  SAP Error Message:
  WRF_AT899 Quantities are too large (quantity field overflow)
  
  
  Cause:
  This error occurs when a quantity value being processed in a transaction or program exceeds the maximum allowed size or length defined for the quantity field in SAP. Essentially, the system cannot handle the quantity because it is too large to fit into the field's data type or length constraints.
  Common scenarios include:
  
  Entering or calculating a quantity that exceeds the maximum number of digits allowed.
  Data inconsistencies or incorrect unit of measure conversions leading to unexpectedly large quantities.
  Custom programs or interfaces passing quantities larger than standard SAP fields can hold.
  
  
  Explanation:
  
  SAP quantity fields are typically defined with a fixed length and decimal places (e.g., QUAN field type).
  If a quantity exceeds the maximum allowed digits (including decimals), an overflow occurs.
  This is a safeguard to prevent data corruption or incorrect postings.
  
  
  
  Solution:
  
  
  Check the Quantity Value:
  
  Verify the quantity being entered or processed.
