JR53107: Incorrect discount given for order running total for customized promotions.

APAR status

• Closed as program error.

Error description

• The discount on the order is calculated incorrectly when
  OrderCalculate is called a second time through promotion engine
  evaluation.
  
  There is a cache in OrderRunningTotal that is normally cleared
  after the promotion engine evaluation, however, if a custom
  command that re-invokes the logic with some order updates, the
  cached result is returned instead of recalculating the new
  subtotal. This results in promotion applies to the already
  discounted subtotal to give additional unintended discount.
  

Local fix

  promotions.

  subtotal
