Implementation of BADI FTR_CUSTOMER_EXTENT

Hi, We are implementing BADI FTR_CUSTOMER_EXTENT to enhance the transaction TS01/TS02. We have created new tab(screen) for this. But, we are unable to store data into database when the document is saved. Pl. can you let us know which method/interface we need to use to store the data into databse.

Thanks

P
