Unable to get any buttons from Good Receipt PO form

Question

here's the code and there's nothing wrong with this as I know of
SAPbouiCOM.Item oCopyFromButton = (SAPbouiCOM.Item)oGoodReceiptPOForm.Items.Item("29").Specific;
This gives the error
Unable to cast COM object of type 'System.__ComObject' to interface type 'SAPbouiCOM.Item. This operation failed because the QueryInterface call on the COM component for the interface with IID 'BLABLA' failed due to the following error: No such interface supported (Exception from HRESULT: 0x80004002 (E_NOINTERFACE)).
the oGoodReceiptPOForm is the right form.  I've checked all the properties for it
Any idea ?

Hi Marc,
Specific property is for casting to specific items, like EditText, ComboBox, etc. That's a property of the Item class.
When you refere to an Item object, you don't need specific nor cast, because you're refering to the exact kind of object.
In your example oGoodReceiptPOForm.Items.Item("10000330") return an Item Object. So assing it to a Item is OK.
