What It Is

GDT Where Used PLUS is a code analysis and archiving tool from crocodilebytes.com, positioned for maintaining customized Microsoft Dynamics NAV projects. It mainly addresses the difficulty of tracing source code after years of customization, assessing the impact before upgrading to a newer version, and helping project managers review development progress and code changes.

Core Capabilities

The tool can analyze NAV objects, functions, and fields, and provides a “where used” view for reference relationships. It supports NAV 5, NAV2009, NAV2013, NAV2015, NAV2016, NAV2017, NAV2018, and Business Central version 14. Source code can be imported directly via finsql, or from txt files. It also supports multi-project and multi-version management, with timestamped versions and automatic comparison between different source versions. CodeGuard can monitor whether modifications are retained and scan code comments inside objects; the code viewer provides syntax highlighting and function links. For comparison, it integrates with Beyond Compare and WinMerge, and project data can be placed in a network directory for team sharing.

Pricing

The page indicates that a test license can be requested. The full version is priced at around 256.90 Euro/year or 256.90 US$/year and includes 1 project; additional projects cost 125.00$. The payment process includes registration, email confirmation, a Paypal payment request or bank transfer, and license activation after payment.

Pros and Cons

Its strengths are its very clear positioning: for legacy NAV customization projects, reference analysis, version archiving, and upgrade impact investigation can be highly valuable. Combined with Beyond Compare/WinMerge, it can also reduce the manual effort required for code comparison. The downsides are also obvious: support appears limited to NAV and BC 14, with no visible support for newer Business Central AL or cloud development. The program requires a permanent internet connection for license validation, and when creating projects or importing versions, it also synchronizes descriptions and version dates to the server, making it unsuitable for fully offline or highly regulated internal network environments. The website documentation contains spelling mistakes and leftover template text, which does not inspire much confidence in its credibility or maintainability.

Who It’s For

It is suitable for developers, implementation consultants, and project managers who are still maintaining legacy Dynamics NAV projects, especially teams that need pre-upgrade code inventory, reference tracking, change auditing, and greater transparency into project progress.
