How to get currently logged in user on 'Bill of Material' Form in Add-Mode

Dear All,

I am using a UDF on 'Bill of Material' Form in SAP. This UDF is named as Current_User. I want in this UDF the user name that is currently logged in to SAP. I am able to get user name at form load event. But when 'Bill of Material' Form comes in ADD Mode, the user name doesn't display. What can I do for this problem.? Here is my code:

public override void Handle_SBO_ItemEvent(string FormUID, ref SAPbouiCOM.ItemEvent pVal, out bool BubbleEvent)

{

BubbleEvent = true;

try

{

if ((mst_FormUIDModal != null))

{

if (FormUID != mst_FormUIDModal)

{

bool dbo_FormFound = false;

foreach (SAPbouiCOM.Form dsa_Form in this.SBO_Application.Forms)

{

if (dsa_Form.UniqueID == mst_FormUIDModal)

{

if (FormUID != mst_FormUIDModal)

{

if (this.SBO_Application.Forms.Item(mst_FormUIDModal).Selected == false)

{

this.SBO_Application.Forms.Item(mst_FormUIDModal).Select();

}

BubbleEvent = false;

return;

}

dbo_FormFound = true;

}

}

if (!dbo_FormFound)

{

this.mst_FormUIDModal = null;

}

}

}

if (pVal.BeforeAction == false)

{

switch (pVal.EventType)

{

case BoEventTypes.et_FORM_LOAD:

{

if (pVal.FormType == -672)

{

Program.Curr_User = SBO_Company.UserName;

doc_form = this.SBO_Application.Forms.GetForm(pVal.FormType.ToString(), pVal.FormTypeCount);

((SAPbouiCOM.EditText)doc_form.Items.Item("U_User").Specific).Value = Program.Curr_User;

}

} break;
