                           		  AccountAllocations\NewSettings. 
                           		
                        
Some of the flags' settings are provided for you to control the allocation processing, as follows:
- 
                                 
AccountAllocations\FlagOptions\AllowClosedSuspendedAccountCode- if this is set to Y this will allow the allocation if the account code used is closed/suspended. - 
                                 
AccountAllocations\FlagOptions\OverrideAllocations- if this is set to Y this will allow you to override any allocations in progress and the allocation process will continue.
