How do load system form matrix -Inventory-Goods Issue through SDK UI &DI

Question

While I am accessing system form matrix -Inventory Goods Issue/ Goods Receipt, the matrix object is not accessible.
Error is coming stating "Item 13 is invalid, where 13 is item uid for matrix.
So,How do load system form matrix -Inventory-Goods Issue(FORM 720/-720) through SDK UI &DIAPI.
Form Type: -720
How to get reference of System form matrix object -Inventory-GoodsIssue.
Some thing similar to CopyFrom functionality for -Inventory-Goods Issue.
Currently my client requirement is as follows.
I created a UDF ((U_ILC) Incoming Log Challan) for marketing documents. And, this field is added in the header level of Goods Reciept, Goods Issue documents.
1. Through Inventory->Goods Receipt (ILCNo.10), items are received. Assume, M00001, M00002 are the items received with qty, price, whse, account values.
2. Through Inventory->Goods Issue, item should be issued. In this Goods Issue Form, after entering U_ILC value as 10, pressing Tab, the GoodsIssue matrix should be loaded with the values of GoodsReceipt(IGN1 for U_ILC:10) document i.e. M00001,M00002 along with the same values as in GoodsReceipt of ILC:10.
The code is as follows:
If (( ( pVal.FormType = "-720" or pVal.FormType = 720) And pVal.EventType <> SAPbouiCOM.BoEventTypes.et_FORM_UNLOAD) And (pVal.Before_Action = False)) Then
            '// get the event sending form
            oForm = SBO_Application.Forms.GetFormByTypeAndCount(pVal.FormType, pVal.FormTypeCount)
            If pVal.ItemUID = "U_ILCNo" And pVal.EventType = SAPbouiCOM.BoEventTypes.et_LOST_FOCUS And pVal.Before_Action = False Then
                SBO_Application.MessageBox("ILC No. Lost Focus")
                oMatrix = oForm.Items.Item("13").Specific
                oColumn = oForm.Columns.Item("1")
                oEditItmCode = oColumn.Cells.Item(1).Specific
                oEditItmCode.Value = "07215090x606"
                oItem = oForm.Items.Item("U_ILCNo")
                oEdit = oItem.Specific
                SBO_Application.MessageBox(oEdit.String)
            End If
        End If
3. The code
oMatrix = oForm.Items.Item("13").Specific
is raising error. I have used Event Logger and breakpoints to see where the code is halting.
Help me, how to access the matrix of Goods Receipt/ Goods Issue and load based on the existing data.
Thanks in advance

HI
If your code is in the SBO_Application_ItemEvent then try using this line
oForm = SBO_Application.Forms.Item(strFormUID)
instead of
oForm = SBO_Application.Forms.GetFormByTypeAndCount(pVal.FormType, pVal.FormTypeCount)
