• What is the cause and solution for SAP error message WTADDI438 - You have selected &1 materials; the upper limit is &2 ?

  SAP Error Message:
  
  WTADDI438 – "You have selected &1 materials; the upper limit is &2"
  
  Cause:
  This error occurs in SAP Warehouse Management (WM) or Extended Warehouse Management (EWM) when a user tries to process or select more materials than the system allows at one time. The system has a predefined upper limit on the number of materials that can be handled in a single operation (e.g., during a transfer order creation, posting change, or other warehouse processes). When the number of selected materials exceeds this limit, the system throws this error to prevent performance issues or overload.
  
  Explanation:
  
  &1 = Number of materials you have selected.
  &2 = Maximum allowed number of materials (upper limit).
  
  This limit is set to ensure system stability and performance during warehouse operations.
  
  Solution:
  
  
  Reduce the number of materials selected:
  
  Select fewer materials in your operation so that the count does not exceed the upper limit.
  
  
  Adjust the upper limit (if necessary and authorized):
  
  If your business process requires handling more materials at once, you can increase the upper limit parameter. This should be done carefully, considering system performance.
  
  The parameter controlling this limit is often found in SAP customizing or user-specific settings.
  In WM, this might be controlled by a parameter in transaction SPRO under Warehouse Management settings or via user-specific parameters.
  In EWM, check the relevant configuration or consult SAP notes/documentation.
  
  
  
  Split the operation:
  
  If increasing the limit is not feasible, split your operation into smaller batches, each within the allowed limit.
  
  
  
  Related Information:
  
  This message is common in warehouse processes involving mass selection or processing of materials.
  Check SAP Notes for your specific SAP version if you want to increase the limit or if you encounter performance issues.
  Always test changes in a development or quality system before applying to production.
  Consult your SAP WM/EWM administrator or Basis team if you need to adjust system parameters.
