You can use error nodes in the TRANSFORM to prevent text generation under certain circumstances. If the user-defined conditions are reached, the text production is suppressed.

By using this function you can control whether the entire text can be produced, or whether it should be excluded from production and fail. One possible scenario would be for example if the data set of a product does not meet certain minimum standards, like missing product name, brand or product type.

In this given example, we want to exclude all products without a value for "category". First we create a node with the required condition. Afterwards, we create an error node and connect them both. Within the error node you can define a message that will be displayed instead of the generated text.
