Costplan breakdowns are double createdIssue After creation of cost plans for a certain project, the costplan breakdowns are created twice.Create a cost plan for the project for each month of Fiscal year, Ideally it should create 12 costplan breakdowns, but it creates 24 costplan breakdowns. this can be observed when you try to deleted the cost plan related to a project, the window shows 24 cost plans. If the cost plan is deleted and then you try to delete the project itself. it still shows 12 costplans breakdown left.Releasenot specific to any releaseResolutionthis is an expected behaviour by design.Say if you create 5 cost plans spanning for 1 year, then 60 requirement type breakdown + 12 task type breakdown will be there.Requirement type breakdown is at cost plan level and Task type breakdown is at task level.So when you delete a cost plan, only the related breakdown records will delete.But when you delete the project, all the records related to cost plan + additional 12 task type breakdown records associated with project will be deleted.
