When maintaining classification data for dangerous goods management, you assign a UN listed substance to the dangerous goods classification for each dangerous goods regulation. The UN listed substance contains dangerous goods legal data for an identification number In order to specify the degree of risk more exactly, you must enter the risk potential (dangerous goods letter, packing group) when assigning. When doing so, you must check whether this risk potential also exists for the UN listed substance.
This function exit enables you to set up your own checks when maintaining data for dangerous goods classification. Normally the R/3 System checks whether the risk potential exists in the THM071 Customizing table. The function exit also allows you to perform your own check against the legal data stored within a UN listed substance. If the function exit is not activated, the system checks against all three additional tables for dangerous goods (transport approval, packaging code approval, risk classification), which is the standard procedure, and issues a warning if there are any errors.
In addition the system can also check whether the assignment of the hazard-inducing substances is correct. As a standard procedure, the system checks whether the descriptions for the hazard-inducers are specified in all phrase items when the hazard-inducers are assigned.
The customer exit can be found in the function group XC1A. You call it in the function module C10U_USER_EXIT_CALL. The standard procedure (when not activating the function exit) can be found in the function module C10U_USER_EXIT_SUBSTITUTE.

As an alternative to returning the message parameters, you can perform message handling in the function exit itself.
