Nested Snippets (snippets within snippets)

Nested snippets allow you to use a snippet inside another snippet in Strategy Designer, including recursively (a snippet calling itself) or mutually (snippet A calling B and B calling A). This significantly increases reusability, but also introduces new considerations for activation, versioning, and debugging.

Target Audience

  • Business analysts and pricing managers designing strategies in Strategy Designer.

  • Solution consultants and implementers configuring reusable logic.

  • Administrators who need to understand activation and versioning impacts of nested snippets.

Prerequisites

Before working with snippets within snippets, ensure that:

  • Strategy Designer is available and configured in your partition.

  • Snippets are already enabled and you are familiar with basic snippet concepts (creating, using in strategies, versioning).

  • You understand the Activation and Versioning rules for strategies, snippets and lookups.

What is a Nested Snippet?

A nested snippet is a snippet that uses another snippet as a block in its own workspace (child snippet inside a parent snippet). Strategy Designer supports:

  • Using a snippet inside any other snippet.

  • Using the same snippet inside itself (self-recursion).

  • Mutual references where snippet A calls B and B calls A.

Typical Use Cases

Nested snippets are especially useful when:

  • You want a driving snippet to orchestrate multiple smaller snippets (e.g., several markdown or pricing factor snippets) and choose which ones to apply.

  • Common logic (e.g., rounding, eligibility checks, normalization) should be shared between multiple higher-level snippets.

  • You want to layer abstraction: low-level data access/lookups, mid-level calculations, and high-level orchestration, each as separate snippets.

Creating a Simple Nested Snippet

This section walks through a simple case where Snippet A calls Snippet B.

Step 1 – Create or Identify the Child Snippet

  1. Go to the Snippets tab.

  2. Either:

    • Create a new snippet using Add > New Snippet, or

    • Open an existing snippet that you want to reuse as a child.

  3. Design the snippet as usual:

    • Define arguments (names, types, defaults) as needed.

    • Build the logic inside the snippet body.

    • Connect its output to the Return field.

This snippet will become the child snippet (Snippet B).

Step 2 – Create the Parent Snippet

  1. Still on the Snippets tab, use Add > New Snippet to create another snippet (Snippet A).

  2. Define its arguments and return type (via the block connected to Return) according to what the higher-level logic should expose.

Step 3 – Insert the Child Snippet into the Parent

  1. With Snippet A open:

    • Locate Snippet B in the Toolbox under Snippets.

    • Drag the Snippet B block into Snippet A’s workspace.

  2. Wire Snippet B’s inputs:

    • Provide values directly.

    • Or forward values from Snippet A’s arguments (e.g., pass-through or transformed values).

  3. Use Snippet B’s output:

    • Connect its output into Snippet A’s logic (e.g., arithmetic operations, conditions).

    • Optionally, connect it directly to Snippet A’s Return to simple wrap B.

At this point, you have created a nested snippet: Snippet A depends on Snippet B.
