Specify hierarchy versions for timestamped data
If a data configuration supports timestamped data, you must specify a hierarchy version for each time period in the source data. A time period is a range of dates during which only one hierarchy version was used to code the source data.
For example, suppose that the source data includes the following rows:
Case ID | Start | Stop |
---|---|---|
100 |
01-01-2004 |
06-01-2004 |
200 |
06-01-2004 |
01-01-2005 |
300 |
01-01-2005 |
NA |
Additionally suppose that different versions of MedDRA were used to code the source data:
- MedDRA Version 6.1 was used until June 1, 2004.
- MedDRA Version 7.0 was used between June 1, 2004 and January 1, 2005.
- MedDRA Version 7.1 was used on January 1, 2005.
In Oracle Empirica Signal, you must specify the version of MedDRA used to code the source data for each time period as described below.
