Restrict authorizations for loads from HR to BW for certain data

Question

Hi,
our customer wants protect some data in the HR productive system. This data are defined/restricted by certain personal areas.
It is not enough to use reporting authorizations in BW to restrict presentation in queries or use filters in infopackets during load to avoid this data.
The requirement is to make load of such data from HR to BW absolutely impossible, even BW administrator cannot see them and must not be able to load them.
We will probably have to somehow limit ALEREMOTE users authorizations in BW. I do not know how and I even doubt, that extractors in HR source system perform authorizations checks for fields.
Is there any way to do this?
Thank you very much,
Petr

Hi Petr,
Create a general enhancement program (restricted authorization) with generic name, which should be called dynamically for every datasource.

Not personally tested but check following.
In that program, you may try applying following logic:
1) You may need to use TYPE ANY field symbols
2) In While Loop until all fields of C_T_DATA checked, may be a counter based on total number of fields.
    DELETE C_T_DATA where <TYPE_ANY1> EQ (OR use IN) specific value(s) of Personnel Area
    DELETE C_T_DATA where <TYPE_ANY1> CS (Contains, check pattern) specific value(s) of Personnel Area
ENDWHILE.
Optionally: For Standard Daatsources in the same program you can add logic based on standard field only "WERKS".
Note: You may need to research on dynamic pointing using field symbols for every field.
