Hi @gowtham1907 ,
From your description, I know that:
1. You have a form with some fields that need to be populated by users.
2. In your Dataverse, there is also a Choice field(for example, this field called “Status_choice”) and this field does not display in above form.
3. Outside the form, there are two button, one is “Draft” button, the other is “Submitted” button. When click Draft button, you want to create new record with Status_choice =Draft, when click Submitted button, you want to create a new record with Status_choice =Submitted.
If my understand is correct, you can try below formula for these two button.
Before apply below formula, make sure your Choice field has options like below:

For Draft button, set OnSelect property to(There are two fields in my form):
Patch('Expense Nature Categories',Defaults('Expense Nature Categories'),
{'Expense Nature Category (cre5c_name)':DataCardValue13.Text,
'Category ':DataCardValue16.Text,
Status_choice:Status_choice.Draft})
For Submitted button, you can try this formula:
Patch('Expense Nature Categories',Defaults('Expense Nature Categories'),
{'Expense Nature Category (cre5c_name)':DataCardValue13.Text,
'Category ':DataCardValue16.Text,
Status_choice:Status_choice.Submitted})
On your side, you should try formula like this(edit below DataverseName and ColumnName(inside your form) based on your requirement):
Patch(DataverseName,Defaults(DataverseName),{
ColumnAInForm:DataCardValue1.Text,
ColumnBInForm:DataCardValue2.Text,
...
ChoiceColumnName:ChoiceColumnName.Draft
})
Best regards,
Allen
