keys that you want to switch between.

that you want to switch between. Note:
The change to the valid-from date (PP_FROM) or the valid-from time
(PP_FROM_TIME) for a payment plan change also leads to a new paymentplan history entry and is processed like a payment plan change.This means that you are not permitted to make changes to these twofields if individual distribution exists.
