Known Bugs

This page lists known bugs in BenMAP along with suggested workarounds.

Known Bugs:

Overcounting with Multiple HIFs

Description: When multiple Health Impact Function (HIF) groups which share a HIF are selected, BenMAP may errantly count that endpoint multiple times. For example, if the user selects both the Mortality – Primary and Mortality – All groups, the incidence and valuation for the shared HIFs such as the non-race or ethnicity-stratified functions may be doubled.

Workaround: To run multiple HIF groups which share a HIF, run each group as a separate BenMAP run. Then download results and combine results as desired.

Version identified: UI v0.4, API v0.4, DB v18
