@JosephGagnon, I do not understand what do you mean by child and parent items. In case of duplicated keys you need to use a list and save all duplicated objects. After that you can iterate over list and add to a Map using some other method to generate keys. You can create new question, link to this one, and describe what to you want to achieve. Also provide an example how it should work for better understanding.

This was helpful. You showed me some neat tricks I did not know about. There is a problem though. Because the PARENT ITEM NUMBER is not always unique (see my explanation in the posting), I'm running into an issue where it's trying to insert duplicate keys into dataMap. I think dataMap values need to be a list of "row" entries, representing the child items (idenitfied by 2ND ITEM NUMBER).
