Workbook with variant: generation of doc. with variable val. not possible

What causes this issue?

You want to broadcast a workbook using the distribution type <ZK>Broadca
st E-mail (Bursting)</> , where the input variable for the workbook
changes for each receiver (option <ZK>Generate Document with Variable
Value</>). This is not technically possible if the variables for the
workbook are filled using a variant (see <ZK>Workbook Precalculation</>
tab page).

System Response

The broadcast setting is inconsistent and can neither be saved or
executed.

How to fix this error?

Explicitly determine the variables for the workbook (not with a variant)
or choose the option <ZK>Send Document Unchanged</> for the receiver
determination.
