Power BI is where many finance and supply-chain teams read their numbers. Lima triggers a semantic model refresh when a load completes so dashboards show the new data, or lands Delta tables in Fabric so Power BI reads them through Direct Lake without an import.
Each method has a job. The first load uses the bulk method; the daily run uses the incremental or change-capture method; write-back uses the interface the system itself uses.
| Method | What it does | When it is used |
|---|---|---|
| Refresh trigger | Calls the Power BI REST API to refresh a model after a load. | Import models. |
| Direct Lake via Fabric | Lands V-Ordered Delta tables. | Fabric estates. |
The objects are the tables, views or records Lima reaches through the methods above. The patterns say how a copy is made and kept current.

The prerequisites are what the team that runs Microsoft Power BI grants. The four steps are the same for every connector.
Incoming data = valid records + exception records. A row that fails a check is kept, routed to the person who owns it with a deadline, and replayed once fixed. The load carries on with the valid rows and the report says exactly what was held back. How exceptions work →
Lima connects from outside through the interfaces listed above with credentials your administrators grant. Where a vendor requires its own agent or add-on for a method, the prerequisites say so.
Parallel reads are capped and the cap is agreed with the team that runs the system. Large reads run inside an agreed run window. Change capture keeps the daily volume small.
A report per run: rows in, rows out, control totals and variance per table, the exceptions held back and who owns them, and whether the deadline was met.
Yes. Most estates start with one source, one target and one dataset, then add tables and patterns on the same connection.
A trial connects this system, runs a first load and ends with a reconciliation report. Your administrators see the prerequisites before anything is installed.
