Hi Meenal,
This is FDA business rule (FDAB009):
All paired variables should have a one-to-one relationship. Examples include short name and name of test; parameter name and parameter code or number; variable name and variable label, etc.
'All values of Qualifier Variable Label (QLABEL) should be the same for a given value of Qualifier Variable Name (QNAM).
Some users (e.g., FDA Medical Reviewers) prefer to work using variable Labels instead of Names. The same Labels for different variables are confusing.
Common implementation is to use Labels like "Reported Term for the Medical History 1", "Reported Term for the Medical History 2", etc.
Kind Regards,

Without trying to give a judgement, this is interesting ...
I always believed the first thing reviewers do in their systems when importing the XPT datasets is to:
- recombine character strings >200 characters from "parent" dataset and "SUPPQUAL" dataset into a single string (using the label of the parent variable)
- after this, move all remaining "SUPPQUAL" variables by QNAM back to the parent dataset, i.e. each QNAM value becomes a column in the original dataset.
This is functionality that simple (review) tools like the "Smart Submission Dataset Viewer" master. Also SAS- or R-based software can easily do this.
Also, what would be the procedure if the original label is already 39 or 40 characters long? Adding a blank plus a sequence number would then violate the 40 character limitation.
Hi Siergy,
I was wondering whether this rule FDAB009 checks across the domains or within the domain .
Please clarify.
Thanks in Advance.

Hi Sri,
Now this rule works only within each domain.
Kind Regards,

Based on section 4.1.5.3.2 of SDTM Ig, if the variable value is greater than 200 characters, we place the first 200 characters in standard domain and rest in supplemental qualifier domain. The QNAM will have prefix 1,2 ... but the QLABEL stays the same. The example given also has QLABEL same for MHTERM1 and MHTERM2. However the Pinnacle gives the warning "Inconsistent value for QNAM within QLABEL"
