Before you register any sale, purchase any products, or do anything finance relevant, we suggest that you setup accounting first. Even if you are not managing your finance and accounting in Odoo, we would still recommend that for basic correctness of transactions for billing/purchasing, you setup accounting with a bare minimum Chart of Account, define Currencies etc.
This section only tries to cover the bare minimum configuration for getting Odoo setup and functional with Bahmni systems, for comprehensive guide, you should follow the step by step guide given by Odoo Accounting module to setup for your implementation.
You need to setup accounting to reflect your implementation and appropriate to your country's regulations/schedules. Bahmni demonstration websites has the accounting configured by means of an addon app (India - Schedule VI accounting).
As explained above, if you have installed a local accounting module, it will setup sensible default, but you should make sure that the COA reflects your implementation needs.
Odoo accounting by default does not provide a hierarchical CoA. If you need a hierarchy of accounts, look for so, in the Odoo website / app store. For example: This module provides a simple CoA Hierarchy, but does not provide a view or report as such. This module needs to be downloaded and installed the same way 'Web preview' module was installed, as explained in the System Configuration page, see section "Installing add-on Apps or Modules"
Go to "Menu / Accounting / Configuration / Settings"
Go to "Menu / Accounting / Settings"
If you would like to give discounts, you would probably want to configure accounts specific for discounts
Go to "Menu / Accounting / Chart of Accounts /" and click create
If you have installed an app that supports hierarchy, you may want to configure specific discount accounts, like below
