User
Interfaces 
The Cross-Application Time Sheet (SAP CATS) is available in different user interfaces. This enables you to tailor time recording to suit your requirements.
The independent user interfaces have the following characteristics that differentiate them from the enhancing user interfaces:
· The data entry screen provides an overview of a complete data entry period.
· You can access data that has already been entered and correct, supplement, or delete it.
The enhancing user interfaces enable your employees to record data quickly wherever they are. If you want to display or change data that you entered using an enhancing user interface, you can use one of the independent user interfaces. You can combine any independent and enhancing user interfaces.
The graphic displays the independent and enhancing user interfaces of the time sheet in relation to the CATS application. Although the user interfaces are suited to different data entry requirements, they all use the same application logic and save data in the same database table.
Independent User Interfaces
CATS classic is the original user interface of the Cross-Application Time Sheet in the SAP R/3 System. It is particularly suited to users that also use the SAP R/3 System to complete other tasks. CATS classic is the most suitable user interface for entering working times for multiple personnel numbers, for example, by secretaries.
CATS regular offers a similar data entry screen and comparable features to CATS classic. However, this user interface has been optimized for use as an Employee Self-Service (ESS) application in a Web browser.
The data entry screen for CATS notebook is similar to that of CATS classic and CATS regular. CATS notebook also runs in the Web browser. CATS notebook is designed for use with notebooks, and is particularly suited to employees who have to travel a lot and cannot always have a connection to the SAP R/3 system to record their working times. CATS notebook saves the working times entered in a separate data store on the notebook. The next time CATS notebook is connected to SAP R/3, it synchronizes this data store with the CATS database in SAP R/3.
CATS for service providers provides an alternative to the data entry screen that is available with CATS classic, CATS regular, and CATS notebook. The data entry screen for CATS for service providers is based on recording billable services, and therefore does not resemble a traditional paper timesheet. CATS for service providers enables you to specify basic data that is valid for more than one day. You can then record task components (such as miles/kms driven, overtime, and so on). See Task Type, Component, and Level. The following restriction currently exists when combining CATS for service providers with other user interfaces of the Time Sheet: You can only display and not change data that you entered with CATS for service providers in the other independent user interfaces. You can only display and not change data that you entered with other user interfaces in CATS for service providers.
Enhancing User Interfaces
CATS instant is an iView and runs in an enterprise portal. It enables you to enter your current tasks or working times immediately. CATS instant is aimed primarily at users who have to record billable tasks. Such users may need to record the time they have spent on individual tasks accurately and at several times during the day. This iView enables users to record their working times easily and quickly. A worklist, from which users can choose the most important account assignment objects, is available for entering tasks.
CATS calendar is an iView and runs in an enterprise portal. It enables you to see at a glance on which days in a specified period, you still need to record working times. It displays the days of this period in the form of a calendar. The color used to highlight a day indicates whether you still need to record any working times. To use CATS regular to record working times, click on the relevant week in the calendar.
CATS phone is a WAP application and runs on WAP-enabled cell telephones. Similarly to CATS instant, it is aimed primarily at users who have to record billable tasks. In addition, it is primarily aimed at employees who have to travel a lot and visit several customers each day. CATS phone enables these employees to enter their tasks quickly as they go along. A worklist, from which users can choose the most important account assignment objects, is available for entering tasks.
