Activites can't be deleted
Hello SAP gurus,
Could you please help me with following problem: we need to enable activities deletion in CRM 2007, but we can't delete some activities. (not all) and we are not able to find any criteria what activities can't be deleted.
Could you give me any info what activities can't be deleted? I checked already that it is not problem of follow up document: none of my activites have follow ups.
