How to make a customized field editable when PO is in Open status

Hi @Harshita , I believe the steps you have followed are correct and and it should enable the field.

If from workflow, it is not working, you can add below code snippet to the POOrderEntry extension graph to make it enable.

protected void POLine_RowSelected(PXCache cache, PXRowSelectedEventArgs e, PXRowSelected InvokeBaseHandler)
{
    if (InvokeBaseHandler != null) InvokeBaseHandler(cache, e);
    var row = (POLine)e.Row;

    if (row == null) return;

    var itemExt = row.GetExtension<POLineExt>();
    if (itemExt == null) return;


    POOrder order = PXSelect<POOrder, 
        Where<POOrder.orderType, Equal<Required<POOrder.orderType>>, 
        And<POOrder.orderNbr, Equal<Required<POOrder.orderNbr>>>>>
        .Select(Base, row.OrderType, row.OrderNbr);

    if (order != null && order.Status == POOrderStatus.Open)
    {
        PXUIFieldAttribute.SetEnabled<POLineExt.usrCustomField>(cache, row, true);
    }
    else
    {
        PXUIFieldAttribute.SetEnabled<POLineExt.usrCustomField>(cache, row, false);
    }
}

Hope, it helps!

Hi @Harshita ,

You can use POOrderEntry graph to extend as your first screenshot.
