HK can only be used to pass key fields. As an alternative, you could use an AGS call as well as a DME call. However, an AGS call would not display the form itself (AGS is used to process a form via HTTP, not display a form). I'd recommend a DME call to list of the messages for the specific, with each detail line having a link to MA60. But, what you'll find out is that if you have a lot of lines, you start having to deal with paging. Which then leads to using Design Studio to build a Portal Page to handle the query and paging, and then linking the Portal Page to an MA60 form. If you look at this article (see https://www.danalytics.co...archive/2007-12.htm, you will see a similar concept of a Portal Page combined with a customized form. Since a Portal Page has access to the parameters passed to it, you would be able to pass those parameters via LSN, and display the appropriate vendor messages.
