• What is the cause and solution for SAP error message AH184 - From-nominal load is zero ?

  The SAP error message AH184 ("From-nominal load is zero") typically occurs in the context of SAP's Advanced Planning and Optimization (APO) or similar modules where load planning and capacity management are involved. This error indicates that the system is trying to process a load calculation, but the "from-nominal load" value is zero, which is not acceptable for the operation being performed.
  Cause:
  
  Missing Data: The most common cause is that the system does not have the necessary data to calculate the load. This could be due to missing or incorrect master data, such as resources, production versions, or planning data.
  Incorrect Configuration: There may be issues with the configuration of the planning area or the planning book, leading to incorrect load calculations.
  Zero Demand: If there is no demand for a product or resource, the system may calculate a zero load, which can trigger this error.
  Capacity Constraints: If the capacity of a resource is set to zero or not defined properly, it can lead to this error.
  
  Solution:
  
  Check Master Data: Ensure that all relevant master data (e.g., resources, production versions, and planning data) is correctly maintained and complete.
  Review Planning Area Configuration: Verify the configuration of the planning area and planning book to ensure that they are set up correctly to handle load calculations.
  Analyze Demand: Check the demand for the product or resource in question. If there is no demand, consider whether this is expected or if there should be demand that is not being captured.
  Capacity Settings: Review the capacity settings for the resources involved. Ensure that they are defined correctly and that there are no constraints that would lead to a zero load.
  Run Planning Functions: If applicable, re-run the planning functions to see if the error persists after correcting any identified issues.
