Decision Limits & Constraints

This page documents the system limits and constraints for decisions in OPUS. Understanding these limits helps you design decisions that operate within platform boundaries.

Summary

Nested Decisions

Maximum Nesting Depth

Decisions can be nested up to 5 levels deep.

Depth increases by 1 for each nested decision call. Exceeding this limit will reject execution.

Example of nesting depth:

Parent Decision (depth 1)
└── Child Decision A (depth 2)
    └── Child Decision B (depth 3)
        └── Child Decision C (depth 4)
            └── Child Decision D (depth 5) ✓
                └── Child Decision E (depth 6) ✗ RejectedCopy to clipboardErrorCopied

Function Node

Execution Timeout

Each Function node has a maximum execution time of 5 seconds (5000ms).

If your function exceeds this limit, the execution will be terminated. For complex operations, consider:

• Optimising your code logic
• Breaking the operation into multiple Function nodes
