How to subtract a number of days from a date field

Hi,

This is for BI Publisher (JDE) in a Microsoft Word template.

I need to get the previous date by subtracting 32 days from the date.

Example: I need to subtract 32 days from 2019-04-30 and return 2019-03-29.

Date Field: <ReadDate_ID4>2019-04-30</ReadDate_ID4>

Days Field: <Days_ID33>32</Days_ID33>

Does anyone know how to do this?

Thanks,

Tony
