...
Create implementation of BAdI:

Moreover, a PBO module needs to be added in the PBO logic:
This logic, retrieve the data of these fields in case the invoice had been saved in data base before, using the save button in the posting screen(
)

...
Enhance BAdI /EDGE/BADI_EI_IT_SAVE_BUTTON

...
In these methods we need to enhance the changing parameter CS_STRUCTURE_GEN adding the new fields data to it, to be able to save it in data base and retrieve further on:
