How to configure allocations when the same GL account has different recurring periods?

Hi Team,

We have a requirement to create allocation rules for recurring journals related to rent payments.

For example:

• In the first month, rent of $100 is paid, and the total amount is moved to the source account 2345. This journal entry needs to be generated for 3 months.
• In the second month, rent of $300 is paid, again with the same source account 2345, but this journal entry needs to be generated for 6 months.

In this case, since the amount is moving to the same GL account, the system appears to be processing the allocation as expected.

Could you please advise how to configure the allocation rules in such scenarios, where the source and target accounts are the same, but the allocation periods differ.
