Parameter passing is inconsistent

What causes this issue?

The transfer parameters of this function module are inconsistent:
The parameter iv_subdir_levels has the value &V1&. The values of the
parameters iv_subdir1 to iv_subdir6 mean that it can only have the
value &V2&.

System Response

The system issues an error message and will not allow you to continue with this transaction until the error is resolved.

How to fix this error?

Call the function module with consistent parameters.
