[mnaem02]

Hi Experts

I am making one form where purchase order done and after that goods will be received fully or partially attached is sample in which i am trying to code on buton

when QTYreceived filled and then user click on button , then filled quntity received rows should be sum up in "Sumqtyrceived" field like "Sumqtyrceived=Sumqtyrceived+QTYreceived"

because Quantity are received partially and recorded in system
I am new in codes
please help
is there any sample of accdb from where i can learn and apply i have searched in googles but codes are very difficult to understand
respects your precious tiime
Form Name PO and below code tried from the google


Private Sub Command21_Click()
Dim strSQL As String


Dim rs As DAO.Recordset
strSQL = "SELECT PO.PO, PO.GRN, PO.ProductName, PO.Price, PO.QTYOrder, PO.TotalPrice, PO.QTYRecived, PO.SumQTYRecived " & _
"FROM PO " & _


"GROUP BY PO.PO, PO.GRN, PO.ProductName, PO.Price, PO.QTYOrder, PO.TotalPrice, PO.QTYRecived, PO.SumQTYRecived " & _
"HAVING (((PO.PO)=[Forms]![PO]![PO1])); "




Set rs = CurrentDb.OpenRecordset(strSQL)


With rs
If Not .BOF And Not .EOF Then
.MoveLast
.MoveFirst
While (Not .EOF)


SumQTYRecived = SumQTYRecived + QTYRecived
QTYRecived = 0




Wend
End If
.Close
End With


ExitSub


Set rs = Nothing
Exit Sub
Resume ExitSub
End Sub




After this issue solved i want to transfer whole data filed in GRN table because PO is updated frquenty with new grn number on partial received of quantity

Here is a link to a free, generic data model that deals with Customers, Orders and partial deliveries. It is generic in that it represents
the most common facts in this business area. It may be more detailed than you need, so you can add to/remove from as required.
The related business facts underlying the data model are here.

It is important to get your tables and relationships designed and tested to match your needs.You can use some "sample data" and test
model with pencil and paper before getting too deep into forms and code. When your model is tested and matches your needs, you
now have a blueprint to build your database.

Good luck.
