Determination of Secondary Data 
Determination of Secondary Data
Use
In secondary data determination, you can carry out the following activities:
The existing R and S records for individual constituents are transferred via a defined interface to an external system in which the R and S records for compositions that contain these constituents are determined. The derived secondary data are then transferred back to the R/3 System.
Data from the R/3 component Product Safety can be updated using an import. If these data were used to determine secondary data, you can check these secondary data and derive them again if necessary.
Features
The derivation and checking of secondary data is carried out using function modules that are integrated in user exit management in Customizing for Product Safety. You can also develop your own user exits in the same way.
Normally, secondary data can be derived and checked in the R/3 System or in an external system.
In the R/3 standard system, there is an example of secondary data determination and checking for notification status.
