Issue with Adhoc queries

Hi,

Background: 3 additional fields were added to infotype 0023 to capture the position at the previous organization, Years of exp and Months of previous exp.

The year and Month of previous exp gets populated automatically if you save the start date and end date.

Issue: We try to populate a repot using adhoc query but it doesnot give proper data. example if 0023 has been updated for 100 employees the output would reflect only for 20 odd numbers.

There is no authorization problem

Can anyone suggest why we are facing this issue and if this can be resolved also is there any standard SAP reprot which can give a listing of 0023 for a list of employees
