Unparameterisable parameters
Every now and then you get a client who asks a programmer to create a write-protected parameter on the program selection screen. It’s a bit dumb given that the whole idea of parameters is that they are parameterisable. But there you go, it takes all sorts. Clients have so much imagination that SAP should create a cinema module, SAP CI, especially so they can screen all the films they carry around in their heads.
