Change the Recon Account Type

Hi,

The users are trying to post the entry into a GL Account directly using the T Code FB50. However, the system gives the error message -

"Account XXX in Company Code XXX is marked as a reconciliation account for account type "D" and cannot therefore be directly posted."

When we check the GL Master using the T Code FS00, we find that the GL Code has not been marked for automatic posting. Could you please advise as to how can we change the Account Type from Recon to non Recon type. This GL Code is not intended by the users for any of the Subsidiary accounts such as Vendors/Customers.

Thanks in advance.

Regards
