Reconciliation account creation

Hi all,

While I am trying to create a vendor master, in accounting tab when I wish to input reconciliation account the system prompts the message no reconciliation accnt can be given .Then while I am trying to create Reconciliation account in FS01 the system prompts message "No corporate account is defined for chart of accounts".

Plz suggest what to do .I am using IDES 800 ,INT chart of account.

Regards

Abhijit
