Which statement about OutSystems blocks is NOT correct?

The statement that a block can only be reused once is not correct. In OutSystems, a block is designed specifically for reuse across different parts of an application or even across different applications. This means that once a block is created, it can be reused multiple times within the same application or across various applications, providing a significant advantage in terms of efficiency and consistency in development.

This capability allows developers to streamline the development process by designing a block once and incorporating it wherever needed, ensuring uniformity in functionality and design. Such reuse not only minimizes duplication of effort but also facilitates easier maintenance. If any changes are made to the block, those changes will reflect across all instances where the block is used, enhancing maintainability and ensuring that updates are uniformly applied.

The other statements highlight the purpose and advantages of using blocks in OutSystems. Blocks indeed promote reuse, encapsulate their own logic, and improve maintenance, making them essential components of the development framework.
