Custom reports¶
Odoo comes with a powerful and easy-to-use reporting framework. The engine allows you to create new reports, such as tax reports, balance sheets, and income statements with specific groupings and layouts.
Important
Activate the developer mode to access the accounting report configuration.
To create a new report, go to root report or a variant.
. From here, create either aAstuce
Consider saving modified reports as report variants to keep their root reports intact.
To access an existing report’s management interface from the report itself, click on the (gears) icon.
Root reports¶
Root reports can be regarded as generic, neutral accounting reports. They serve as models on which local accounting versions are built. If a report has no root report, it is considered to be a root report itself.
Example
A tax report for Belgium and the US would both use the same generic version as a base and adapt it for their domestic regulations.
Creating a menu item is required to access a new root report. To do so, open the report’s configuration, click Action, Create Menu Item, and refresh the page. The report is now available under .
Note
Cases that require creating a new root report are rare, such as when a country’s tax authorities require a new and specific type of report.
Variants¶
Variants are country-specific versions of root reports and, therefore, always refer to a root report. To create a variant, select a generic (root) report in the Root Report field when creating a new report.
When a root report is opened from the Accounting app’s Reporting menu, all of its variants are displayed in the report variant selector in the top right corner of the view.
Example
VAT Report (BE) is a variant of the root Generic Tax report.

Lines¶
After creating a report (either root or variant), the next step is to fill it with lines. To create a new line, click on Add a line. To modify an existing line, click on the line itself and edit the popup. All lines require a Name and can have an optional Code which allows using the line’s value in formulas.

Expressions¶
Each line can contain one or multiple expressions. Expressions can be seen as sub-variables needed by a report line. To create an expression, click on Add a line within a line’s popup.
When creating an expression, you must enter a Label used to refer to that expression. The label must be unique among the expressions of each report line. Both the Computation Engine and the Formula fields must also be completed. The computation engine defines how the formula(s) and subformula(s) are interpreted. It is possible to mix expressions using different computation engines under the same line if needed.
Note
Depending on the engine, subformulas may also be required.
Odoo Domain computation engine¶
When using the Odoo Domain computation engine, a formula is interpreted as an Odoo
domain targeting account.move.line
objects.
The subformula allows you to define how the move lines matching the domain are used to compute the value of the expression:
sum
The result is the sum of all the balances of the matched move lines.
sum_if_pos
The result is the sum of all the balances of the matched move lines if this amount is positive. Otherwise, it is
0
.sum_if_neg
The result is the sum of all the balances of the matched move lines if this amount is negative. Otherwise, it is
0
.count_rows
The result is the number of sub-lines of this expression. If the parent line has a group-by value, this will correspond to the number of distinct grouping keys in the matched move lines. Otherwise, it will be the number of matched move lines.
Astuce
To reverse the sign of the result, put a -
sign at the beginning of the subformula.

