Time Evaluation in SAP

Time Evaluation in SAP

In the initial days of my Career , i used to have a lot of questions on Positive and Negative Time evaluation, Time evaluation with and without clock time, and  a lot of questions between the different schema TM00, TM04 etc.

Over a period of time, i got answers to most of my questions.
Here i am sharing those.

The basic difference positive and negative time evaluation would be , what date is being captured and from where.
In negative time evaluation, only employee planned working hours are taken from Daily Work Schedule, and employee swipe in and swipe out data are not used or are not required.
Where as in positive time evaluation, Employee swipe in and Swipe out data from time terminals are used. So in a day an employee can have many clock in and clock out times. And normally only the first clock in and last clock out are considered.

And coming to the schema, there are only for reference. We have two main schema TM00 - Time evaluation with clock times, which i am calling as Positive time evaluation and TM04 -Time evaluation without clock times. You can also use TM00 to configure a negative time evaluation and similarly you can use TM04 for positive time evaluation. You can also have a schema , which does both.

It all bottoms down to the requirements, which is nothing but the expectations from the end user and the business processes.

Of course there are some functions which are specific to positive and negative time evaluations.
