How to get informations about data types in ABAP using descriptors?

Hi everyone! 👋

In this video, we explore how to retrieve information about ABAP data types dynamically! 🛠️ Using the CL_ABAP_TYPEDESCR class and its specialized subclasses like CL_ABAP_ELEMDESCR, CL_ABAP_STRUCTDESCR, and CL_ABAP_TABLEDESCR, you'll learn how to describe data at runtime. 🚀

We demonstrate how to use methods like DESCRIBE_BY_DATA 📄 and leverage the CAST operator 🔄 to work with specific type details. This approach is perfect for analyzing structures, tables, and elementary types efficiently! 📊

So I hope you will enjoy! ✨😊
