* Title: Calculate Open Item Amount in Invoice Currency
|
|
* Description:
|
|
* Add up total amount open for C_Invoice_ID if no split payment.
|
|
* Grand Total minus Sum of Allocations in Invoice Currency
|
|
*
|
|
* For Split Payments:
|
|
* Allocate Payments starting from first schedule.
|
|
* Cannot be used for IsPaid as mutating
|
|
*
|
|
* Test:
|
|
* SELECT C_InvoicePaySchedule_ID, DueAmt FROM C_InvoicePaySchedule WHERE C_Invoice_ID=109 ORDER BY DueDate;
|
|
* SELECT invoiceOpen (109, null) FROM AD_System; - converted to default client currency
|
|
* SELECT invoiceOpen (109, 11) FROM AD_System; - converted to default client currency
|
|
* SELECT invoiceOpen (109, 102) FROM AD_System;
|
|
* SELECT invoiceOpen (109, 103) FROM AD_System;
