Hi Hashmi,
(1) The first SAP Note you are talking about is 1127210 - Change documents for AccessControlList. Kindly follow the steps as specified in the SAP Note. Do exactly as mentioned in the SAP Note. It is in regards to the Change Documents; using the SCDO will generate the update function modules that will help in logging the changes to the tables CDHDR & CDPOS.
