Hi Experts,
I am currently working on a requirement in the ServiceNow Mobile App (IT Asset Management Mobile scope / Now Agent Mobile App) and would appreciate guidance on the recommended implementation approach and best practices.
Business Requirement
We have created an Input Form Screen in Mobile App Builder that allows technicians to scan and update asset information during physical asset verification activities.
Barcode Fields on Mobile Screen
- Asset Tag
- Serial Number
- RFID Tag
- Cubicle ID
Expected Process Flow
Step 1 – Scan Asset Tag
The technician scans the Asset Tag barcode.
The scanned Asset Tag should be used to identify an existing asset record in the alm_hardware table.
Step 2 – Scan Additional Values
After the asset is identified, the technician scans:
- Serial Number
- RFID Tag
- Cubicle ID(custom field created in alm_hardware table)
Step 3 – Update Existing Asset Record
The scanned values should update the corresponding asset record.
Field mapping requirements:
Scanned Value | Asset Field |
Asset Tag | Used to identify the record |
Serial Number | Serial Number field on Asset record |
RFID Tag | RFID Tag field |
Cubicle ID | Custom Cubicle ID field (new field to be created on Asset table) |
Query/Questions?
- Recommended Approach for Updating Existing Asset Records?
Once the asset is identified using the scanned Asset Tag, what is the recommended approach to update the existing alm_hardware record from a Mobile App Builder Input Form Screen?
I'm looking for a scalable and maintainable solution that follows ServiceNow mobile development best practices.
- Barcode Input Validation?
We also need validation of the scanned barcode values before updating the asset record.
RFID Tag Validation
Cubicle ID Validation
- Where Should Validation Be Implemented?
What is the recommended location for enforcing validation in Mobile App Builder?
Ideally, we'd like users to receive validation feedback immediately on the mobile app while also ensuring server-side enforcement.
Additional Considerations
- Has anyone implemented a similar asset verification or asset inventory scanning use case in Now Agent app?
- Are there any OOB patterns or reusable components available for barcode-driven asset updates?
- Any performance considerations when querying assets by Asset Tag from a mobile workflow?
Any implementation examples, architecture recommendations, screenshots, or best-practice patterns would be greatly appreciated.
Thanks in advance for your guidance and suggestions.
