Updating a secondary list with the values from a primary list

(0) ShareShare
ReportReport
Posted on by 509

I've got List A and List B. 

 

When an item is List A I want Flow to copy the item to List B. I'm adding some additional fields which will be mandatory for the next stage.

 

I'm using a Get Items action to get the values from List A, then I have an Apply to each loop with value as the output. This is followed by a Update item action which I'm pointing at List B and using the values returned from the Get Items action to update the fields. 

 

This is part of a larger flow (should I create it as it's own separate Flow?). I'm checking the results from  the Update item action and it seems to be showing the item values in the Id and Body fields but on the output I'm getting a 404. I've haven't recreated all the fields from List A to list B yet as I wanted to run a proof of concept test.

 

Any ideas where I'm going wrong?

    Hi @darrenfloyd666 

     

    Most likely your List B identifier is wrong hence you getting 404 record not found. The unique identifiers are system generated when you create a record in SharePoint. So to get the List B identifier you need to use List items filter query using List A values. I hope there are some unique column values in each records in List B. Say for example Name or Title is unique then you could use the filter as name to find the id of each list record from B.

     

    If you need any further help in this please let me know.

     

    Thanks
