CIS-ITSM Service Catalog And Request Management Practice Question
An administrator created a Multi-Row Variable Set (MRVS) and wants to populate a field on the target task using the data collected in the MRVS rows. Since MRVS stores data as a JSON string, what is the best way to extract and process this data in a workflow script?
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Parse the JSON string using JSON.parse(current.variables.mrvs_name) in a Run Script activity and iterate through the resulting array.
Using JavaScript's JSON.parse() on current.variables.mrvs_variable_name allows iterating through the array of objects in a workflow script.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Dot-walk directly to current.variables.mrvs_name.column_name in the task activity.
Why it's wrong here
Dot-walking directly to columns in an MRVS fails because MRVS stores rows as a serialized JSON string collection.
- ✗
Use a Record Producer script to flatten the MRVS into custom table rows automatically.
Why it's wrong here
MRVS is used in catalog items, not typically record producers, and requires explicit script parsing.
- ✗
Configure a Catalog UI Policy to export MRVS rows to the sys_variable_value table.
Why it's wrong here
UI policies cannot export data to backend tables in this manner.
- ✓
Parse the JSON string using JSON.parse(current.variables.mrvs_name) in a Run Script activity and iterate through the resulting array.
Why this is correct
JSON.parse() converts the MRVS string into a workable JavaScript object array for script processing.
