HR tables nightmare

Question

Hi Friends/Experts,
This is really a silly question from  my "Global security implementation Project"
An issue came up:
How do we access the infotypes in a role , list the infotypes with description for that role
Now this is what I did
1. SE16 - AGR-1251  gives the ouput , filtered  by keyword infty and infoty got the list
2. pulled all the infotyes being used in the HR system with its description
3. wrote a lookup to get the infotype and its description specific to that role
Now the fun part is :
the AGR-1251 does not expand the ranges for infotypes having from(LOW) and to(HIGH) value
so i missed out on many infotypes in range, manual entry is not an acceptable path or solution.
Simple question with no answer available so far is
how do you expand the From and to value to get all the infotypes in range  in the role?
example below(part of AGR_1251)  the low and high column is what I am talking about
FIELD     LOW     HIGH     MODIFIED     DELETED     COPIED     NEU     NODE
INFTY     105          G               O     47
INFTY     167     171     G               O     47
INFTY     194     195     G               O     47
INFTY     207     210     G               O     47
INFTY     377     378     G               O     47
My input is what you entered in role is what you get, anyone with a different approach or idea

Answer 1

The best people to analyse HR authorizations in my opinion are those who understand the data and config. There are a lot of options... so try to work closely together with them otherwise it will be futile.
A little example is P_PERNR. Finding an infotype or range of this can go in all directions and overrides other authorizations. Avoiding ranges is generally good advise anywhere in SAP security....
The executive summary in this case is in the function module HR_READ_INFOTYPE's code if you want to read it...
