I followed the instructions exactly in the force.com workbook section for "Secure Your System", but for some reason it won't allow my sales person permission set to create any line item records...The only way I can fix that is giving him the same object permissions on Merchandise Object, but that's not how the instructions told me.

I am currently trying to learn Salesforce and I'm going through the force.com workbook. Did I miss a whole section or something because I understand nothing about this section and it gives no instructions on how to do this section at all. I've gone down this list in the order from top to bottom. https://developer.salesforce.com/docs/atlas.en-us.workbook.meta/workbook/analytics_api_1.htm

Should I skip it? (I have no background in coding or anything technology based so I am learning all of this for the first time ever, though I did work in 2 jobs where I was a user of Salesforce as a CRM tool for sales)

Hello.  I'm new to Salesforce and am following the tutorials in the Force.com Workbook.  The lesson is to create a flow to add a Line Item to an existing Invoice when you press a custom button.  Instead of getting a new page for the new Line Item, I get the "URL no longer exists" page.

This is the URL on the error page:

https://na17.salesforce.com/flow/Add_Line_Item_from_Invoice_and_Update_Stock_Quantity%E2%80%8B?vInvoiceId=a01o0000001EMeC&retURL=/a01o0000001EMeC

And this is the URL in the custom Button definition to launch the flow:

/flow/Add_Line_Item_from_Invoice_and_Update_Stock_Quantity?vInvoiceId={!Invoice__c.Id}&saveURL=/{!Invoice__c.Id}&retURL=/{!Invoice__c.Id}

I'm only following the workbook instructions.  I would also appreciate help in finding the exact error message.

Thank You
