I would recommend taking a look at a quick action vs using a custom button url hack since they do not work in Lightning experience and are not supported by salesforce and therefor could break without notice but if you want to continue with the URL hack then you need to change your paramaters to set both the id and the name and also include CF before the field ID for custom fields: {!URLFOR($Action.Rep_Expense__c.New,null,[CF00No0000000lFwWEAU=Contact.Id, CF00No0000000lFwWEAU_lkid=Contact.Name],true)}

  • I used the code and got the below error. SObject row was retrieved via SOQL without querying the requested field: Contact.Name

  • @Dinesh is this button be placed on a visualforce page and if yes does that visualforce page have access to the contact name?

  • @Dinesh but do you specifically have the Name field rendered on the page?

  • Yes, I have rendered Name field in page. I created custom button with this code "/a08/e?CF00No0000000lFwW={!Contact.Name}&CF00No0000000lFwW_lkid={!Contact.Id}" and now its working fine. Thanks Jenny for helping me to fix the issue.

You can do this with URL Hacking.

As a quick recap – URL hacking is the process of pre-populating data in a new record with data from a record you are currently working off using a custom button to launch this new record.
