Errro in MIGO - Account determination for entry CIPL BSX 0001 ___ 7904 not

Hi,

I have created a new Valuation Class (7904). While doing the MIRO the following error is encountered:

Account determination for entry CIPL BSX 0001 ___ 7904 not possible.

The error is most probably due to the G/L Account. Pls. let me know how can I assign the G/L Code to the newly created Valuation Class.

Regards
