Set a UDF Value on System Form using UI API

[Former Member]

Hi everyone,

I am wondering what's the best way of setting a UDF on system form.

Here is my situation:

I have a button on the sales quotation and this button opens a new sales order and sets U_OQUTNO value as the quotation's DocNum.

// oForm is Quotation Form

var oForm = Application.SBO_Application.Forms.Item(pVal.FormUID);

// activeForm is Sales Order Form

Application.SBO_Application.ActivateMenuItem("2050"); var activeForm = Application.SBO_Application.Forms.ActiveForm;

activeForm.Mode = SAPbouiCOM.BoFormMode.fm_ADD_MODE;

activeForm.Freeze(true);

// setting Quotation's DocNum to Sales Order's U_OQUTNO which is bound to Item_7

((SAPbouiCOM.EditText)activeForm.Items.Item("Item_7").Specific).Value = ((SAPbouiCOM.EditText)oForm.Items.Item("8").Specific).Value;

activeForm.Freeze(false);

This is working but it's so slow and also if the item is not visible the code throws an exception when setting value. I wrote code to copy quotation lines to sales order lines, as I mentioned before, this way is so slow. I researched in previously asked questions and found an answer that told about using XML is the fastest way to manipulating data on the screen. I tried like below:

var quotationDBDataSource = oForm.DataSources.DBDataSources.Item("OQUT");

string quotationXML = quotationDBDataSource.GetAsXML();

quotationXML = quotationXML.Replace(" encoding=\"UTF-16\" ", "");

XElement xDocQuotation = XElement.Parse(quotationXML);

string quotDocNum = xDocQuotation.Descendants("uid").First(x => x.Value == "DocNum").Parent.Element("value").Value;

var orderDBDataSource = activeForm.DataSources.DBDataSources.Item("ORDR");

string orderXML = orderDBDataSource.GetAsXML();

orderXML = orderXML.Replace(" encoding=\"UTF-16\" ", "");

XElement xDocOrder = XElement.Parse(orderXML);

// throws an exception that has message as there is no node called U_QUOTNO in XML

xDocOrder.Descendants("uid").First(x => x.Value == "U_OQUTNO").Parent.Element("value").Value = quotDocNum;

orderDBDataSource.LoadFromXML(xDocOrder.ToString());

I realized that ORDR table's XML hasn't got any node called U_QUOTNO. But there is a user-defined field called U_QUOTNO in ORDR table. So this scenario did not work for me.

Finally, what is the best way to set values on a form using UI API?
