What causes this issue?

CASE &V1&.
WHEN '01'.
The variant for program &V2& was not specified. Specifying this variant
is useful if the program has no selection parameters.
If there are some selection parameters in the program, then the program
can only be run in the background with a variant. If this is the case
then it is best to maintain some parameters at this point, since
omitting to so so would mean that the program would fail to select any
data.
To receive all the dates/times that the program has been scheduled to
run, use the generic entry '*'.
WHEN '02'.
The parameter for the chosen task was not specified by the user. The
user must specify a parameter, since the program in question cannot
accept an empty parameter.
To receive all the dates/times that the program has been scheduled to
run, use the generic entry '*'.
ENDCASE.
