Change Log active despite Data Class "APPL0" or "APPL1"

Hi All,

I am doing upgradation from  the ECC EHP6 to EHP7 on HANA database ,when I run the code inspector in the new version for the custom impacted objects , I got the list of custom objects which are having error :

Below are the error which I got through SCI :

1. Change Log active despite Data Class "APPL0" or "APPL1"

2. READ .. BINARY SEARCH for result of statement at Method

3. DELETE ADJACENT DUPLICATES for result of statement at Method

4. LOOP AT itab. AT ... ENDAT. for result of statement at Include

5. Large table <dbtable>I: No WHERE condition

6.  Different number of parameters in FORM and PERFORM (routine: <routine name>, number of formal parameters: 0, number of actual parameters: 1)

7.  Use of Native SQL

8. The authorization object <objname> requires 10 authorization fields.

Could you please provide how to resolve the above errors in the SAP HANA data base in ECC .

Thank you.
