how can we setup the allocation to not pick-up the previously allocated source transactions

Allocation to not pick-up the previously allocated source transactions to the next run.
Normally, in allocations it needs to be incremental running. Only the new and updated transactions need to be included in the next run, otherwise it will always be duplicating and will cause a mess in allocation results.
Same in Exploitation allocation we have, it is incremental, those transactions that’s been processed won’t be processed again on the next run.
But the thing is , in our new allocation rules we are only using formula conditions, and not the Allocation rule condition.
