I'm trying to expedite the creation of an AF table in PI System Explorer. I have an excel spreadsheet of data that was provided to me which contains the information I need to add. I've created the columns for each column of data in excel. I have been attempting to copy/paste sets of rows from excel into System Explorer but it seems limited. Initially I tried to paste all 1800 or so rows into the table and it wouldn't go. I kept reducing the number of rows i attempted to paste until I was down to about 150 rows and that worked. However in order to continue pasting rows into the table I had to continuously decrease the number of rows I moved at once, until it got to the point that I system explorer just ignores me trying to add rows. Is there a workaround for this? I tried converting my excel spreadsheet to an XML file and do an import but I think the way excel coverts the sheet isn't compatible with PI AF as it always gives me an error. Any ideas on how to get this information into PI? Thanks!
