Duplicating Crystal Layouts to another document type

Experts,

I'm created a Invoice layout that I'll use as a default for all AR Layouts. I will use this to copy to Sales Order ext.

When I used the 'Duplicate Layout Template' functionality in B1, I got no errors.

• Issue No. 1: But when I previewed this layout in the Sales Order, I first had to enter a "ExtParam" parameter field as "N" or "Y" before this showed the Sales Order.
• Issue No. 2: Every thing looks good on the SO, except that it is named 'Invoice' at the top and subtotals.

How can I correct this in order to copy one layout to another document type?

Regards,

Marli
