What is hot data?
Current data is known as the data appropriate to the operations of application objects, which are required in day-to day-business transactions. The application logic regulates when current data turns historical by using its knowledge about the life cycle of the object. From a business point of view, the application logic authenticates the conditions at the object level based on the status, execution of existence checks, and verification of cross-object dependencies. Current data is preserved in the current area.
Examples of current data: Documents meant for an ongoing project, items cleared few months ago Open FI items, purchase orders which are undelivered, sales documents of sales cycle which is still in progress, and IDocs which need to be processed.
What is cold data?
Historical data is that data which has not been used for day-to day-business transactions. Historical data is not visible to ABAP applications, by default. It is no longer rationalized from a business point of view. The application logic regulates when current data turns historical by utilizing the knowledge about the lifecycle of an object. The application logic authenticates the conditions at an object level from a business point of view, and is based on the status, executing existence checks, and verifying cross object dependencies. Historical data is generally preserved in the historical area.
Examples of historical data: Cleared FI items which have been posted two years prior to the current fiscal year, material documents for one period older than the current closed period, processed IDocs, and application logs after X number of days.
