BDC for XK01

Hi All,

iam creating & updating Vendor master details through BDC Recording by following syntax

DATA :lt_bdcmsgcoll1 TYPE STANDARD TABLE OF bdcmsgcoll.

DATA opt TYPE ctu_params.

opt-dismode = 'N'.

opt-updmode = 'X'.

opt-cattmode ='N'.

opt-defsize = 'X'.

opt-racommit ='X'.

opt-nobinpt = 'X'.

opt-nobiend = 'X'.

CALL TRANSACTION 'XK01' USING bdcdata OPTIONS FROM opt

MESSAGES INTO lt_bdcmsgcoll1 .

i have given opt-dismode = 'N' then vendor are NOT getting created.When i give opt-dismode = 'A' or 'E' then vendors are getting created / updating .

can any one suggest me how to proceed ?

regards

Fareed