Aggregate Other Formulas computation engine¶
The Aggregate Other Formulas computation engine performs arithmetic operations on the
amounts obtained from other expressions. Formulas here are composed of references to expressions
separated by one of the four basic arithmetic operators (addition +
, subtraction -
, division
/
, and multiplication *
). To refer to an expression, type in its parent line’s code followed
by a period .
and the expression’s label (ex. code.label).
Subformulas can be one of the following:
if_above(CUR(amount))
The value of the arithmetic expression will be returned only if it is greater than the provided bound. Otherwise, the result will be
0
.if_below(CUR(amount))
The value of the arithmetic expression will be returned only if it is lower than the provided bound. Otherwise, the result will be
0
.if_between(CUR1(amount1), CUR2(amount2))
The value of the arithmetic expression will be returned only if it is strictly between the provided bounds. Otherwise, it will be brought back to the closest bound.
if_other_expr_above(LINE_CODE.EXPRESSION_LABEL, CUR(amount))
The value of the arithmetic expression will be returned only if the value of the expression denoted by the provided line code and expression label is greater than the provided bound. Otherwise, the result will be
0
.if_other_expr_below(LINE_CODE.EXPRESSION_LABEL, CUR(amount))
The value of the arithmetic expression will be returned only if the value of the expression denoted by the provided line code and expression label is lower than the provided bound. Otherwise, the result will be
0
.
CUR
is the currency code in capital letters, and amount
is the amount of the bound expressed in
that currency.
You can also use the cross_report
subformula to match an expression found in another report.
Prefix of Account Codes computation engine¶
The Prefix of Account Codes computation engine is used to match amounts made on accounts using the prefixes of these accounts” codes as variables in an arithmetic expression.
Example
21
Example
21 + 10 - 5
21
and 10
, and subtracts the balance of the ones on accounts with the prefix 5
.It is also possible to ignore a selection of sub-prefixes.
Example
21 + 10\(101, 102) - 5\(57)
101
, 102
,
and 57
.You can apply “sub-filtering” on credits and debits using the C
and D
suffixes. In this
case, an account will only be considered if its prefix matches, and if the total balance of the
move lines made on this account is credit/debit.
Example
Account 210001
has a balance of -42 and account 210002
has a balance of 25. The formula
21D
only matches the account 210002
, and hence returns 25. 210001
is not matched, as its
balance is credit.
Prefix exclusions can be mixed with the C
and D
suffixes.
Example
21D + 10\(101, 102)C - 5\(57)
21
if it is debit (D
) and 10
if it is credit (C
), but ignores prefixes 101
, 102
, and
subtracts the balance of the ones on accounts with the prefix 5
, ignoring the prefix 57
.To match the letter C
or D
in a prefix and not use it as a suffix, use an empty exclusion ()
.
Example
21D\()
21D
, regardless of their balance sign.In addition to using code prefixes to include accounts, you can also match them with account tags. This is especially useful, for example, if your country lacks a standardized chart of accounts, where the same prefix might be used for different purposes across companies.
Example
tag(25)
If the tag you reference is defined in a data file, an XMLID can be used instead of the ID.
Example
tag(my_module.my_tag)
You can also use arithmetic expressions with tags, possibly combining them with prefix selections.
Example
tag(my_module.my_tag) + tag(42) + 10
10
C
and D
suffixes can be used in the same way with tags.
Example
tag(my_module.my_tag)C
Prefix exclusion also works with tags.
Example
tag(my_module.my_tag)\(10)
10
.External Value computation engine¶
The External Value computation engine is used to refer to manual and carryover
values. Those values are not stored using account.move.line
, but with
account.report.external.value
. Each of these objects directly points to the expression it impacts,
so very little needs to be done about their selection here.
Formulas can be one of the following:
sum
If the result must be the sum of all the external values in the period.
most_recent
If the result must be the value of the latest external value in the period.
In addition, subformulas can be used in two ways:
rounding=X
Replacing
X
with a number instructs to round the amount to X decimals.editable
Indicates this expression can be edited manually, triggering the display of an icon in the report, allowing the user to perform this action.
Note
Manual values are created at the date_to
currently selected in the report.
Both subformulas can be mixed by separating them with a ;
.
Example
editable;rounding=2
Custom Python Function computation engine¶
The Custom Python Function computation engine is a means for developers to introduce custom computation of expressions on a case-by-case basis. The Formula is the name of a python function to call, and the Subformula is a key to fetch in the dictionary returned by this function. Use this computation engine only if making a custom module.
Columns¶
Reports can have an indefinite number of columns to display. Each column gets its values from the expressions declared on the lines. The field expression_label of the column gives the label of the expressions whose value is displayed. If a line has no expression in that field, then nothing is displayed for it in this column. If multiple columns are required, you must use different expression labels.

When using the period comparison feature found under the Options tab of an accounting report, all columns are repeated in and for each period.
Line grouping¶
Non-standard grouping is possible by adding or using existing fields on the Journal Item model, provided that the fields are related and non-stored.
Note
Grouping lines requires the report to have explicit report lines that can be edited. The deferred reports, for example, do not support grouping lines as they use dynamic lines that are generated.
Create a new field on journal item¶
To create a non-stored, related field in the Journal Item model, first go to (bug) icon, then click Fields. Click New to create a new field, and complete the following fields:
, and click theField Name: a technical name for the field
Field Label: the label to be displayed for the field
Field Type: the type of field that this related field should point to
Stored: Leave this field unchecked as only non-stored fields can be used to group lines.
Related Model: If the field type is one2many, many2many, or many2one, select the model of the original field to group by.
Related Field Definition: the technical path to the field you want to group by
Example
To group by the sales team of the commercial partner, set the related field definition to
move_id.team_id
.
Group lines¶
To group lines, go to the Lines tab of the desired report, click on the line you want to group, and edit the Group by field. Enter the technical name (Field Name) of the field to use as the grouping key.
Astuce
To find a list of all the model’s fields and their technical names, go to (bug) icon, then click Fields. The technical name of each field is listed in the Field Name column.
