Error in cell splitter node

When the flow runs automatically (on schedule), I get a warning message “Input table doesn’t contain specified column name” and the flow is not executable but when I run it manually it runs normally.
what’s the issue and how I can solve it?

Thanks in advance.

Hi @Mai_Nashaat , it’s difficult to know without being able to see your workflow. From the title, I gather that it is the Cell Splitter node that is producing this message. It is complaining that a column name doesn’t exist, so to debug, the first step might be to try to see what the input data looks like prior to the Cell Splitter. To do this, can you perhaps add an Excel Writer or other file writer to output a copy of the table to a file. You can then manually inspect that file to see what columns are present when it runs on the schedule and gives that error.
