Datacolumn in SendMail-Action

i would like to enter datacolumns in MailSubject, but I get this message even though the source table is filled.
Parameters work. What am I doing wrong?



Columns are not available because a column can have many values which creates ambiguity.

However, you can put the “Send email” action in a module, define module parameters that would correspond to column names, and then use the “Iterate” action to call the module and assign its parameters with column values.

The parameters can be used in the subject expression.

Hi Dmitry,
