I was working on a project requiring the creation of many SUPPQUAL data which are supplemental qualifiers data domains within the CDISC data model. The majority of this effort is to identify the SUPPQUAL variables and its related identification variables. You would then need to transpose the source data into the vertical structure for this special purpose domain data structure as specified in SDTM. This does not require a rocket scientist, so I have created an interface on the iPhone where you can create this SUPPQUAL data and then get a preview of the resulting dataset.
The video I have recorded below will illustrate how this can be done with relatively little effort.
