Account Payment, Transfer and Withdrawal wizards; changes to Credit Limit and Available Credit logic

In the Account Payment, Transfer and Withdrawal wizards a change has been made to the logic for Credit Limits and Available Credit.

The Credit Limit is now shown as at the date of the Transaction. Previously this was always shown as at today.

Note, if there are Credit Limits changes dated after the date of the Transaction a warning is still shown at the bottom of the Credit Limits block.

This has meant a change to the Summary Page 2, Account_CreditLimits function. Any scripts using this function may need to be updated. In addition there is a new function Account_CreditLimits_ForTransaction which takes in the date of the Transaction.

Note, the Account Transfer summary page has been updated to use summary pages version 2.

The following built-in summary pages have been updated:

"SummaryPage2_AccountPayment_PaymentSummary" updated to version 2.01 on 19/11/2013.
"SummaryPage2_AccountWithdrawal_WithdrawalSummary" updated to version 2.01 on 19/11/2013.
"SummaryPage2_AccountTransfer_TransferSummary" updated to version 2.00 on 20/11/2013.
"SummaryPage2_Account_Status" updated to version 2.01 on 20/11/2013.
