Data Archive for Customised Table

Dear All,

My requirement is to archive data to ADK file according to date selection and retention time is 6 years. ALV report should fetch data from Ztable and also from archived file as per date selection. I have created one Archive Object.

I have some questions:

1. what are the actual steps and prerequisite to archive data for customized table?

2. how to create content repository for data archive?

3. For write and delete program which function modules are to be used? 

4. Do i need to create new Logical file or I can use standard file ARCHIVE_DATA_FILE.

regards,

Mahadeo
