Alright, Instead of using Increment Column VI use the "EXCEL EASY TEXT.VI " to update your column name and make use of start and end index to control your column index. This will avoid the use of basic report generation API.
Looks like you have lots of column to update, but I can see that you have sequence inside sequence inside sequence, you can really modify the logic and come up with better ones.
Well in my earlier reply I meant use the EXCEL EASY TEXT VI to update the column names, and since you get the data from the database you can write data in a loop at once instead of writing into variable and then writing into excel sheet.Use "EXCEL EASY TABLE" to write the data into excel file at once, remember to properly program the start and end inputs.
Attaching the excel sheet generated from my program and see the wonders what we can do from NI report generation toolkit
Have attached some programs of my project
