Dynamic programming is needed for that.
Assign the table reference to a field symbol, and then loop into it.
Something like this:
FIELD-SYMBOLS <lt> TYPE ANY TABLE.
FIELD-SYMBOLS <ls> TYPE ANY.
ASSIGN gs_para-ref->* TO <lt>.
LOOP AT <lt> ASSIGNING <ls>.
"see values in debug mode
"use ASSIGN COMPONENT to get specific field value from <ls>
ENDLOOP.
