ABAP Select data from SAP table D010BEHV into internal table

So we all know S/4Hana is the latest version and the future of SAP but what about the selecting data from hana tables, is it 5he same and what do tables like D010BEHV look like in an S/4 system. If you havent seen or logged into an S/4Hana system you might be surprised at how similar it looks to the previous ERP/ECC version. Infact when using the gui it is difficult to tell the difference, and selecting data from database tables the same is true. Infact even for tables that have been replaced in hana, SAP have purposfully created versions of the old/original tables for backward compatability. This means your existing ABAP code will still work while you implement changes that take advantage of the new functionality and Hana in-memory tables.

Below is a number of ABAP code snippets to demonstrate how to select data from SAP D010BEHV table and store it within an internal table, including using the newer @DATA inline declaration methods. It also shows you various ways to process this data using ABAP work area, inline declaration or field symbols including executing all the relevant CONVERSION_EXIT routines specific to D010BEHV. See here for more generic Select statement tips.
