# Log a complaint

> Capture, classify, and manage a product complaint through to closure.

## The Complaint Register

All complaints are listed with type/subtype, product/lot, site, severity, status, and date received.
A consistent complaint process matters to regulators — they look at how you capture, classify,
investigate, and resolve complaints. Review the register regularly so complaints don't stall.

## Set up your taxonomy (once)

Before logging complaints, define your controlled taxonomy on **Complaints → Taxonomy**: add complaint
**types** (for example, Packaging, Product quality, Distribution) and a set of **subtypes** under each.
Classifying against a controlled taxonomy — rather than free text — is what makes your complaint trends
consistent and reportable.

## Create the complaint

1. Go to **Complaints → New complaint**.
2. Record the source channel, product/lot, and site.
3. Capture the complainant details (or mark the complaint anonymous).
4. Classify it against your taxonomy (type → subtype) and set the severity.
5. Save. The complaint is created and the creation is captured in the audit trail.

## Investigate and link corrective action

These actions require Complaints to be enabled and the relevant permission for your role.

1. Select **Start investigation**. Wait for the request to finish before another action.
2. Open **Link disposition**, or **Raise required CAPA** if the complaint requires a CAPA.
3. To reuse an existing record, select **Attach existing records** and choose by number and title from
   the deviation and CAPA pickers. Only the current organization's available records are offered.
4. Otherwise, complete the linked-record creation fields in the dialog.
5. Submit and confirm that the selected disposition appears on the complaint.

A failed action shows its own error. Review the message and record state before retrying; opening
another dialog does not carry the old error into that action.

## Close the complaint

Record a resolution summary and move the complaint to closed. Every state change is written to the
tamper-evident audit trail automatically.

  This guide reflects what is built today: intake, controlled taxonomy, complaint-to-CAPA linkage, and
  severity/status tracking to closure.
