Warning in Load External Forecast

Hi everyone,

while load external forecast with "Load Interface File for Import" and "Load Planning data from flat files" process the scheduled process "Load Planning data from flat files" gives me a warning.

The log of the scheduled process show this: "As we are unable to derive the BO list, setting status to Warning and not submitting the collection jobset."

I report that I was previously able to load an external forecast by compiling the file the same way, changing only the item name and forecast designator references.

How we can fix this error ? what is the cause ?

Regards
