Add Show Activity Link to Customer Saved Search Results

By going to More Actions > Show Activity from the customer record, a pop-up window will display the customer's activities. A formula field can be added to a customer saved search that will go directly to this page, acting as a shortcut and saving the extra step of going through the customer record first. To do this, add this field on the Results tab of your saved search:

Field: Formula (Text)
Formula: '<A href="https://system.netsuite.com/app/crm/common/crmactivityhistory.nl?fkcol=kCompany&id='||{internalid}||'">Show Activity</A>'
Custom Label: Show Activity

Note: Please make a note of the URL used to access your NetSuite account. If the URL has something between "system" and "netsuite.com" (e.g. system.beta.netsuite.com), include that in the formula.
