BackToRS Posted August 4, 2023 Share Posted August 4, 2023 (edited) Erm, solved. RequestInputDto, RequestService, RequestController for retrieve the data. PriceIndicationOutputDto, PriceIndicationService, PriceIndicationController for returning and calculating the retrieved data. Spoiler Hello, I'm having some structure issue which exceeds my logic Maybe it's easy to solve for somebody more experienced: Breakdown https://imgur.com/a/bl4ngp4. <<<. See the //TODO comments RequestInputDto consists of 3 client input fields PriceIndication consists of about 12 variables. These variables need the RequestInputDto's data for all of them to be calculated. After that, the PriceIndication output must be returned to json Im a little lost on where to catch what and calculate who.. something like that Please reply question if you need more info Or reply clarification maybe Thanks in advance, BackToRS Edited August 5, 2023 by BackToRS Quote Link to comment Share on other sites More sharing options...
