Depreciation Meter/Validity (Infotype 1025) 
Definition
An infotype that lets you store information on the depreciation of qualifications and the validity of business event types.
Use
This information is used in the areas of personnel development, and personnel training and education. The infotype lets you specify the period of time after which a qualification or skill is no longer valid or has depreciated in value and consequently needs to be refreshed.
This, in turn, generates a training need for an employee. In Training and Event Management you can assign a validity period to a business event type. You also store information on prerequisite events and follow-up events for business event types. Once the validity period of a business event type expires, the corresponding relationship between the attendee and the business event that was created during follow-up processing becomes invalid. (This is the relationship B034 has attended event of type).
In Personnel Development the validity period you assign specifies the time period after which a qualification or skill (for example, a pilot's license) needs to be renewed or refreshed.
The depreciation meter specifies the period after which a qualification attained is worth only half its original value.
Structure
Infotype 1025 stores data on the validity period and depreciation meter of qualifications, and the validity of business event types. You can maintain validity data for event types in this infotype.
Integration
You maintain the validity duration of business event types in the Training and Event Management (PE) component. You can do so directly for the business event type or by accessing infotype maintenance.
You can maintain the validity period and depreciation meter for qualifications either in the master data catalog in Training and Event Management or in the qualifications catalog in the Personnel Development component. The data you maintain is stored in infotype 1025. However, you cannot actually maintain this data in the infotype.
