problem in BDC

Hi All,

I have a BDC prog in which i am recording transaction MB1C

PERFORM fill_bdc_data USING:

c_check 'SAPMM07M' '0421',

space 'BDC_OKCODE' '=NLE',

space 'MSEG-MATNR(01)' <fs_stock_data>-matnr,

space 'MSEG-ERFMG(01)' w_erfmg,

space 'MSEG-ERFME(01)' <fs_stock_data>-erfme,

space 'MSEG-LGORT(01)' <fs_stock_data>-lgort,

space 'MSEG-CHARG(01)' <fs_stock_data>-charg,

c_check 'SAPMM07M' '410',

space 'BDC_OKCODE' '=ENTE',

space 'DM07M-HSDAT_INPUT' <fs_stock_data>-hsdat_input.

endform.

I have used like above.

in debugging mode i cud see the values in BDCDATA structure but only one field production date(HSDAT_INPUT) value is not passing to screen,this is a mandatory field it is asking for that field.

What could be the problem??

Regards,
