I found this very instructive entry.
My use case seems similar, but a little different: I have invoices, credit notes and payments to reconcile. account_statement module is installed.
Can I use the Wizard under Financial > Payments > Lines to pay as well for this? I did not find a possibility to select lines at the ‘payable’ and the ‘receivable’ side at the same time.
Thanks a lot in advance,
EG
If you want to use the account_statement module the easies is to create a line with the amount paid by the party and then use the reconcile wizard to reconcile all the related documents.
Thank you for your time and effort.
My guess is:
I’d create that payment at Financial > Payments > Receivable Payments - correct ? - But I cannot select any of my journals, none is offered. Which type of journal do I have to use?
And yet another questions:
Do I have to use the general reconcile wizard and cycle through all other Parties, or is there a way to just select that specific party?
EG
NO, you should use statement journals: Design — Account statement for Tryton
Payments are just for creating payable or receivable requests but do not create any accounting moves. Statements are use to book the payments in accounting.
From the party model you have a relate to open its “Payable/Receivable Lines”. From there you can manually reconcile the lines of such party using the Reconcile action.
Yes, that’s what I thought. Mine looks like this:
What could be wrong with it, so I cannot select it at Financial > Payments > Receivable Payments ?
Oh, I ever and ever again forget about how powerful this tiny link menu is, especially at the party. Yes, it’s very obvious that individual reconciliations can be made there. Thank you for your patience.

This is normal Journal but not statement Journal. Statment Jounral is under:
Financial -> Configuration -> Statement -> Journals
I don’t have a separate menu entry “statement” under "configuration. So I guess, there should be a section “statement” at the configuration sheet, but it is not.
Do I need another module? “account_payment” is in place.
EG
Yes, you need to activate the account_statement module.
Yes, it’s active as well.
Then you should check your user has the “Account Statement” group. Otherwise it won’t be allowed to see such menu option.
You just need to be in “Accounting Administration” group to get access to the configuration of statements.
