Using the coalesce function in an ArcGIS Survey123 calculation leaves empty values on feature layers if one of the fields is null when taken in the ArcGIS Survey123 web app.

解决办法

• The coalesce function works fine in the field app.
• Adding the coalesce function before each field in the calculation resolves the issue with the web app. For example, instead of using coalesce(${input1}*${input2},0), use coalesce(${input1},0)*coalesce(${input2},0).
