Excel Reader Node uses historical data when Raw Data File is missing.

I create a monthly report which uses new raw data each month. The raw data folder is filled with about 17 files. Only the files to be used for the current months reporting are within that folder. No historical data.

I then uses a row filter node to filter down to the raw data file that the Excel Reader node will read in. (There is a “Table to Row Variable” and “String to Path” node between the row filter and excel reader as well)

The raw data file was missing from the folder, but the Excel Reader node still created a table. It looks like the data is from a previous months raw data file, with a date column that is created to match the current months reporting. (we have no idea how the date column is created)

Will the excel reader node read from cached data in memory if the file its supposed to read is missing? Is there a way to turn this off?

Any help would definitely be appreciated. Thank you!
