There is a predefined InfoSet called CRM_MKTTG_BP_BIRTHDATE
SAP writes that I can select BPs by relative birthdates (e.g. tomorrow...): http://help.sap.com/saphelp_crm40sr1/helpdata/en/d2/1d13bd5cd34040a2f03b622d121a43/content.htm
But when I'm adding a filter (EQ +1D for tommorow) to the Attribute in the Segment Builder the TargetGroup has no entries.
Where is the mistake?
