Solution Verified - Updated -

Issue

  • A spreadsheet based Decision Table has been uploaded in a package of Business Central where the rules defined inside it uses an external function defined in a DRL on the same package. In such a scenario users can successfully Build & Deploy on the project containing those Decision Table and DRL in Business Central but while clicking on Validate button after opening the Decision Table, it fails because it cannot find functions. The following exception gets logged.
