How to import prior period AGIS Transaction in Current Open Period

Hi,

Is it possible to import the prior period AGIS Transaction in Current Open Period?

Scenario in detail -

There were couple of AGIS batches created in the prior period but business user did not import those batches in the prior period (due to ignorance)

Now the business user want to import the same in the current open period.

1) So is it possible to change the date of the AGIS transaction from the earlier period to the current month? ---AGIS Transaction Status is - Complete.

2) When I'm trying to change the inbound transaction, I can see the Update Transaction pencil icon is greyed out. Can not update the transaction. - Any solution on this?
