Smart Templates lets you generate XML-based reports that follow the official CADOC structure, exactly as required by the Brazilian Central Bank (BACEN).

This guide walks you through the structure and logic used to generate the CADOC 4111 report in XML.

❗️

Important

These reports follow the COSIF standard and must match the XML structure defined by BACEN. You can adapt the logic to your own data model, but the XML format must be respected.

What is CADOC 4011?

The CADOC 4111 is used to submit daily information about accounting balances, including assets, liabilities, and memorandum accounts, as defined in items I and III of Article 2 of BCB Resolution No. 208, dated March 22, 2022, and BCB Normative Instruction No. 524, dated September 18, 2024.

You’ll use Smart Templates to generate this report in XML, using your own data.

CADOC structure

Base format

The CADOC report must be an XML file and must follow the structure defined by BACEN:

<?xml version="1.0" encoding="UTF-8"?>
<documento codigoDocumento="4111" cnpj="99999999" dataBase="AAAA-MM" tipoRemessa="I">
<contas>
<conta codigoConta="1000000009" saldoDia="99.99" />
<conta codigoConta="1100000002" saldoDia="99.99" />
</contas>
</documento>

Mandatory fields

These fields are required and must be included:

<?xml version="1.0" encoding="UTF-8"?>

Always starts the file. It defines the XML version and encoding so the system knows how to read the content.

<documento> tag

Wraps the entire CADOC structure and includes:

• codigoDocumento: Identifies the type of report which is 4111
• cnpj: Identifies the financial institution.
  • Use only the first 8 digits of the CNPJ (numbers only — no punctuation).
• dataBase: Reporting period, in the "YYYY-MM" format.
  • Example: "2025-01" means January 2025.
• tipoRemessa: Defines the report type:
  • "I" (Inclusion): First submission for that period.
  • "S" (Replacement): Update or correction of previously accepted data.

❗️

Important

If your first submission was rejected due to errors, you still need to use "I" on your next attempt. Only use "S" for replacing previously approved data.

<contas> tag

Groups all account entries for the reporting period.

<conta> tag

• codigoConta: Account code, following COSIF format.
• saldo: Account balance in decimal format (two decimal places).

Using Smart Templates

Each organization can adapt the template to fit its own data model, just replace the placeholder names (like midaz_onboarding.account, midaz_transaction.balance, etc.) to match your structure. The logic stays the same, only the field paths and names change.

Here’s a working example you can use as a starting point:

<documento codigoDocumento="4111"
           cnpj={{ midaz_onboarding.organization.0.legal_document|slice:':8' }}
           dataBase={% date_time "YYYY/MM" %}
           tipoRemessa="I">
  <contas>
    {%- for account in midaz_onboarding.account %}
      {%- with balance = filter(midaz_transaction.balance, "account_id", account.id)[0] %}
        {%- set saldoDia = balance.available | scale:balance.scale %}
        <conta codigoConta="{{ account.id|slice:':10' }}" saldo="{{ saldoDia|floatformat:2 }}"/>
      {% endwith %}
    {% endfor %}
  </contas>
</documento>

Code breakdown

<documento ...>

<documento codigoDocumento="4111"
          cnpj={{ midaz_onboarding.organization.0.legal_document|slice:':8' }}
          dataBase={% date_time "YYYY/MM" %}
          tipoRemessa="I">

Defines the top-level document and required metadata.

codigoDocumento="4111"

Tells BACEN that you're sending a 4111 report.

cnpj={{ midaz_onboarding.organization.0.legal_document|slice:':8' }}

Grabs the first 8 digits of the organization's CNPJ.

• midaz_onboarding.organization.0.legal_document: Grabs the CNPJ from the first organization in the list.
• slice:':8': Trims it to the first 8 digits.

dataBase={% date_time "YYYY/MM" %}

Sets the reporting period dynamically.

• {% date_time "YYYY/MM" %}: Prints the current year and month at render time.

tipoRemessa="I"

Indicates this is a first-time submission (I) or a correction (S).

Account information

    {%- for account in midaz_onboarding.account %}
      {%- with balance = filter(midaz_transaction.balance, "account_id", account.id)[0] %}
        {%- set saldoDia = balance.available | scale:balance.scale %}

{% for account in midaz_onboarding.account %}

Loops through all accounts associated with the midaz_onboarding.account list.

• For each iteration, it creates a new scope where account refers to one specific item in that list.

{% with balance = filter(midaz_transaction.balance, "account_id", account.id)[0] %}

Inside the loop:

• Filters the midaz_transaction.balance by account_id to match the current account's ID.
• [0]: Grabs the first matching balance (assuming there’s only one per account).
• Stores it as a temporary variable balance.

{%- set saldoDia = balance.available | scale:balance.scale %}

• Scales the raw balance to its readable format.
  • Example: 150000 with scale 2 becomes 1500.00.
• The result is stored as saldoDia.

Outputting each <conta /> tag

<conta codigoConta="{{ account.id|slice:':10' }}" saldo="{{ saldoDia|floatformat:2 }}"/>

Creates one <conta> element per account, with two attributes:

• codigoConta="{{ account.id|slice:':10' }}": Uses the first 10 characters of the account ID; useful if the full ID is too long or the integration expects a fixed length.
• saldo="{{ saldoDia|floatformat:2 }}": Formats the balance with exactly two decimal places.

❗️

Important

Always apply scaling before rendering numeric values to ensure accuracy. Use floatformat:2 to enforce two decimal places.

Closing the template

  </contas>
</documento>

Wraps up the account list and document structure.

Rendered example

Here’s how the final XML might look after rendering:

<?xml version="1.0" encoding="UTF-8"?>
<documento codigoDocumento="4111" cnpj= 78425230 dataBase=2025/06 tipoRemessa="I" >
	<contas>
		<conta codigoConta="0196d9758" saldoDia= "-2500000.00" />
		<conta codigoConta="0196d9720" saldoDia= "499950.00" />
		<conta codigoConta="0196d9761" saldoDia= "500050.00" />
		<conta codigoConta="0196d9779" saldoDia= "500000.00" />
		<conta codigoConta="0196d9797" saldoDia= "500000.00" />
		<conta codigoConta="0196d9725" saldoDia= "500000.00" />
		</contas>
	</documento>

Customizing the template

Feel free to adjust the placeholder names (like midaz_onboarding.account) to match your own data model. Just make sure to preserve the XML structure, that’s what ensures BACEN will accept your file.

🚧

Attention

Always validate the rendered XML against BACEN’s schema before submitting.
The structure alone isn’t enough, the data must reflect your institution’s actual ledger.
