No Gl account determination when copying from an old SC .

Dear All

When I am creating a new SC and chossing a Category the Gl accoutn gets populated from the BBP_DET_account table which is the standard behaviour and correct.

Now , if there is a change in bbp_det_account setting and I copy from the cart which was created before this change then in the New SC which was copied I still get the Gl account as the old one .

For example :

SC #

category

G/L Account

1001000866

B107

72731200

1001000828

M301

74310000

1000183622

B107

72720000

Created SC 1001000901 by copying 1001000866 and changed category to M301 > GL account 74310000 ---SUCCESS --- HERE THE REFRESH TAKES place succesfully ..

Created SC 1001000905 by Copying 1000183622 and GL account is the old Gl account 72720000 ---- ERROR

PLEASE CAN SOME ONE GUIDE ME on how to put a refresh of Gl account when the SC is copied ... !
