In a few cases the result of an SAP report are a collection labels on the screen. You see in the object hierarchy the lbl for label and their column and row. lbl[53,0] means a label which starts at column 53 in row 0. In this example open fields,.
UiPath use the ID of the element to identify it.
But the ID could change, if more or less entries are visible. That’s where a search for a descriptive attribute would be helpful. Here an approach how to realize this with SAP GUI Scripting.
This approach uses the detection of the connection and session number from here. I added a tiny function to detect an Id of an UI element via its text (Function FindIdByText). This function loops over the area and compares each text of an element with the searched. If the text was found, the Id is returned.
'-Begin-----------------------------------------------------------------
'-Directives------------------------------------------------------------
Option Explicit
'-Function FindIdByText-------------------------------------------------
Function FindIdByText(oArea, strText)
Dim cntObj, i, Child, Id
On Error Resume Next
cntObj = oArea.Children.Count()
If cntObj > 0 Then
For i = 0 To cntObj - 1
Set Child = oArea.Children.Item(CLng(i))
If InStr(UCase(Child.Text), UCase(strText)) Then
Id = Child.Id
Exit For
End If
Next
End If
On Error Goto 0
FindIdByText = Id
End Function
'-Function FindSAPWindowsByHandle---------------------------------------
Function FindSAPWindowByHandle(hSAPWnd)
Dim SapGuiAuto, app, CollCon, oCon, CollSes, oSes, hWnd, i, j
Set SapGuiAuto = GetObject("SAPGUI")
If Not IsObject(SapGuiAuto) Then
Exit Function
End If
Set app = SapGuiAuto.GetScriptingEngine
If Not IsObject(app) Then
Exit Function
End If
'-Get all connections-------------------------------------------------
Set CollCon = app.Connections()
If Not IsObject(CollCon) Then
Exit Function
End If
'-Loop over connections-----------------------------------------------
For i = 0 To CollCon.Count() - 1
Set oCon = app.Children(CLng(i))
If Not IsObject(oCon) Then
Exit Function
End If
'-Get all sessions of a connection----------------------------------
Set CollSes = oCon.Sessions()
If Not IsObject(CollSes) Then
Exit Function
End If
'-Loop over sessions------------------------------------------------
For j = 0 To CollSes.Count() - 1
Set oSes = oCon.Children(CLng(j))
If Not IsObject(oSes) Then
Exit Function
End If
If oSes.Busy() = vbFalse Then
hWnd = oSes.findById("wnd[0]").Handle
If hSAPWnd = hWnd Then
FindSAPWindowByHandle = oSes.ID
End If
End If
Next
Next
End Function
'-Sub Main--------------------------------------------------------------
Sub Main()
Dim HandleSAPWindow
Dim sessionId, connectionNumber, sessionNumber
Dim pos, Len
HandleSAPWindow = CLng(WScript.Arguments.Item(0))
sessionId = CStr(FindSAPWindowByHandle(HandleSAPWindow))
pos = InStr(sessionId, "con[") + 4
Len = InStr(pos, sessionId, "]") - pos
connectionNumber = CLng(Mid(sessionId, pos, Len))
pos = InStr(sessionId, "ses[") + 4
Len = InStr(pos, sessionId, "]") - pos
sessionNumber = CLng(Mid(sessionId, pos, Len))
'-SAP GUI Script - Begin------------------------------------------------

Set SapGuiAuto = GetObject("SAPGUI")

End If
Set app = SapGuiAuto.GetScriptingEngine
If Not IsObject(app) Then
Exit Sub
End If
app.HistoryEnabled = False
Set connection = app.Children(CInt(ConnectionNumber))
If Not IsObject(connection) Then
Exit Sub
End If
If connection.DisabledByServer = True Then
Exit Sub
End If
Set session = connection.Children(CInt(SessionNumber))

Exit Sub
End If
If session.Info.IsLowSpeedConnection = True Then
Exit Sub
End If
Id = FindIdByText(session.findById("wnd[0]/usr"), _
WScript.Arguments.Item(1))
aId = Split(Id, "/")
Id = aId(UBound(aId))
app.HistoryEnabled = True

Here my test sequence.
It delivers with the SearchText variable “open” the correct result.
Now it is possible to use this Id as variable in the selector.
This example shows us very good how to combine the possibilities of SAP GUI Scripting with the possibilities of UiPath automation. On this way we can detect text on an SAP GUI for Windows screen fast. This approach can be a good complement or alternative to the procedures that already available in the portfolio of the UiPath activities.
