• What is the cause and solution for SAP error message WRF_APC556 - Target value must be greater than &1 ?

  Certainly! Here's a detailed explanation for the SAP error message:
  
  SAP Error Message:
  WRF_APC556 Target value must be greater than &1
  
  
  Cause:
  This error occurs in SAP Advanced Planning and Optimization (APO), specifically within the Demand Planning or Supply Network Planning modules, when you enter or process a target value that is less than or equal to a specified minimum value (represented by the placeholder &1 in the message).
  
  The system expects the target value (e.g., forecast, planned independent requirements, or other key figures) to be greater than a certain threshold.
  The threshold value (&1) is dynamically inserted in the message and usually represents zero or another minimum allowed value.
  This validation is in place to prevent invalid or nonsensical planning data, such as negative or zero target quantities where only positive values make sense.
  
  
  Typical Scenarios:
  
  Entering a target quantity in Demand Planning that is zero or negative when the system requires a strictly positive number.
