Error occurred while validating the field(s) line_id: You cannot create entries on different periods/journals in the same move

[Seema Nagar]

Hi All,

I was trying to reconcile the sundry debtor account ,when
I got the error :
"Error occurred while validating the field(s) line_id: You cannot create entries
on different periods/journals in the same move"

I am using openerp stable version 6.0.1
on Ubuntu.

Steps I Followed are :

I tried to reconcile the invoice entry in the system
with the payment entry of the same.

Invoice entry details :
Amt : 105654 Rs
Effective date : 18/04/2011
Period : 04/2011
Creation date of customer invoice : 23/05/2011

Payment Entry details :
Amt : 103052
Effective date : 19/04/2011
Period : 04/2011
Creation date of client payment voucher : 23/08/2011

I selected the these 2 entries and tried to reconcile with write-off.
During that I entered the details below :
Write off journal : Write - off
Write-off account : Exchange Fluctuation
Date : 23/08/2011
When I Click on Reconcile button I get
the Warning :
"Error occurred while validating the field(s) line_id: You cannot create entries
on different periods/journals in the same move"

Due to this I am unable to reconcile my client account,
and to let the invoice be updated as paid.

I have many times done the sundry debtor reconciliation , but never got
such error message .

I am unable to figure out, what could be the reason I am facing
this error. Is it due to some date constraint on entries ?

Thanks and Awaiting your reply.
