1) To enter an order on behalf of a customer go to module CAT_Customers -> search for a customer -> Select 'Login' from the 'Change User' column. This is better than editing an existing order because it ensures, the item is available and the freight charges are calculated.

2) Module CAT_Products -> Search for a product -> Full Page Edit -> Attributes -> 'Text Options / data-entry forms' -> 'Create New': Name + Title = 'Need By Date' ; Control Type = 'Date Time    Picker' -> 'Add' -> Select this option from the list -> 'Assign'. 
    Module CAT_ItemPaneNF -> Select 'View Options' from the module menu -> select: 'Disable active option management(data-entry forms mode) and show all options and selections. This will  increase the performance'.
    Host -> SQL -> Execute: 'select * from {databaseOwner}CAT_Options', write down the OptionID.
    Host -> SQL -> Execute: 'INSERT INTO {databaseOwner}CAT_ProductsOptions (ProductID, OptionID, Vieworder) Select ProductID, {Your Option ID}, '0' from {databaseOwner}CAT_Products'
    (replace: {Your Option ID} by the option ID)
