Stopping Non-Billed Budgets
When a Non-Billed Budget stop is initiated, either on request or because it has expired and is not being renewed, the Non-Billed Budget is transitioned to pending stop status. You can plug in an algorithm (of type SAIS-ST) on the SA Stop Initiation system event on the Non-Billed Budget SA type to automatically finalize and stop the SA (i.e. transition it to stopped status). If you don't use a SA Stop Initiation algorithm, the Non-Billed Budget is stopped the next time the SA activation background process runs.
To finalize a pending stop SA, the system first calls the stop SA algorithm plugged-in on the SA Stop system event on the SA type. The stop SA algorithm type ( SAST-NB) supplied with the base package:
• Distributes any credit on the Non-Billed Budget to the covered SAs (using the method described in Distributing Non-Billed Budget Credit)
• Distributes any excess credit remaining on the non-billed budget using the overpayment distribution algorithm for the account's customer class and the overpayment transfer adjustment type (specified as a parameter to the algorithm)
• Creates a trigger to cause the account to be reviewed by the account debt monitor
• Creates a customer contact (if the customer contact class and customer contact type parameters are populated)
Warning: 
If you do not plug in an SA stop algorithm that transfers the credit balance from the non-billed budget to its covered SAs (or an excess credit SA), the stopped Non-Billed Budget may have a credit balance. You must then manually distribute this credit.
After the SA stop algorithm is finished, the SA stop processing performs the following steps if the SA type has a special role of Non-Billed Budget:
• If the Non-Billed Budget is monitored, create adjustments to synchronize the current and payoff balance of covered SAs using the Adj. Type (Synch Current) adjustment type from the covered SAs' SA types
• Remove the covered SAs from the Non-Billed Budget
• Remove all the scheduled payments from the non-billed budget
• Create an adjustment to synchronize current and payoff on the Non-Billed Budget SA using the Adj. Type (Synch Current) adjustment type from the Non-Billed Budget's SA type
Note: 
Synchronizing current and payoff effectively sets the current amount to zero on the Non-Billed Budget SA, as the payoff amount should have been reduced to zero by the distribution and overpayment processing in the algorithm for SA Stop.
