2. In Odoo 16, the sequence number is a field used to assign a
unique, incremental number to records in a specific model. It
helps in maintaining the order or sequence of records and can be
useful in various scenarios.
3. Here are some common use cases of sequence number:
• Order and Ranking: Sequence numbers can be used to establish a specific order or ranking for records within a model. For
example, in a list of tasks, the sequence number can determine the priority or order in which the tasks should be executed.
• Document Numbering: Sequence numbers are commonly used to generate unique document numbers, such as invoices,
purchase orders, sales orders, etc. Each time a new record is created, the sequence number field is automatically assigned a
new, sequential value.
• Sorting and Filtering: The sequence number field can be used for sorting and filtering records. By sorting records based on the
sequence number, you can view them in a specific order, such as ascending or descending.
• Workflow and Automation: Sequence numbers can be leveraged in workflow and automation rules. For example, you can
define specific actions or triggers based on the sequence number of a record, allowing you to automate certain processes or
notifications.
• Reference and Identification: Sequence numbers can serve as a reference or identification for records. They provide a unique
identifier that can be used to easily locate or reference specific records within a model.
4. Let's talk about how to create a sequence number in Odoo 16 using Python and XML.
• As seen in the image below, first we need to define a field for the sequence.
• Then we need to define a function for creating sequence in the particular model.
5. • And after that, make an XML file and create record for that.
6. Let’s discuss each item in the XML file.
• The ID is the ID of that record, it is unique for each record. And that record will be stored in the ir.sequence table.
• name - is the Name of the record that will be created on the specified model.
• Code - is the sequence code for the record.
• Prefix - is a character field that gives the prefix of the sequence for the record.
• Padding - is the size of the sequence. We can decide the size.
• Active- It determines whether the sequence is currently active or not.
• Number Next - The number_next field determines the value of the next sequence number to be generated.
• Number Increment - The number_increment field determines the amount by which the sequence number increases with each new
number generated.
8. In the above screenshot we can see a sequence number is generated with a prefix of IN and the
number is 0001 the first number is automatically generated as 1 and we create another record
in the same model that will be 2 and so on and also here we can see the padding of the number
is 4 that we will mentioned in the code.
9. Also we can configure the sequence number from the general setting of Odoo,
• Go to the "Settings" menu and select "Technical" -> "Sequences & Identifiers" -> "Sequences."
• Click the "Create" button to create a new sequence.
• Enter a name for the sequence, such as "Your Model."
• Enter a code for the sequence, such as "your.model."
• Choose a prefix and/or suffix for the sequence, if desired.
• Set the "Next Number" field to the starting number for the sequence.
• Set the "Padding" field to the number of digits you want the sequence number to have.
• Select the "Implementation" option for the sequence, such as "Manual," "Date Range," or "Custom."
• Save the sequence by clicking the "Save" button.
• Use the sequence in your Odoo application by referencing it in your code or by using it in your forms and reports.
