If the GL Date is in a closed period, then system uses the first day of the first open period

Hi,

We are on EBS 12.1.3. In Payables we have a very specific issue with invoice GL dates. For older invoices on which we create new invoice lines the system is trying to insert for the new lines the GL date from invoice header, but because the GL date of older invoices are often in a closed period, the system will choose the first day of the next open period. Oracle informs us this is standard functionality logic on or after apicancb.pls 120.35.12010000.17 (See Doc ID 1959443.1).

We are on apicancb.pls 120.35.12010000.30 since 21st of April 2017. And this new business logic is causing us trouble during month-end period closing when we have 2 open periods (e.g. Jun-17 and Jul-17).  When we discard an 'old' line from a closed period invoice (e.g. Feb-17) in Jul-17, the system takes system date as GL date (e.g. Jul-17) for that invoice line, but when we then enter a new invoice line on the same invoice the system takes first day of the next open period (e.g. Jun-17). This is causing accounting differences.
