Enhancement: QC of Dataset before NCA to prevent app crashing

[js3110]

Description

During the mapping a check on no duplicates should be done by all concentration groupping variables and time c(STUDYID, ANALYTE, USUBJID, DOSNO, other_conc_group_varaibles, TIME). If there are duplicates, a notification error should be raised to the user specifying at least one of the duplicates found and that the mapping cannot proceed until they solve that.

Definition of Done

The requirements for the feature to be complete:

• If duplicated data present, notify and show which rows are duplicated
• Do not allow the mapping or subsequent analysis of the data, preventing the app crashing
