Hello all,
I'm trying to "generate opening entries" in the accounting->Periodic processing->End of period menu.

I get this error. This error is launched by the account_constraints module.

Here is the error I get :

You cannot do this on an entry generated by a bank statement. 
You must change the related bank statement directly.
Bank statement name (id): Square - PT - novembre 2015 (1185).         

Could you help please?
