[Erp5-users] default_invoice_transaction_rule predicates

[Vera Kurpas]

Hello!
Could you please check my assumptions?
Using the default_invoice_transaction_rule the predicates are assigned.
Then the debit and credit accounts are set in Accounting Rule Cells. So
the predicates give the conditions describing movements which are the
basis for Transactions indicated in Accounting Rule Cells. 

Usually the Sales and Purchase operations are reflected by different
account transactions. I don't know how the difference between Sale and
Purchase movement (delivery?) should be described in predicates? Could
you please help?

Thanks,
Vera Kurpas
