In which scenario is it acceptable to assign a value directly to a component of a struct in ABAP?

Assigning a value directly to a component of a struct in ABAP is typically acceptable when you use the standard syntax of the struct followed by the component name, which is showcased in the first scenario.

In this scenario, assigning a value directly to struct-airlineid = 'LH' demonstrates the correct approach to accessing and assigning a value to a component of a struct. It adheres to proper ABAP syntax, where struct is the instance of the data structure, and airlineid is a defined component within that structure. This method promotes clarity and effectively reflects how values are maintained within the structured data type in ABAP.

Looking at the other scenarios, they either contain syntax issues or improper references to struct components, which are not considered valid in this context. This reinforces the foundation of using correct notation and understanding how to manipulate the structure properly in ABAP programming.
