Depending on the installation of the userexit at a trigger of the calling dialog object, DataView passes parameters to userexits. Parameters are always passed as character pointers. The data passed have to interpreted by the userexit itself.
The userexit parameters of DataView are divided into application parameters and standard parameters. Application parameters contain application specific data you have to define yourself. Standard parameters are automatically generated by DataView and then passed to the userexit as nominal value.
The table shows which parameters are passed to the DataView userexits installed at the triggers.
