CRM Callout - Phonecall Can't Update (The object can not be updated because it is read-only)

Hi Experts,

I am trying to update the Sender fields of a phonecall. Essentially, what I am trying to achieve is: When an Account is transfered to a new user, the Contacts and Activities  are transfered to that user to. Unfortunately, the Sender field in the Activity remains in the old ower's name and therefore still appears in their "My Activities". I wrote this callout to drill down through the Acctount=>Contact=>Activities and update the Activities Sender fields. The callout fails with an error code "8004022e" and error message "The object can not be updated because it is read-only because it is read-only".  

Any ideas,

Matt

@ Biffster007,

Yes it is only Phonecalls. I couldn't test faxes but emails & letters work OK.

Thanks,

Mroning,

Try retrieving all columns when you retrieve the phone call and try updating something else other than the 'from' field.  Something simply typed like a string field.

The phonecall is definitely active??

Also, what happens when you try and make the same change through the interface...success??

Cheers,
MH

Hi Biffster007,

Sorry for the long delay between posts. I am in the process of setting up a CRM test server so this callout has been pushed back until I get it up & running; I am thinking the end of next week. Thanks for your help so far.
