AX – D365FO – Write a recursive method in X++

This post describes how to write a recursive method in X++

In this example I get all the child Categories of a given Parent Category and write them into an info log.

    private void getCategoriesRecursive(Category _parentCategory)
    {
        EcoResCategory  ecoResCategory;
        while select ecoResCategory
            where ecoResCategory.parentCategory == _parentCategory
        {
            info(ecoResCategory.Name);
            this.getCategoriesRecursive(ecoResCategory.RecId);
        }
    }
