Why trying Report using Object = T, Option = U, Qualifier = QUALIFIER, the query seems to ignore the Qualifier condition?
When generating a report, a standard screen header is used for most screens. One part of the screen header is the control center which includes the QUALIFIER parameter.
The control center determines the object type and option and the selection criteria for selecting the objects.
The control center is used with primary and line commands to control the product operation and to generate systems catalog reports. The fields in the control center portion of the screen let you identify the exact report you want.
For some reports, the Creator and Qualifier fields in the header are used only to jump to other reports.
The QUALIFIER field is inactive on reports where it is not needed. If the QUALIFIER field is inactive, its field label is simply QUALIFIER. This indicates that the field will be used when jumping to a report like the Package report where the field is active.
