Update campaign with the budget optimizer?

[ous]

I use the adwords API and I tried to update a campaign by activating
the budget optimizer but I got an error.

The campaign contains no adgroup or keywords and i made two calls :

- the first call, i updated EnableSeparateContentBids filed to false
and AdScheduler status to disabled value.

- the sencond call turn on the budget optimizer. this call failed and
i got the following message : --->Site targeting is incompatible with
budget optimizer. the error code was 92.

the error code (92) and the message doesn't match. I readed the
documentation and found this :
"This request attempts to enable separate content bids on an auto
bidder campaign, which is not allowed. This error code can also
indicate an incompatibility with ad scheduling and budget optimizer.
It can also be triggered by an attempt to turn budget optimizer on
while either separate content bidding or ad scheduling is on."

so, when i try to update the budget optimizer i get always the error.

i know anymore what must i do to be able to do my update.
i'm working on sandbox environement.

Please, can you answer me if you have an idea what is it.
thank you very much.

Hello,

I'm able to successfully set enabled the budget optimizer settings in
the Sandbox environment by making the following request (my id is
obviously different from what yours would be):

<updateCampaign>
<campaign>
<id>5971</id>
<budgetOptimizerSettings>
<bidCeiling>1000000</bidCeiling>
<enabled>true</enabled>
</budgetOptimizerSettings>
</campaign>
</updateCampaign>

Can you confirm that the update of the enable separate content bids
and the ad scheduler changes to the existing campaign were
successfully processed by making a call to getCampaign(id) and
checking the resulting Campaign object? Are you able to reproduce the
issue if you try to updateCampaign() with a freshly created campaign
that otherwise has default values?
