Customer Master not updated when creating BP- BAPIBUSISM007_CREATEFROMDATA

Hi All

When I creating BP with TCODE BP-with BP role ISM020 , BP is created and all the tables are updated.

But when I create BP programmatically with the BAPI -BAPIBUSISM007_CREATEFROMDATA

Though the BP is created ,But The customer master tables are not updated(KNVV,KNB1,KNA1)

Only table jjtvm is updated.

Hence when we create SALES order , the msg appers that the  'ROLE MEDIA CUSTOMER DOES NOT EXIST FOR BP(BPNO)

Need some help.

regards
