Juornal Entry description

   Hi,

     When i post my invoices from Payables to GL, how is it possible that the invoice lines description are also transferred to the GL Journal?
    For example:
    In my invoice distribution lines, i entered an invoice line dscription 'Purchase of computers'
    When i do Create Accounting and Final Post to GL, this description should also be transferred in the GL Journal Header/Line description.

    Can this be done in SLA.
     How can it be done?

    Appreciate all help.

   Thanks!
