Hi @AkshayAuradkar,
Do you want to update data without using form?
Actually, whether you use form to update has no difference on updating sharepoint list.
The difference is only about the formula that you use to update.
If you use form, you should use SubmitForm() function. If you not use form, you should use patch() function or collect() function to update.
Could you tell me
1)the controls that you use to update? a datepicker and a drop down?
2)formula in the drop down's Items?
3)fields data type in your sharepoint list?
I assume that:
you use a datepicker and a drop down to update and datepicker is used to update a date type field, drop down is used to update a text type field.
If so, you should use formula like this to update:
Patch(sca,Defaults(sca),{fieldname1:datapicker1.SelectedDate,fieldname2:dropdown1.Selected.fieldname})
//fieldname1,fieldname2 are the fields in your list
fieldname is the field in the drop down's Items
Best regards,
