# Tag executions with Execution Data in Duaer

In Duaer, Execution Data defaults to Operation Save Highlight Data (for Search/review). Under Data to Save, add Key and Value pairs for the executions list and filters.
## Save two highlight fields

1. Search for Execution Data and connect it where the run should record context.
2. Leave Operation on Save Highlight Data (for Search/review).
3. Under Data to Save, select Add Saved Field.
4. Set Key, for example orderId. Set Value to text or an expression.
5. Select Execute step. The highlight data appears on that execution.

Keys longer than 50 characters and values longer than 512 characters are truncated.

Filtering executions by highlight data needs a plan that includes it. See product pricing.
## Questions

### Does Execution Data in Duaer rewrite downstream json?

It mainly stores key/value pairs as searchable highlight data on the execution. Items still pass through. Do not treat it as Edit Fields.
