Updated PO.saveFinish() method to enable a Resource Allocation to zoom to its originating document.
Please find the attached patch for PO.java.
The attached ZIP/Pack-In simply adds AD_Table_ID and Record_ID to the S_ResourceAllocation table and tab. The Resource => Allocation tab gets a Zoom button (Record_ID column).
My first thought was to add code to WAssignmentEditor.onEvent() to set the table and record similar to how the org is set; however, that is not possible since the S_ResourceAssignment record is typically created before the referencing record is created. For example, creating a Resource Assignment from a Sales OrderLine creates the assignment before the OrderLine is saved (has a record_id).
