No come on..

You cannot expect that that sentence all by itself is going to get you a good answer... its gotta be a trick.

That being said, there are several ways this can happen

1. You are using a LookUp to Match the Patch and it comes back null

2. You are using an UpdateIf and you are patching multiple records accidentally and should be using a LookUp

3. you are using a Patch and your Filter is just bad
4. you have a bad forall

Thats the only ways I know of to make that happen

how about sharing more details.. or at least marking this as the answer because it is ;-)

Check the relationship of your database tables. You are updating many side tables.

Can you share more information how you are updating/patching the rows? Is it using table field GUID or some other field?

Ensure that when you’re updating a row in Dataverse, you are using a unique identifier (such as the row’s GUID or Primary Key) to target the specific row. Without this, Power Apps may not know which row to update and could accidentally update multiple rows.

Example with Patch function:

Patch( YourTable, LookUp(YourTable, YourPrimaryKeyField = SelectedRow.PrimaryKeyField), { FieldToUpdate: NewValue } )
