I am working in IBM Maximo 7.6 and I am using Eclipse to create reports using BIRT Designer. I am working with a copy of the out-of-the-box report called "maintaincost_by_system.rptdesign". I would like the report to also show a breakdown of how we arrived at the total cost. That is, it should also show the components of Total Cost, including labor cost, material cost, and service cost. When I preview the report in Eclipse, it looks good at the top level and it shows me the cost breakdown; however, as I drill down, it is no longer showing me the cost break down; it only shows total cost. What can I do to fix this error?
