hi expert,
i done the same which you mention in earlier form. i manage to change the account group for vendor master.
now there is an another thing came out that is for normal vendor i able to change the account group but there is another vendor which is one time vendor means for vendor i am going to from normal vendor account group to one time account selected account group so in this case when i am changing the group in xk07 the system is saying a following message.
new account group xxx is one-time group: change not permitted.
message no.F2692
so if anybody face the same problem give me your inputs.
thanks in advance,
kk.
