Copy DATA type ref to a hashed table

Hi gurus,

I'm trying to copy what I get from running a package ( ir_data type ref to data) into a hashed table:

FIELD-SYMBOLS:

                 <lt_data_ex> TYPE HASHED TABLE.

With this :

ir_data->* TO<lt_data_ex>.

And I am getting a runtime error,  due to a type conflict.

I guess I am doing something wrong, or is it posible this only can be done with standard table.?

Could you please help me on this?

Thanks in advance,

Ana
