Report to track changes to infotypes prior to running the payroll interfac

Question

wants a report to track changes to infotypes prior to running the  payroll interface.  The attached report looks like it should work but it returns nothing.  Is there config that turns on "Track Changes": for select infotypes?  If so, can they be activated for key infotypes so this report will run?
Name, Address, position, etc.
Not attendance and absence ITs.

Hi,
IMG – Personnel Management – Personnel Admin – Tools – Revision – Set up change document:
This node has three items:
Infotypes to be logged
Field Group Definitions
Field Group Characteristics
Using these three options you define which infotypes you wish to log, then which fields, then you define which groups of fields are to be saved. Click each link, or see the sections below:
Infotypes to be logged
Here you define which PA infotype numbers you require logging. Select New Entries and enter a transaction class (A for Pers Admin, B for recruitment), then enter the infotype number and save.
Field Group Definition
When changes are made to a logged infotype, the field contents before and after are recorded. This is the very reason for logging the infotype, but there is an overhead in performance and disk space used so it needs to be given consideration. Typically you will want to record fields that are pay relevant.
Using the field group definition, you specify which fields you wish to record changes in. When any of the fields in the group are changed, all the fields in the group are saved. You can use an asterisk to log all the fields of the infotype but this is not recommended for space and performance, also there are many fields on an infotype that you will not be using, that will be saved also. Ideally you will pick individual fields of the infotype and enter them like so:
The field group number is a freely defined number you allocate to the group, it will be used in the next step. For normal use, simply pick any number not already used in that infotype. All fields with the same field group number are recorded in the log, even if they have not changed.
Click New Entries and enter the infotype number, field group number and field names that you wish to record.
Field Group Characteristics
When you have set up the field group numbers, use the field group characteristics to activate the logging of those fields. You can also specify a supplementary field group; this means that the contents of another field group can also be saved at the same time, even though the contents have not changed. In practise it is not used much. Simply select new entries, enter the transaction class, infotype, and in the DocFieldGr enter the number you assigned to the field names that you want to store, then enter L for Long Term Documents (short are not supported)
The Audit Report
To access the report showing the logged infotype changes, use the HR report tree available from various menu paths, including:
Main Menu – Human Resources – Pers Management – Administration – Info System – Reports - Documents – Infotype change – logged changes in infotype data. (RPUAUD00).
When you run the report, select the infotypes you require, and select and execute.
