Infotype 0021

Hi,

Infotype 0021 is for family/dependents right? In tcode PA30, an address can also be included for this infotype. However, the structure associated with this infotype (P0021) doesn't have the address fields. Let's say I'm using the user-exit EXIT_SAPFP50M_002 to validate the address (against a 3rd party software), is there a way for me to retrieve the address fields from infotype 0021 (given that EXIT_SAPFP50M_002 makes use of the structure PRELP)? Is there a particular structure other than P0021 that has the address fields?

Thanks! Any info on this would be great.
