error related to cosr element tcode f-43

Hi finance experts,

while i was trying to post a vendor invoice to certain gl account (conveyance-sales) i am getting an error after entering this particular account number as

' create account XXXXXXXXXX for dd.mm.yyyy as a cost element in controlling area ZZZ '

where

XXXXXXXXXX= gl account no conveyance-sales

ZZZ= our only controlling area ,it has same characters as our company code.

where as i am not getting this error for some other accounts like fare for travel,postage ....

what are the possible causes of error,is it something related to cost center.

thanks in advance
