GetGroupUpdateAggregate Method
Generates a group aggregate for use in another component's Update request.
Syntax
public String getGroupUpdateAggregate();
Remarks
There is not exposed a way to directly edit the contents of a line item group when submitting an Update request with a component from this package. You can change the Quantity, but you cannot change the line items contained inside the group line. The LineItemGroups component is used to parse a line item group aggregate. You may then make changes to the individual line items, and then call the GetGroupUpdateAggregate to return an xml aggregate containing your changes. This is then set to the Aggregate field of the line you wish to modify in your Update.
For instance, the following code changes the BillableStatus of all line items and line item groups in the Bill retrieved from QuickBooks.
Bill.Get("123456"); for (int i = 0; i < Bill1.LineItems.Count; i++) { if (!Bill.LineItems[i].GroupName.Equals("")) { // this is a group line LineItemGroups.GroupType = gtBill; LineItemGroups.ParseAggregate(Bill.LineItems[0].Aggregate); for (int j = 0; j < LineItemGroups.LineItems.Count) { LineItemGroups.LineItems[j].BillableStatus = bsHasBeenBilled; } LineItemGroups.QBXMLVersion = Bill.QBXMLVersion; // so that the proper fields are included in the update aggregate. Bill1.LineItems[i].Aggregate = LineItemGroups.GetGroupUpdateAggregate(); } else { // regular line item Bill.LineItems[i].BillableStatus = bsHasBeenBilled; } } Bill.Update();
