I'm sure most of you are familiar with utility %SYS.MONLBL that is crucial when analysing code performance bottlenecks. It allows you to select a number of routines that you want to monitor at runtime and also specify what process(es) you want to watch. BUT, what if you do not know exactly, what process would execute your code? This is true with many web based (CSP/REST) applications today. You want to minimize the resource utilization on your production system that needs analysis. So, how about doing a small tweak?

1. Define an INC file with these macros:

REST API Issue

I have a rest API Class used for getting data from Cache 2018 version.

Introducing Smart Clinical Sidechick — the intelligent, no-drama partner your EHR wishes it could be. She reads FHIR data in real time, interprets lab results without ghosting, and explains clinical alerts like she actually cares. Built with GPT-4 brains and YAML sass, she’s not here to replace your main EHR—just to make it look bad. Tired of irrelevant alerts and cryptic warnings? Sidechick serves up real, explainable insights, not vague “elevated risk” vibes. And when your backend crashes, she doesn’t panic—she self-heals.

I'm creating a Business Process that:

  1. Transforms one object into another using DTL
  2. Sends this object to an operation
  3. Transform the object obtained in first point into another one using DTL
  4. Sends the second object to an operation

The Business Process is created with BPL, and objects are stored in BP context. When I execute this Process, in the 3rd point the object obtained in first transformation doesn't exist. It's empty.

I have tried to make transformation before making CALL's, I mean:

For background, I've developed code that relies on %JSON.Adaptor functionality across an entire package of classes in our codebase. In regenerating these classes with %JSON.Adaptor as a superclass, I've encountered compilation errors from the JSON adaptor generators in certain classes, triggered by certain property types or parameters that are incompatible.
