The technique I use with both the Addins Upload wizard as well as the AGS calls is to *always* is to update row 0 (LSF9) or row 1 (8.x). So if you look at a table that has 4 detail rows, and I need to update all 4, I would use 4 separate calls, always updating the "first" row on the form. The trick to that is that you need to delve into the form details (capturing AGS calls from Portal) to see what hidden fields need to be populated (often the PT-XXX fields) to make the update work. This technique then allows you to update the fields on detail forms which would otherwise require a page-down. Here's an example of how I use this technique with HR11 user fields: https://www.lawsonguru.co...th-Excel-Add-In.aspx
