Accessing combination of keys as an alternate key to avoid duplicate record creation

(0) ShareShare

Posted on by CRM Beginner 795

Hi All,

I am creating a record using my own C# code. I have used emailaddress(text field) as an altenate key.But now, i want one more field to act as an alternate key(lookup field) But lookup fields can't be alternate keys.So, ow can i use the combination of both fields as an alternate key so that if same email addresses allows us to create a record only and only if the other field value is different.

Thanks for any help!

    Hi,

    As dynamics CRM  does not support alternate keys for lookup. So in that case I would recommend create another single line text and make it as alternate key. When you create record at that time onchagne of lookup you will need to set lookup value/text in this  new single line text . If its found any duplicate it will give  error message .Hope this helps.

    Hi,

    You need to set the value in on change event. How you are getting value please share your code.

    Hi,

    is ther a bug I don't see the different responses?

    What I would is to concatenate the email address and the string of the lookup.

    You should probably do it on a post event(create/update) and then update the record with the concatenated string/unique key
