Error: HTTP 400 Unrecognized field using NIM custom fields with ADDRESS USS SMREQ - OPS/MVS

Products

• OPS/MVS Event Management & Automation

Issue/Introduction

The ADDRESS USS SMREQ command fails with an "Unrecognized field" response and HTTP code 400 when including custom fields defined in the CA NIM schema.

This occurs during OPS/REXX execution when sending events to service desks like ServiceNow.

• HTTP response code: 400
• Response body starts with: Unrecognized field

The JSON trace shows custom fields (e.g., ####_app_id) are not correctly formatted as customProperties key/value pairs.

Environment

• OPS/MVS Event Management & Automation 14.0
• CA NIM (Network Integration Manager)

Cause

The ADDRESS USS SMREQ command retrieves the schema but fails to encode fields identified as "custom" into the required customProperties JSON array.

This is tracked under defect DE665510.

Resolution

Fixed in release 14.0 with PTF LU19847 and higher. 

To resolve this issue:

1. Download PTF LU19847.
2. Apply the PTF to the OPS/MVS 14.0 environment.
3. Restart the OPSUSS servers to pick up the changes.
