Example please ?

Why don't you just compare components you want to compare ?

e.g.

in some loop...around loop

ASSIGN COMPONENT 'CUSTOMER' OF STRUCTURE <line> TO <field>.

ASSIGN COMPONENT 'CUSTOMER' OF STRUCTURE <line2> TO <field2>.

IF <field> <> <field2>.

..blahblah...

l_bool_not_equal = 'X'.

EXIT.

ENDIF.

Just loop thru everything and compare.

Not sure of your exact requirement. But if you need as what you have mentioned, try below logic.

1. Pass your field symbol to method CL_ABAP_STRUCTDESCR=>DESCRIBE_BY_DATA and get the reference.

2. Use get_ddic_field_list method of importing reference to get the list of fields

3. Create a new fieldcatalog by using above fields and add your new field to this fieldcatlog internal table(at the end).

4. Use cl_alv_table_create=>create_dynamic_table to create a dynamic internal table

5. Create a workarea for the above internal table.

You can use this new work area for your manipulation.
