Patch Function PowerApps

[sumitmukund]

Hi All,

We have below queries regarding the Patch function.

1. Does Patch requires the data source to be refreshed before we perform the Patch operation?

2. Will Patch function refresh the DataSource and we can see updated values back immediately or we need to perform refresh after the patch.?

3. How to know if the Patch was successful?

4. When doing an insert with Patch does it first inserts a blank row and then updates the values back into the row?

We are concerned with the above queries as we have observed inconsistent behaviour with the Patch Function.

Much appreciated for any help!

Thanks

Hi @sumitmukund ,

Your questions

1. Does Patch requires the data source to be refreshed before we perform the Patch operation?

No

2. Will Patch function refresh the DataSource and we can see updated values back immediately or we need to perform refresh after the patch.?
No and Yes(Refresh needed)

3. How to know if the Patch was successful?

Refresh and do a lookup is probably the best, but you may get better answers

4. When doing an insert with Patch does it first inserts a blank row and then updates the values back into the row?
I do not believe so

The main thing I wanted to tell you here is that there are some bugs, one in particular is writing to existing records where the target value is blank. I always use UpdateIf for existing records and have found it very reliable. You can also update multiple matching records without needing a ForAll loop.

Hi @WarrenBelz 

Firstly thank you so much for an insightful response. We are trying to evaluate the performance and reliability of the UpdateIf function as suggested.

Thanks
