How can you append data extensions?

You can bring fields of multiple Data Extensions (DEs) together, and add the rows of multiple Data Extensions together in one new Data Extension.

When do you need to use it?

When you have multiple sources of similar data. For instance, you have 4 DEs with contact information (first name, last name, email), and want to create one new DE that contains the contacts in these 4 DEs.

How can you do it?

• In case you have multiple sources of similar data that you want to append in the same target data extension, you can do so by using the tabs (Append Data Extensions) functionality in DESelect.
• Click on the + icon to create a new tab
• Each tab can contain its own source data extensions/data views and filters
• The data of the different tabs will be appended and written to one target data extension.
