Estimate and Actual are different and causing PJ. - response (3) by BPP

@Dieter:  Yes it is same as SPOLISETTI question. 
When we first got this problem we suggested the same to the users but they are so tough on not changing their query.  They are tied to the idea that why it is working on Prod but changed suddenly on QA.. I cannot find anwser to convince them and I cannot get this query where it was.     I see changing it to outer join is way to go, we will have another chat with our dvlpr's.. 
Meanwhile If SPOLISETTI or I find anyting will let you all know..
