LUSID comes with a set of built-in break codes for your use in reviewing reconciliation results. You can create your own reconciliation break codes using the LUSID web app.

To do this:

Navigate to Reconciliations > Configuration and select the Break codes tab.
Click Create break code.
Specify a unique Code and a friendly Description.
Click Create to save your new break code.

Provided your reconciliation definition is configured with the correct break code source (see note below), you can subsequently select your break code when you review and manage breaks. Read more.

Note
Break codes you create in the LUSID web app are stored within a particular source. If using the CreateGroupReconciliationDefinition API to create reconciliation definitions, you must use the following breakCodeSource value to be able to use any new break codes you create:
"breakCodeSource": {
    "dataTypeId": {
      "scope": "reconciliations",
      "code": "break-codes"
    }
  }
Note LUSID sets this value automatically when you create a reconciliation definition via the LUSID web app.
