• What is the cause and solution for SAP error message LD090 - The exit takt cannot come before or at the same point as the entry takt ?

  The SAP error message LD090, which states "The exit takt cannot come before or at the same point as the entry takt," typically occurs in the context of production planning and scheduling within the SAP system, particularly when dealing with the configuration of production lines or work centers.
  Cause:
  This error arises when there is a mismatch in the timing configuration of the production process. Specifically, it indicates that the exit takt time (the time it takes for a product to exit the production process) is set to be less than or equal to the entry takt time (the time it takes for a product to enter the production process). This situation is logically incorrect because it implies that a product could exit before it has even entered, which is not feasible in a production environment.
  Solution:
  To resolve this error, you need to adjust the takt times in the relevant configuration settings. Here are the steps you can take:
  
  
  Review Takt Times: Check the entry and exit takt times for the relevant production line or work center. Ensure that the exit takt time is greater than the entry takt time.
  
  
  Adjust Configuration:
  
  Navigate to the configuration settings for the production line or work center in SAP.
  Locate the fields for entry and exit takt times.
  Modify the exit takt time to ensure it is greater than the entry takt time.
  
  
  
  Validate Changes: After making the adjustments, validate the changes by running the relevant production planning or scheduling transaction again to ensure that the error no longer appears.
  
  
  Test the Process: Conduct a test run of the production process to confirm that the changes have resolved the issue and that the production flow is functioning as expected.
  
  
  Related Information:
  
  Takt Time: Takt time is a measure of the amount of time available to produce a product in order to meet customer demand. It is calculated based on the available production time divided by the customer demand.
  Production Planning: Understanding the principles of production planning and scheduling can help prevent similar errors in the future. Familiarize yourself with the concepts of lead time, cycle time, and production flow.
  SAP Documentation: Refer to SAP's official documentation or help resources for more detailed information on configuring production lines and work centers, as well as best practices for managing takt times.
  
  If the issue persists after making the necessary adjustments, consider consulting with an SAP expert or your organization's SAP support team for further assistance.
