Hi,

I have a requirement to process only a single column(Ex:ID) and when i try to process this update the WO using this Id it is getting failed.obj-open-by-handle is getting failed with an error: unable to open an instance with the given inputs:xxx-xxx-xxx XXX-123. But when i include one more extra column to the excel and parse it and process it,i'm not getting any error and the Work object is opened and it is getting updated.

So is there any mandatory minimum no.of columns should be used to process a file listener?
