Hello. Could someone tell me how to write a script to create JE from Allocation Schedule please? I know if you go to Allocation Schedule page, there is a button Create Journal Entry And on Allocation Schedules list page, there is Enter link which allow us to create JEs. But I need to mimic that feature to run allocation schedules at once instead of clicking one by one. I don't see any information about Credit/Debit amount in Allocation Schedule. Could I know where that information is please?

Try creating an Allocation Batch. That runs multiple schedules at once. Note that annoyingly it will stop and not go on from an allocation schedule that produces no entries. Or at least it used to be that way unless they fixed it. so if you have some allocations that don't have activity or create an entry each time, I'd probably leave them out of the batch.
