What do you mean by the selected item?  The item w/ the selected check-box marked - or the highlighted row.  Please clarify.

Hi @angierowley75  and @jechang 

It appears to be that what ever line is highlighted regardless of the check box, it is only showing the items on the highlighted line. I tested this in my local and I get the same results as @jechang. @angierowley75  Is this a possible bug? It seems that it should be showing the inventory ID’s for the checked box lines and not the highlighted ones. 

You are correct - the selected lines (not highlighted) lines should populating the grid in the pop-up window.

I would recommend you contact support - please make sure you provide them your Build #.  I have a very recent build and was not able to duplicate your issue.  It is feasible the issues has already been resolved w/ in update.

@jechang  I am on build 22.108.0024 if that helps you. You could look at release notes after that build or as @angierowley75  suggested, put in a support ticket with your partner or directly with Acumatica.
