Each infotype has a database table and a structure associated with it. As HR is related to time , we require old data as well as new data. The data we enter into the infotypes are automatically checked for accuracy and against the table entries. In simple, HR data is huge and to access data easily we require infotype. It is easy to group huge data using Infotypes.
