Hi guys,

I'm stuck with this challenge and do not find out how to pass it.

I have this error when I try to pass this challenge :


My report is configured as follow :


And the dashboard :


The roll up summary on account is configured like this :


I do not achieve to create a tabular chart in the lightning dahsboard.
I tried many things with the source report but I did not succeeded.

Is there something I should do differently ?

Regards

I need some help and I am only asking this because I am new to APEX Triggers:

On the opportunity line item, we have a Picklist.  When this picklist value is changed to "Won"

My organization has a process which does the following:

1) On the opportunity line item the value is changed to "Won"

2) A Work flow kicks off that sends an outbound message to our local server

3) This process creates a design win on a custom object called Design_Win__c based off of the opportunity line item that had the value changed.  It creates a 1 to 1 relationship with the Opportunity Line Item to Design Win


One process that we allow (currently disabled, but cannot be) is the changing of a part number on that same opportunity line item (this is done by a custom s-control).  When the part number is changed, it deletes and creates a new opportunity line item.  This assigns a new Id to the line item.

We store the original line item Id on the Design Win that was created, but when the original line item deleted, it breaks the 1 to 1 relationship

What I need to accomplish and need help with, is to write a trigger (if this is possible):

1) when the part is changed, and deletes, on the opportunity line item

2) it would query the design win object using the opp line item Id that we have stored on the Design Win.

3) if there is a record found that matches the query, then delete the record

Can someone please help me here, I have no idea how to write a trigger to do this

Thanks is advance
