Wanting to update a date field in a document library when an item with the same name is modified in a list

[ChancelorM]

Hello, I hope you all are well.

I have a document library with a date field (Date of Last Review) and another Sharepoint list with a date field(Date of Audit). The List includes "audits" that are done to review the documents from the Library. The audits results are entered to the List via a Power Apps form.  This means that there is a one to many relationship between these two, otherwise sperate sites.

What I want to do is use the date field from the List(Date of Audit) to update the date field for the entity in the Library (that shares the same name). 

I have tried a Flow using "When and item is created or Modified", but so far I cannot seem to get the output to make the update in the Library.

The field for the document name in the Library is "Title" and the field for the document name in the List is "Document Title".

Here is a look at the flow as is (does not apply the update).

This flow shows [] as the output. Any help is appreciated!

Hi @ChancelorM,

What value are you using in the Document title field of the Audits list? The name with are without the extension?

The out of the box title field in the document library contains the name of the document without the extension.

Btw, you don't have to use a Filter Array action. You can use the Filter Query field in the Get files (properties only) action as well.

Try a setup like below:

Yes, there is a difference from the Library to the List. The Library includes the file extension .docx, but the List does not include the file extension.

Here is the updates I have tried based on your recommendation. The flow states it was successful, but the field in the library did not update.

Below is what the details tab shows for the Library -

And below is what the detail look like for the List -
