The Qty_Prod (quantity per product) variable in Indent BOM data set denotes the quantity of the component required to make one unit of the product. It only uses quantity per assembly information and does not take into account the scrap factor. The gross requirement (Gros_Req) variable in Summarized Parts data set will use the scrap factor along with other information (such as quantity on hand and quantity per) in computing the value. You can use the SUMMARYOUT= option in PROC BOM statement to create a Summarized Parts data set and find the gross and net requirements from the data set.
I hope this will answer your question. Please feel free to contact me if you have any questions.
Thanks and best wish,
