Passing a class instance between external sap modes

former_member205645 — Fri, 13 Apr 2012 08:37:57 GMT

Hello Gurus,

do you guys know if it possible to pass a class instance from one external mode to another one? I tried converting the memory adress intro a string and writing it on the database but it won't let me convert a class reference. Any ideas?

Kind regards,

Ioan.

Hi Loan,

You could try using shared objects to share the data between external modes of SAP.

Hi loan,

Just found a useful link for shared objects. Using shared objects, you will have to make your class 'Shared enabled'. Then you have to create a memory area and attach the class as root class.

Using the methods of memory area class you can share the instance of your class.

Let me know if some more help is needed.

Jaspreet
