Need ABAP sample code

[Former Member]

I need code to hide ABAP source code and protect it for further references.

Hi you can just hide the codes as

Put this code in the first line of the editor.

*@#@@[SAP]

ensure that this should be the only code in first line first column, There is no easy way to get back codes easily. but a experienced Basis guy can retrieve it...

Take backup before trial......

If u want to hide really codes at all, use C++ classes.

Hope this will help u.

check below sample program.

report zsam_hide no standard page heading.

************************************************************************

• This program hides any ABAP's source code and protects it with a

• password in this source code.

*

• After hiding, you can still run the abap (the load version is intact)

• but it cannot be displayed, edited, traced, transported or generated.

*

• If the ABAP is not hidden, the program hides it, if it is hidden, it

• unhide it.

• Remember to hide this program first!

Even you can implement a Exit <b>EXIT_SAPLS38E_001</b> to hide or protect ABAP source code without direct updates to SAP tables

Check if you can use Authorization objects for display purpose also...
