Surviving Microsoft Dynamics Business Central Breaking Changes using AL Preprocessor Directives

Question

Supporting multiple Business Central versions is getting more challenging, especially now that BC27 confirms several silent changes from 26.x as official breaking changes. Instead of splitting your app or maintaining separate branches, preprocessor directives give you a clean, repeatable way to handle version differences.

This no BS guide I wrote covers:

• How directives work in AL
• How Microsoft uses versioned symbols
• Real code from the NoSeriesManagement and Invoice Posting Buffer transitions
• A simple pattern for long-term maintenance
