Filter Array working on IDs

(1) Share

Report

Posted on by CrimellaD

Hello,

as I was rightfully suggested here, I implemented array filtering steps into my flows. I have got really good results for the most part, when managing string arrays, but I do need to compare integers (IDs).

Basically I need to get "Products" from a SP List, filter them only to contain the ones for which "Code" is listed in an Excel file (and create records for possible new entries) an this all works flawlessly.

Now, I get the updated "Products" list, filter it again on the Excel file (this I do to have all the data also from the possible new records added before). From this new Array I want to:

Filter a Mapping table (ProductID to DocumentID) and get the Products for which a relationship not yet exists: I am able to do that only by comparing strings but this allows me to create, if needed, the new relatioships in the Mapping table
Filter the Mapping table to get the Relationships records that are no longer required (products may have been removed from the Excel file) so I'd like to delete those relationships: I cannot make this part work neither filtering on numbers nor strings.

I must be making some systematic error but I really don't get it.

I could really much use even only a hint in the right direction to solve this problem.

Here an overview of a part of the flow:

Thanks

You might find this YT Tutorial helpful: Are you using the Microsoft Power Automate Filter Array Action wrong?

I cover a similar scenario in the first section of the tutorial. For more troubleshooting tips—check out this tutorial: 5 Power Automate Troubleshooting FAQs and Helpful Tips for Creating Better Flows

In this video tutorial I’ll show you 3 practical ways to use the Filter Array action and how to use it properly.

1️⃣ Cross-Referencing Data

2️⃣ Filtering by Key

3️⃣ Substring Matching

Did you know that the Condition action has a limit of 10 conditions? Although it might look like the Filter Array action can only accept one condition—this is not true. By using the advanced mode you can enter multiple conditions into a Filter Array action with an expression.

I have gone trough the proposed videos, as of right now I think I have isolated the problem as follows:

Query: and(contains(body('Join_-_Codes_String_from_Excel'),item()?['Title']),not(equals(6,item()?['ID']))) the first part correctly filters the codes based on the Title string, second part works and also removes the item with ID of 6 (this was for debugging purposes)
Query: and(contains(body('Join_-_Codes_String_from_Excel'),item()?['Title']),not(equals(body(Select_IDs_to_remove),item()?['ID']))) only the first part works, the second one doesn't apply any changes
output of Select_IDs_to_remove action has body = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10]

Any idea on why the condition is not applied when comparing it on an array?

Thank you as always
Daniele

I followed the suggested methods, and I think I have been able to isolate the problem:
Query: and(contains(body('Join_-_Codes_String_from_Excel'),item()?['Title']),not(equals(body('Select_-_Relationships'),item()?['ID']))) : only the first part of the "and" works and filters the input (which is a Get Items body output) the "not equals" does not apply any changes. The filtering array has body = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10] and I need to remove the items with that ID values from my list.
Query: and(contains(body('Join_-_Codes_String_from_Excel'),item()?['Title']),not(equals(6,item()?['ID']))) : this works and filters the List based on the Excel file data and also removes the item with ID=6
I am really not sure why this condition doesn't work when entering the array of IDs instead of the single value I have put in for debugging purposes.

Thanks for the support!

I imagine since this was posted a bit ago, you found a solution. However, I was facing this issue too and found a solution that I'll share in case others come across this post too.

For some reason the type of the array items to search and the ID weren't being read the same (either as integer or string) so I ended up wrapping the item in string when I grabbed the list of IDs into a select... and then in the filter array query, I also wrapped the item ID in string.

Example: in the Select MAP: string(item()?['ClassID']) and in the Filter Array Query: @contains(body('Select-ClassIDonly'), string(item()?['ClassID']))
