I have one GL a/c which s a balance sheet ac and I made postings to this GL ac.Now I want to activate Openitem Management functionality on this a/c.
While changing this GL a/c to put OpenitemManagement check,it is not allowing me to save.It is throwing below error message.
You cannot change the open item management setting; (see long text)
Message no. FH087
This account does not have a balance of zero.
You cannot activate/deactivate open item management with this transaction.
If you want to activate open item management retroactively for an account, create a new account with the correct setting and transfer the existing items to this account.
If you want to deactivate open item management retroactively for an account, clear all the postings on this account first. Now you can change the setting for open item management
Please advise how to change GL a/c to openitem managemet.
Thanks & Regards
