  How to use it: 
  To use the read-by-association operation, developers must first define the association between two entities in the ABAP programming model. This is done by creating an association object in the ABAP programming model. Once the association is defined, developers can use the read-by-association operation to read data from both entities in a single request.

This will ensure that the data is retrieved correctly and efficiently.
