• What is the cause and solution for SAP error message L1029 - Total capacity less than capacity used ?

  The SAP error message L1029 "Total capacity less than capacity used" typically occurs in the context of production planning and capacity management. This error indicates that the total available capacity for a work center or production resource is less than the capacity that has already been allocated or used for production orders, planned orders, or other activities.
  Cause:
  
  Capacity Overload: The total capacity defined for a work center is insufficient to meet the demand created by production orders or planned orders.
  Incorrect Capacity Planning: The capacity planning settings may not reflect the actual available capacity due to incorrect data entry or configuration.
  Changes in Demand: An increase in production orders or changes in scheduling may lead to a situation where the existing capacity is no longer adequate.

  Solution:
  
  
  Review Work Center Capacity:
  
  Go to the work center configuration and check the total capacity settings. Ensure that the available capacity is correctly defined.
