Phone number information is stored in the F0115 table.
Phone types are listed in the 01/PH UDC. It is common for the JD Edwards phone type to be blank. To find phones where the phone type is blank, use the <BLANK> token. If no value is specified for the phone type setting, the first entry by line number (RCK7 field) will be returned.
Who's who line ID comes from the IDLN field in the F0115 Address Book - Phone Numbers table.
Related person ID comes from the CNLN field in the F0115 Address Book - Phone Numbers table. 'Related Person ID' only works for E1. For World users, this field will be ignored.
Related persons of an Address Book entry are defined in the F01112 Related Person table. A common example of this is a dependent of an employee.
