Even though you are using index key 1 (but you have your fields in the wrong order), the LIKE part is your problem. Since i do not know the content of field lv_objek, i assume you filled it correctly.
If you search with an ESCAPE character you must obey some rules:
1. Use it ONLY in OPEN SQL (so not in NATIVE SQL).
2. Use it ONLY if the wildcard character, you need to use the ESCAPE for, has indeed special handling in ABAP, when being processed.
3. For the OPEN SQL wildcard characters % and _ you do NOT use the ESCAPE. The do NOT have special meaning.
