# Reset and empty SetLoadFields restore a full-row load
> Contributions welcome — open a PR to refine or extend this article.
## Description
`SetLoadFields(...)` sticks to the record variable until something clears it. `Reset()` "changes fields select for loading back to all", and `SetLoadFields()` with no arguments does the same. A later `FindSet` or `Get` then materializes every normal field. Agents often place `SetLoadFields` first, then `Reset` to apply new filters, and assume the partial selection survives. It does not.
## Best Practice
Call `Reset` (or empty `SetLoadFields()`) first when the variable must be reused, then call `SetLoadFields` with the fields the next read actually uses, then apply filters and read. After `Reset`, a new `SetLoadFields` is required; the previous list is gone.
See sample: `reset-clears-partial-record-selection.good.al`.
## Anti Pattern
`SetLoadFields(...)` followed by `Reset()` (or by parameterless `SetLoadFields()`) and then `FindSet` without restoring the load list. The filters look correct; the SQL still selects every column.
See sample: `reset-clears-partial-record-selection.bad.al`.
