Change a GR/IR account in a reconciliation account

Dears,

my customer has a request: he wants to change a GR/IR account in a reconciliation account. Currently this account has this settings: - open item management - only balance in local currency- post automatically only.

In order to set upthis account as a reconciliation account I should:

- clear the open item

-bring to zero the balance

- make the change in the account master data

I 've checked that is not possible clear manually a GR/IR account.

Has someone faced a similar issue? Is it possible performe this activity?

Thanks in advance

Vittoria
