EEM - Dynamic Values in EEM-Scripts ?

Hi,

is it possible to put a dynamic value in a recorded EEM-Script ?

If yes, does someone have a sample-code for it ?

We need it for a SAPGui-Script.

In the script there is a date-field to be filled and it should be 'in the last 4 weeks',

means, that the the script should fill in the timerange-field with from '4 weeks ago' to 'now'...
