Copy & Paste data in transaction launcher

Hi,

I am beginner of CRM. My requirement is create sales documents in transaction launcher from CRM to R3 transactions (VA21, VA01) although not be the best practice ,  I need to copy several cells from excel and paste them in the transaction launcher, but all the elements was copied inside the first cell in quotation. Could you please give a clue? / Do you think that is a limitation of the standard WEB UI?

1. Copy cells from Excel document.

     2. Paste cells to quotation of the transaction luncher

** The elements only was copied in the first cell in quotation.

     3.- From R3 in the tcode VA01, work fine

Best Regards
