ODBC Error -1029 Unit of height 1] field can not be updated
I m creating sales order by adding line items <b>using DIAPI</b>.
After that i delivered this sales order.
Then try to update delivered sales order by adding remarks.
<i><b>Problem Case:</b></i> Create sales order with two line item containg same item code using DIAPI.
Delivered this sales order.
And then update this delivered sales order then it shows me error msg:
ODBC -1029[Unit of height 1:RDR1] field can not be updated.
What could be the possible cause of this error ????
