Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Data Policy on sc_req_item
Why it's wrong here
Data policies do not directly evaluate complex JSON structures inside multi-row variable sets.
- ✗
Dictionary Overrides
Why it's wrong here
Dictionary overrides modify field attributes on extended tables, not MRVS validation.
- ✓
Catalog Client Script (onSubmit)
Why this is correct
Catalog Client Scripts with an 'onSubmit' type can access and validate Multi-Row Variable Set data before form submission.

Why it's wrong here
