Vendor Master - Recon Account

Hi,

The users, while creating the Vendor Masters, used a particular Recon Account. Thereafter the entries were posted to this account and subsequently it was found that the Recon A/c was wrongly mapped. The users tried to use the T Code for 'Change Master' but the system does not allow to change the Recon Account. Is there some other way out as to how could the Recon A/c be changed now. Could you please advise ?

Thnx in advance.
