Normalize multi-currency amounts to a reporting currency with as-of rates
- When reports mix currencies because each source system stored whatever rate it had on hand.
- When a balance sheet and a P&L for the same period use two different exchange rates for the same currency.
Convert multi-currency amounts to a reporting currency using as-of, period-average and closing rates depending on the statement, with a daily FX dimension that fills forward across non-trading days. Delivers the conversion and its rate dimension; sourcing new rate feeds beyond the stated source is a separate outcome.
Sample This Recipe has not been materialized in the Cookbook repository yet. Its trigger, description, prompt, agent guidance and acceptance conditions, and the explanation below, are prototype drafts. Its name, job, area and readiness come from the reconciled Cookbook seed snapshot. Readiness is a separate question from this one: it says whether the capability exists, not whether the writing has been reviewed.

What has to be observably true before this Recipe is finished.
- every converted row carries a rate; none are left unconverted
- a balance sheet uses the closing rate and a P&L uses the period-average rate for the same period
- a non-trading day's rate matches the most recent prior trading day
- rounding differences stay within the agreed tolerance on a reconciled sample
Recipe promptThe task specification the agent reads. Reference only — it is not what you copy.
Deliver: Normalize multi-currency amounts to a reporting currency with as-of rates. Convert multi-currency amounts to a reporting currency using as-of, period-average and closing rates depending on the statement, with a daily FX dimension that fills forward across non-trading days. Delivers the conversion and its rate dimension; sourcing new rate feeds beyond the stated source is a separate outcome. Execute inside the current Intent. Its Domain, repository, platform, environment and attached sources are the context for this work — read them rather than asking for them. The work is done when: - every converted row carries a rate; none are left unconverted - a balance sheet uses the closing rate and a P&L uses the period-average rate for the same period - a non-trading day's rate matches the most recent prior trading day - rounding differences stay within the agreed tolerance on a reconciled sample Report the evidence for each condition above with the result. A condition you cannot meet is something to say, not something to work around.
Agent guidanceHow the agent approaches the work, and what it will not do.
Profile the inputs the grain, joins and measures actually depend on before proposing a model. Put the design up for review — grain first — then build in an isolated copy with tests and documentation landing beside the model rather than after it.
Composes
- dbt model authoring and layering
- dbt in the project
- dlt in the project
- isolated-copy execution and gate verification
Asks first
Semantic decisions the Intent cannot supply. Never context Studio already holds.
- which Fabric target this work lands on, when the Domain carries both a Lakehouse and a Warehouse
Guardrails
- Build in an isolated copy. Production is read, never written.
What you need
- Microsoft Fabric Lakehouse, Microsoft Fabric Warehouse, MotherDuck, or DuckDB.
- A dbt project you can build, and read access to the models it starts from.
- dbt and dlt in the project, or the intent to add it.
- Needs a source of record for rates.
How it goes
- State the outcome in one sentence, in the language the request arrived in.
- Let it profile the inputs the grain, the joins and the measures actually depend on.
- Review the design. Disagreeing about grain here costs a sentence; after the model exists it costs a rewrite.
- Let it build in an isolated copy, with the tests and the documentation landing beside the model rather than after it.
- Read the acceptance conditions against the run.
What you end up with
The deliverable, in your own repository, as transformation work a reviewer who knows the project reads as native to it. Alongside it, the evidence for every one of the acceptance conditions above — which is the part that is still there in three weeks when somebody asks.
