Can you edit AMDP class in the SAP GUI?

No. You can�t edit ABAP Managed Database Procedures (AMDP) class in the SAP GUI. If you try to edit an AMDP class called ZCL_DEMO in SAP GUI using SE24 transaction code, you will get an error "Class ZCL_DEMO contains stored procedures which cannot be changed in SAP GUI". Since you can�t edit AMDP class in SAP GUI you need to use ABAP Development Tools (Eclipse or HANA Studio).
