I have written earlier about cloning or copying existing records. Please see the article Using the COM API to Clone a Record.
This article provides a worked example on how you can use that article to add a button to the opportunity summary screen that will copy an existing opportunity record and start a new workflow.
To do this we need to create a New Button group linked to the opportunitysummary system action.
Administration -> Advanced Customization -> Button Groups
The button needs to call an ASP page. I have called mine cloneoppo.asp.
The code will need to copy the record, save it and then redirect the page to the list of opportunities to show the new opportunity has been created.
The ASP file was saved as cloneoppo.asp uder the CustomPages folder e.g.
C:\Program Files\Sage\CRM\[installname]\WWWRoot\CustomPages\cloneoppo.asp
"); //copy the data from the first record to the second e = new Enumerator(FirstRecord); while (e.item()) { NewRecord(e.item()) = FirstRecord(e.item()) e.moveNext(); } //set the fields and properties unique to the new record NewRecord.oppo_description = NewRecord.oppo_description +"- cloned"; NewRecord.oppo_stage = "Lead"; NewRecord.SetWorkflowInfo("Opportunity Workflow", "Lead"); NewRecord.SaveChanges(); //Redirects to List of Opportunities Response.Redirect(CRM.URL(184)); %>
