Pasting into P4210 Grid Lines

In an attempt to accelerate sales order data entry, we are exploring the use of the Internet (off of JDE) for our remote sales force to do their own keystroking. The resulting data records will be copied (from Excel) and pasted into the Grid Lines of P4210 (simply a quantity and a SKU number).

P4210 seems to parse all of the information correctly and adds pricing, flags availability and seems to do all error correcting properly. Are there any issues with a copy/paste into Grid Lines? It seems like a no-brainer, and should save a tremendous amount of time.

We've recently gone live, and we're a little anxious working "outside" of the system.

Thanks for your advice.
