SAP CRM loyalty card number

Hi,

I need some information about extracting to BW loyalty card numbers and mapping between partners and cards.

I can not find card number in extractors like 0BPARTNER_ATTR, 0CRM_LOY_MA, 0CRM_LOY_MSH and so on.

Is there any extractor of cards master data (card number, status, date of validity and so on)?

Is there any extractor with mapping partners<->cards or memberships<->cards?

If no then which extractor is the best to be enhanced with these fields?

Thanks.
