update an entire list empty columns from another list in one pass

Posted on by

HI All,

I know how to update a column in a second list when and Item in a list is updated or added.  I am looking for a one time FLOW to update an entire list's columns from another list.

Example:

List 1 has:

Asset Tag, asset type,Serial number.

List 2 has 

Has the same 3 columns, but asset type and serial number are blank. 

I want to key on Asset Tag..

I would like to update all the blank columns in list 2 from list 1.  But I dont want to have to trigger the FLOW from an event in either list, I want to run it now for all. 

 

Is that possible?

 

TIA,

Joe

    @joef :

    I am creating a Flow now and will post when complete that will address your issue.  That said, you could accomplish your goal in just a minute by using MS Access (assuming that you are familiar with Access) - create linked tables in Access to both lists and create an update query.

    @joef 

    Here is an example that shouldmeet your needs.

    What the Flow does is:

    1. Loop through all items in list 2
    2. Find the matching entry in List1
    3. Updates List 2 based on the values in the matching List1 entry

    Please note the OData filter when I am finding the entries in List1.  When using OData filters you need to use a columns internal name - that's why I have Asset-x0020_Tag instead of Asset Tag.  To see the internal name, go into list settings and click on the column name - the internal name will be at the end of the URL after "Field=".  Also note the single quotes around the parameter.

    Thanks @ScottShearer ,

    I dont see how I am updating list 2 from list 1...

     

    When I try to add the dynamic cointent, I only see what I am pulling from list 2 in the first step.

    Where do i find list 1's content?  

     

    Thanks again,

    Joe

    Hi Scott,

    Access just seemed to be much more straight forward than trying to figure out FLOW for this.

     

    Thanks for you help!!!
