Delivery Class in ABAP Tables

In Data Class we have specified the Type of Data we will be using for our table, in Size Category we have declared the expected Volume of Data we will be saving. Now, we need to define the way the Data in the table behaves. It means whether data can be moved from one Landscape/system to other or not. It is achieved using Delivery Class in ABAP Tables.

*NOTE: Although the Delivery Class is declared before Data Class and Size Category, still it is advisable to read about it after them.

Definition

A delivery class defines:

  • Transport control of Data within Landscapes and customer systems
  • Transport control of Data for an installation or upgrade
  • Transport control of Data of client copy
  • Data can be maintained in Extended Table Maintenance [SM30] or not.

In short we can say a delivery class determines whether data of the table can be maintained & transported or not.
