Infopath Issues

[Gunasekaran Sambandhan]

Hi friends,
Please help me, I strugling with the following problem.

I was created webservice

My infopath form fields are taken from the webservice Recieve and submit
data
and in the data source every fields are displayed.
Using that fields i just drag and drop the fields to the form.

every thing is fine, My problem is some of the fields are displayed with
Manadatory(can't be blank). I can't able to remove that option because it is
disabled.

How could i remove that option, is there any problem in webservice

I don't know much about webservice, but by chance, are all the required
fields date pickers? I have found that datepicker fields sometimes default to
required.
