Why Can't I Effective Date My Transaction?

I am trying to add an effective date to my transaction. However, the system isn't letting me enter it. I keep getting an error when I try to enter the effective date

The DDI Connect system allows you to perform effective dating on certain financial transactions. However, there are some rules that surround the use:

NOTE: DDI does not recommend using effective dating on a regular basis. This process should be the exception, not the rule

• You cannot effective date a transaction beyond the current business date, other than loan advances. So, if your system's business date is 08/31 and you are attempting to effective date a transaction to 09/01, you will receive an error. For loan advances, they will allow you to effective date up to 7 days in the future

• You cannot post across transactions, other than accruals. So, if you are attempting to effective date a transaction to a date prior to any other transaction (other than the accrual transactions), the system will give you an error

• Effective dating will not automatically re-calculate fields such as accumulated interest. If you effective date a transaction that has implications on the accrued or compounded interest, for example, you will have to perform financial adjustments to update those fields as needed

• Not all transactions allow for effective dating. Those that do allow it will have the Effective Date field
