Our organization works from Grant funds and we can not co-mingle grants funds. Therefore I need to figure out how to set up employees in PR to be able to track each grant.

Example of what I'm looking at: Staff 1 works 26 hours a month on our CSRAE grant and she will be working 8.5 hours a month on the new DOJ grant, and Staff 2 will be working on both grants as well. So I will be processing 2 payrolls at the end of the month for them. How do I set this up in PR to be able to track and record the separate PR and the PR taxes?
And how can I run my month end reports showing each grant program expenses ?
