A trigger condition that is false does not start a run and does not leave run history. How the expression differs from a Condition action, and how to see the skipped checks.
Dataverse's filtered record ownership (preview) secures rows by column values such as region or department instead of owner or business unit. How record filters, entity record filters, and security roles fit together, and what the no-owner model gives up.
What matters in Microsoft's September 2026 Power Platform feature update: the model app-builder skill goes GA, the canvas authoring agent plugin goes GA, generative pages embed in forms and reach connectors, model-driven header refresh is GA with display density in preview, and Power Automate gets server-side search.
Load independent Dataverse and SharePoint calls together in a canvas app, and keep the calls that really do depend on each other out of the same Concurrent.
How Select columns and Filter rows on a Dataverse trigger cut wasted runs, and the row-version mistakes that make a flow miss the change it was built for.
Delegation limits, relationships, security, and ALM — the practical tradeoffs when a canvas app outgrows a list and when it should not migrate at all.
What Dataverse elastic tables are, how TTL, partitioning, and JSON columns work, and how to decide between elastic and standard tables.
How Power Automate retry policies work, which errors they cover, how to configure them, and how to keep retries from duplicating side effects.

Transient failures are normal in any flow that calls an API. The difference between a flow that self-heals and one that pages you at 2 a.m. is how you handle retries and the failures that stick.
