Solution 1:
You can report on contact details using the 'Person Contact (Personnel)' table. Here you can filter by person reference number or by Contact Type, for example.
Contact Type Key:
HEM = Personal Email Address
EMAIL = Work Email Address
MOB = Personal Mobile Number
HTN = Home Telephone Number
You may be limited on what data you can pull in conjunction with contact details on this report. Meaning, if you try to add in a column that does not overlap the Person Contact table, the report will return as blank. Just delete the additional column(s) to revert.
Solution 2:
Instead of adding in a new 'Column' for email addresses, add the following 'Calculation' and the email addresses should pull successfully:
PRBI_GET_CONTACT_TEXT(P_EMPNO=>PRCI_HR_PERSON_MASTER.PERSON_REFERENCE, P_CONTACT_TYPE=>'EMAIL')
