Yes, I now understand that to be the case. My reason for writing is manifold.
Early on I was misled. Possibly by myself or discussions on the forum, I don't recall.
To believe that the only way to maintain an unique SKU was to define each product separately.
It also seemed that I was not the only one.
If the SKU field were made configurable like the options than one could enter ALL the variables at once when initially defining a new product. Than in "manage options" where all the possible iterations are displayed you could choose to display the ones currently available. All done. One simple operation. Unique SKUs in place. Inventory controlled.
Because the SKU needs to be replaced for each variation of a product you need to make the trip through this process repeatedly. Eats up a lot of time.
If I'm not being clear enough - and I don't think I am - please contact me directly and I can walk you through the process I'm trying to describe.
And Ray, can you comment on the first and third questions I posed in my previous post?
