GetAsXML hangs on SAPbobsCOM.Documents invoiceObject

Question

Hi there. We have recently moved a customer to a new server, and upgraded from SBO 2005 to SP01.
We have an addon that has worked smoothly before, that loops through invoices for a given date, and generates XML that is then sent to a third party which uses this for electronic invoicing instead of getting them on paper. The addon we use is written in C#, and the code is basically this:
String sql = "SELECT T0.DocEntry, T0.DocNum, T0.Comments, T0.PaymentRef FROM OINV T0 INNER JOIN OCRD T1 ON T0.CardCode = T1.CardCode INNER JOIN NNM1 T2 ON T0.Series = T2.Series  WHERE T0.DocDate = '" + date + "' AND T2.SeriesName = 'XML-UF'";
rs.DoQuery(sql);
int total = rs.RecordCount;
String[] xml = new String[total];
while(rs.EoF == false)
     int docEntry = (int)rs.Fields.Item(0).Value;
     int docNum = (int)rs.Fields.Item(1).Value;
     SAPbobsCOM.Documents invoiceObject = (SAPbobsCOM.Documents)MainClass.SBOCompanyObject.GetBusinessObject(SAPbobsCOM.BoObjectTypes.oInvoices);
     invoiceObject.GetByKey(docEntry);
        xml[t] = invoiceObject.GetAsXML();
     //... more happens here
     rs.MoveNext();
The problem is this: After moving to a new, improved server, the application hangs after xml[t] = invoiceObject.GetAsXML(); The cpu goes 100%, and it just hangs. After some 5-10 minutes it seems like it continues to the next row. This used to take no time at all on the previous PC where it ran. What might be the problem? Is there some XML-library that is missing on the new computer? Everything else seems to work fine, including other addons, but the GetAsXML() doesn't work as it should anymore.

Answer 1

I managed to reduce the 15-minutes of fame for the getAsXml() to 2.5 minutes by adjusting SBOCompanyObject.XmlExportType = SAPbobsCOM.BoXmlExportTypes.xet_ExportImportMode;
However, that is still waaay too slow. As I said, it took max 7-8 seconds in PL:06, and as there is a lot of invoices, I simply don't have the time to wait even 2 minutes for each.
Well, as time was running out, I have finally managed to implement a workaround for the problem, sort of. Since getAsXml() did not work as it should in pl45, I had to manually loop through Documents and Document_Lines and make the Xml myself, gladly omitting fields that I don't need. Luckily it seems to work fine. And I'm down to a couple of seconds again. Hopefully the getAsXml() will be fixed so that others don't have to stumble into the same problem as I, but maybe the function will work more smoothly for others, who don't have complex invoices with 200-300 lines based on several different orders.
