EXPORT / IMPORT value TYPE REF

Hi Colleagues,

I write an enhancement.

The tx creates an ALV list. My enhancement in the same tx must determine the selected lines from the list. After creating the list I need the name from ALV, I want to store it with EXPORT and to read it in the enhancement with IMPORT. But EXPORT isn't possible because the value has TYPE REF ... Do You have any suggestions to make EXPORT / IMPORT possible ?

Thanks a lot for Your help !

Peter
