In order to be able to expand our the reserve class, it would be is necessary to create a Z implementation that will inherit from our class in order to be able the class to make the necessary expansions. This will be in the case in which the mapping of the corresponding fields does not coincide with the standard mappings we offer offered (see functional file).
1. Create Enhancement Implementation
2. Create BAdI Implementation
...
3. Create Implementation Class inheriting from our reserve class
4. we activate Activate the implementation and we already have our Z implementation of the Z to modify the mapping we wantneeded.
