I am using the Transformation Executor to group data rows to be written to Excel spreadsheets (50 to 60 different excel files). The data in the spreadsheets always contains one additional row that should be in the next sequential spreadsheet. The grouping should break and start a new excel file (which it does) but it always includes one row from the next sequential file. Is this a bug or is there a way to fix this? I want to say, "Group the rows to send... minus one." Thank you in advance for your help.
