Merge duplicates should require sex AND date of birth to be equal [1]

[MartinWahnschaffe]

Feature Description

Duplicate detection for retrospective merging considers some properties of the cases. Among others the sex and date of birth.

Problem Description

Currently the case is considered possible duplicate when sex OR date of birth are available and equal.

Proposed Change

Instead the logic should be an AND.
So when two cases of the same sex have a different date of birth, they should not be considered possible duplicates.

Additional info

Consider "unknown" / should not conflict with male or sth. else

• two cases of the same sex but different date of birth should not be considered possible duplicates.
• for two cases with missing data (NA) for one of the variables like sex for one of the cases, then this variable should not be considered in duplicate detection.
