Update date on list if matching filename found in library

hi there,

I was wondering if you guys can help me figure it out. I am stuck.

I'm trying to create a flow that will do the following:

When a file is created or modified in a document library, insert a date in a list column.

So say I have a LIST called TestList and it has the following columns:

First Name, Last Name, Gender, Date, UniqueID (which is a calculated field that concatenates the first 3 columns)

First Name	Last Name	Choice	Filedate	UniqueID
John	Smith	R1A		John_Smith_R1A
Jane	Doe	V2A		Jane_Doe_V2A

And then I have a DOCUMENT LIBRARY called TestLib which is where pdf files that are named exactly like the UniqueId on the list are saved (no metadata, just filenames). So the library will contain:

John_Smith_R1A.pdf

Jane_Doe_V2A.pdf

I need it so that every time a matching filename is placed in the library, the flow will run and put a date on the "FileDate" field of the matching list item.

Date is ideally the modified date. Also, only update ones with no dates so if a date exists then don't update it.

I tried to create this flow:

But in "Get Item" I can't get the "UniqueID" field. It is only showing me "ID" to pick from.

Can someone please help?

Thank you so much in advance,

Hi!

I would try to add a 'get items' instead, and filter those whose UniqueID matches your current file name without extension.

You can filter by means of an ODATA expression inside 'Get items' or by a 'Filter array' action block.

Let's assume you implement it by means of an ODATA expression, so it will be easier:

So your 'Get items' output will be an array, ideally you will get either 0 or 1 elements inside. You can evaluate its length by means of one or more Condition action blocks and act accordingly, the trick is to evaluate 'Get items' outputs length by means of the following WDL expression:

length(body('Get_items')?['value'])

If you are unfamiliar with ODATA expressions, please check this great article:

Hope this helps
