Salesforce Picklist fields have a limitation when reporting, as different arrangements of selections count as separate values, when trying to group reports.
i.e If you have Value A and B, and your selections are;
2. A AND B
When you run a grouping reporting within Salesforce, it will say frequency of A=1.
Multi-Select Picklist Frequency Reports is a 3rd Party app that can be installed and used within Salesforce which will see a frequency of A=2.
1. After installation of the App, in the top-right corner select Multipicklist Frequency on the dropdown menu.
2. Follow the instructions on the screen to create your own Multipicklist Frequency Report. Click Run.
3. You will receive a pop-up message to say you have been successful and will receive an email after a few minutes.
4. This is what your report will look like in the email.
If you need further assistance using Multipicklist please email the Marzapps Support team who will respond within two business days.
