Getting Number field with decimal in Datasource...

Hi,

I am loading a flatfile into the data source and there I make one fld Contact No. as NUMC and whenever I am loading it and check into the Preview tab this filed is coming with decimal point like Master file has 123456 but the preview is showing 123.456. Even when I tried to load this field as blank then that fld instead to blank coming with value as 0. So need suport.

Regards,

Ashish D.
