How to update an existing item in SP List from another SP List ?

(0) ShareShare
ReportReport
Posted on by 86

Hello,

 

I have two SP List with the same structure and I want to update both of my SP List when an item is modified in SP List 1 or in SP List 2.

But I don't have any column ID in this SP List, because my data is identified by 3 criteria : Structure, City and Date.

 

So, how can I do to specify that my "ID = Structure + City + Date" ?

 

Thank you for your help 🙂

    Hello @nliu 

    You should use the ID value of the "Get Items" action, and not the ID of the output of the trigger.

    Could you check that?

    Hope it helps.

    Hi @nliu 

    Try to use the internal name of the column in the filters. Though you renamed the column, only the display name will get changed and not the internal name. Navigate to the List settings page and click on the column, you can see the internal name on the end of the URL in the address bar.

     

    Hope it helps, please like it or mark it as a solution if it resolves ur clarification or issue

    @fchopo 

    Hey I tried to rename my columns like this "Structure", "Ville" and "Date" but it says that the column "Structure" doesn't exist. That it might be deleted by an other user  :

     

    {
    "status": 400,
    "message": "La colonne « Structure Â» n’existe pas. Elle a peut-être été supprimée par un autre utilisateur.\r\nclientRequestId: 53a3027b-e50e-48f7-842b-9bea0f9baa10\r\nserviceRequestId: 53a3027b-e50e-48f7-842b-9bea0f9baa10"
    }

    @nliu It doesn't work because of the ' character in the expression (structuredel'enduitsuperficiel)

    Can you try to rename your columns, not using special characters like ´ ` ' ?

    Hi @nliu 

    In your filters you had included the column name with '/' and I don't think so SharePoint will have an internal name with '/'. You told that updating one list should update the other. How would you know which list item is updated, so I asked you to check the list name and update the other list.

    Hello @nliu 

    Please, remove the white spaces in the name of the columns when writing the filter expression, and use quote to surround values. Have a look at this example: PériodedeRéalisation eq '2020-03-05'

    Hope it helps!
