you can do this in  a before/after update opportunity trigger

 

trigger tstopp on Opportunity(before update)

{

set<id> setoppIds = Trigger.newmap.keySet();

 

//now query the opportunity related records

//ex. for Products

 

list<OpportunityLineItem> lstLineItems = [select Id from OpportunityLineItem where OpportunityId in:setoppIds];

if(lstLineItems.size() > 0)

delete lstLineItems;

}
