# Manage Material Time Constraints

Creates, updates, and removes explicitly selected time constraints for one **Material** through the manufacturing service.

## Inputs

Set `Material`, `ToAdd`, `ToUpdate`, `ToRemove` in the task details. Use the value editor to select compatible results from earlier tasks.

## Outputs

Use `Material`, `Constraints`, `AddedCount`, `UpdatedCount`, `RemovedCount` in subsequent tasks.

??? example "Manage Material Time Constraints"

    Connect the **Material** and the native collections selected for `ToAdd`, `ToUpdate`, and `ToRemove`. Leave unused collections empty; unrelated constraints are preserved.
