Puoi usare account_analytic_plans
Io personalmente non lo uso, perchè disabilita la gestione dei conti analitici manuale
La documentazione del modulo dice così:
This module allows to use several analytic plans, according to the general journal.
===================================================================================
Here multiple analytic lines are created when the invoice or the entries
are confirmed.
For example, you can define the following analytic structure:
Projects
Project 1
SubProj 1.1
SubProj 1.2
Project 2
Salesman
Eric
Fabien
Here, we have two plans: Projects and Salesman. An invoice line must
be able to write analytic entries in the 2 plans: SubProj 1.1 and
Fabien. The amount can also be split. The following example is for
an invoice that touches the two subproject and assigned to one salesman:
Plan1:
SubProject 1.1 : 50%
SubProject 1.2 : 50%
Plan2:
Eric: 100%
So when this line of invoice will be confirmed, it will generate 3 analytic lines,
for one account entry.
The analytic plan validates the minimum and maximum percentage at the time of creation
of distribution models.
