Explanation
Adobe Campaign allows you to create and edit workflows using a graphical interface or an XML editor. You can also view and modify the properties of a workflow, such as its name, label, description, priority and login2
.
The login property of a workflow indicates the operator who created or scheduled the workflow. It is used for security and notification purposes. If the operator's access for the campaign instance has been revoked, then the workflow may fail or generate errors3.
To remove the error in your workflow, you need to replace the login property with an active operator's user ID and email address. The user ID and email address are separated by a colon (:) in the XML code. For example:
login="1234:[email protected]".

Adobe Campaign allows you to create queries that filter recipients based on various criteria, such as their profile attributes, delivery properties and tracking logs. You can use queries to segment your audience and target specific groups of recipients for your campaigns2.
To achieve the requirement of sending a follow-up email delivery to those customers who did not open the previous delivery labeled "New Offers", you need to create a query that filters recipients based on their product, package, delivery label and tracking logs. You need to use the Tracking Logs (trackingLog) dimension and check if it does not exist for each recipient. This means that there is no tracking information for opening or clicking on links in the previous delivery3.

The correct logic would be to select recipients based on product and package criteria and then check whether there is an absence of tracking logs for opens, indicating that the email was not opened. The expression "Tracking Logs (trackingLog): do not exist" serves this purpose by filtering out all recipients who have an open event in their tracking logs for the specified delivery.References:This explanation is derived from the standard practice of tracking recipient interactions in email marketing campaigns, where tracking logs are used to determine opens, clicks, and other recipient actions.

Explanation
Adobe Campaign allows you to send messages across different channels, such as email, SMS, push notifications, etc. You can also configure and schedule your deliveries according to your business needs and objectives2.
To ensure that the offers are controlled in a sequential send, you need to use an incremental query and apply the Capacity Typology rule3. An incremental query is a type of query that lets you select a subset of recipients based on a fixed number or a percentage. The Capacity Typology rule is a type of typology rule that lets you limit the number of messages sent per day for a specific channel.

Adobe Campaign provides several reporting tools that can help analyze and represent data for different purposes. Some of these tools are:
* Audit features: These features allow you to track and monitor user activities on various objects and folders in Adobe Campaign, such as deliveries, workflows, reports, etc. You can access them under Administration > Audit folder.
* logins.log file: This file records all the login attempts to Adobe Campaign server, including successful and failed logins. You can access it in the nlserver syslogd module.
* Delivery summary report: This report shows a summary of the delivery settings and statistics, such as target population, subject line, sender name, etc. You can access it in Adobe Creative Cloud.
This would allow you to export a report on user activities with various reporting tools within Adobe Campaign. You would be able to see how many times each report has been generated and how many unique users used it.

After clicking "Auto-Detect Format," the business practitioner should B. Verify the file format, specifically date formats that need to be set correctly.
While "Auto-Detect Format" can be helpful in identifying the format of the file, it is important to verify the file format, specifically date formats that need to be set correctly. This can help ensure that the data is loaded correctly and that there are no issues with the data.
