Wizard: EDT

Wizard walkthrough · Core Studio 3.0 · Verified 2026-09-01

When to use it: you need a new extended data type — standalone, or extending a Microsoft base EDT to inherit its behavior.

Size: S · Automatable: fully.

Prerequisites

None beyond a custom model. If you’re extending, the index should be at tier ≥3 so the extends-picker lists Microsoft base EDTs.

Steps

  1. Basics — name (validated, collision-checked), model/module.
  2. Type family — String / Int / Int64 / Real / Date / UtcDateTime / Guid / Container…
  3. Family-specific properties — stringSize (default 10 for String), decimals, extends-picker from the index.
  4. Label / help / configuration key.
  5. Summary — preview, commit.

Output anatomy

  • AxEdt/<YourEdt>.xml under <root>/<Model>/<Module>/AxEdt/ — re-indexed and immediately usable as a Table wizard field type or in code.

Verify it worked

  • The EDT round-trips losslessly (including Extends and Label).
  • On-VM compile 0/0; pick it as a field type in the Table wizard on the next pass and it appears in the picker.

If it goes wrong

  • Extends-picker is empty or degraded — the index hasn’t parsed Microsoft models yet (tier <3); wait for convergence or type the base EDT name and let the build verify it exists.

Next: Table wizard (its field step can co-generate EDTs through this same builder).
