date have been entered for a scheduling operation, which is not allowed in forward scheduling. In forward scheduling, the system calculates the end date based on the start date and the duration of the operation. Therefore, only the start date should be specified.
  Solution:
  To resolve the CO734 error, you should:
  
  
  Check the Scheduling Parameters: 
  
  Go to the transaction where you are entering the scheduling details (e.g., CO01 for creating production orders).
  Ensure that you have only entered a start date and left the end date blank.
  
  
  
  Adjust the Scheduling Type:
  
  If you need to specify both start and end dates, consider switching to backward scheduling if that fits your planning needs. This allows you to set both dates, but it will change how the system calculates the schedule.
  
  
  
  Review the Routing and Work Center:
  
  Ensure that the routing and work center settings are correctly configured for forward scheduling. Sometimes, incorrect settings can lead to unexpected behavior.
  
  
  
  Consult Documentation:
  
  Refer to SAP documentation or help files for more detailed information on scheduling options and best practices.
  
  
  
  User Training:
  
  If this error is frequently encountered, consider providing training for users on how to properly enter scheduling information in SAP.
  
  
  
  Related Information:
  
  Transaction Codes: Common transaction codes related to production orders include CO01 (Create Production Order), CO02 (Change Production Order), and CO03 (Display Production Order).
  Scheduling Types: Understand the difference between forward and backward scheduling, as well as the implications of each on production planning.
  SAP Notes: Check for any relevant SAP Notes that might address specific issues or provide updates related to scheduling errors.
  
  If the problem persists after following these steps, it may be beneficial to consult with your SAP support team or a functional consultant who specializes in production planning.
