I want to make the fields as required entry for a certaib transactions and I also want to block/make other fields invisible because we will not input any values on it. I try to go to SHD0. When i try to create some other fields are not there for example in F-58/FBZ4. I can find the field inside the processing. And where I can make fields as require entry in order not to allow users to process incomplete information. Please help GURUS
