Hi Florent,
thanks for your response.
After the validation/approval (content, etc) offers are published through a standard workflow to the live environment. During this pulishing-process all offers are not available for the defined time frame.
Use Case:
Step 1: Offer A and Offer B are allready published and live.
Step 2: Offer A is being edited and passed the approval process.
Step 3: The updated Offer A is automatically published to live --> during that process the the outdated Offer A, which is live untill the updated offer A is finally published, and Offer B are not available.
I hope to give the full understanding 
BR, Robert
