It is strongly recommended that you set up a separate CM Account when using this template to import payment history information.
This helps avoid running into check validation problems (e.g., the same check number was used in both the third-party application and in Vista™).
When using this import template, the system pulls information into an AP payment batch. If you pull imported transactions into AP Payment Posting prior to posting the batch, the system will default the Check Type field to I-Import, and you will be unable to make any changes to the transaction, as it is a previously paid transaction. You can add additional transactions from the system into the batch and process them alongside the imported transactions, however.
