Cons unit &1: Looking in physical file &4

What causes this issue?

Data transfer method 'flexible upload' is assigned to consolidation
unit &V1& in version &V2&. Upload method &V3& is used.
Because no logical filename is assigned, at run-time the system could
not automatically determine the physical path of the file.
However, in the meantime, a physical file was specified for the
flexible upload.
