Question

Dear All
    In SAP B1 new version 8.82 have approval procedure. please help me a question below:
    In SAP. user account 01 create A/R credit memo DocNo(01) --> it save approval pending.
                user manager --> approval A/R credit memo DocNo(01) --> A/R credit memo DocNo(01) is created. --> End process. --> success.
    In Add On. I use account:    user account 01 Create A/R credit memo DocNo(02)  -> it save --> A/R credit memo DocNo(02) is created. -->End process. --> no success with approval procedure
    I want to Add On with approval procedure the same as in SAP
    And Add On Code below:
Input A/R invoice with Object = 13, DocEntry  > to add A/R Credit memo> no success with approval procedure
                Public Function SO_Return(ByVal DocEntry As Integer, ByVal ObjType As Integer) As Integer
        Dim i As Integer = -1
        Try
            Dim oObj As SAPbobsCOM.Documents
            If ObjType = 13 Then
                oObj = oCompany.GetBusinessObject(SAPbobsCOM.BoObjectTypes.oInvoices)
                ' set properties of the Order object
                oObj.GetByKey(DocEntry)
                Dim oARCreditMemo As SAPbobsCOM.Documents
                oARCreditMemo = oCompany.GetBusinessObject(SAPbobsCOM.BoObjectTypes.oCreditNotes)
                oARCreditMemo.CardCode = oObj.CardCode
                oARCreditMemo.DocDueDate = oObj.DocDueDate
                oARCreditMemo.NumAtCard = oObj.NumAtCard
                If oObj.Lines.Count = 1 Then
                    oARCreditMemo.Lines.ItemCode = oObj.Lines.ItemCode
                    oARCreditMemo.Lines.Quantity = oObj.Lines.Quantity
                    oARCreditMemo.Lines.Price = oObj.Lines.Price
                    oARCreditMemo.Lines.BaseEntry = DocEntry
                    oARCreditMemo.Lines.BaseType = SAPbobsCOM.BoObjectTypes.oInvoices
                    oARCreditMemo.Lines.BaseLine = 0 'first line
                Else
                    MessageBox.Show("A/R Invoice have " + oObj.Lines.ItemCode.ToString() + " rows, don't return. if want, use SAP.")
                    Return i
                End If
                i = oARCreditMemo.Add              
            End If
            Return i

Dear friend,
Thanks for replying,
But what does it mean "User must add the document through UI to trigger it"?
Because this function is built for user input data outside SAP, I have to develop by SDK with DI.
