Value is multiplied by two

Hello guys, I’m having a problem with reports in SSRS the qty is showing double its as it multiplied by two and other circled values are also what is the problem
the qty value must be

A couple of things to check are.

  1. Is there a duplicated join in your RDD.

  2. Is the data in the detail group

yes you are right it’s an rdd issue instead of output I must set it as definition only,
thanks bro
