Extract Mobile Phone for CRM Business Partner

Hi Experts

I would like to extract the mobile phone number for a business partner from CRM. Transaction BP shows the number in the address tab, communication area together with the telephone number and the fax number.

The business content DataSource 0BP_DEF_ADDRESS_ATTR delivers only the telephone number and the fax number. Does anyone know of a DataSource that also delivers the mobile phone? Otherwise, in which table is the mobile phone number stored?

Thanks in advance

Daniel
