Functionality
This function module is used as a template for check and formattingfunctions that you can define for injury/illness log entry keysdepending on the injury/illness log entry type.
The function module is also available as a reference function module fordefining the interface of the user exit category FAL_SCATCH.

Example
The following implementation example works with the following numberrange intervals:
00001000000000000000 to 00009999999999999999 (internal)
A to ZZZZZZZZZZZZZZZZZZZZ (external)
*"*"Local interface:
*" IMPORTING
*" VALUE(I_FAID_TO_CHK) LIKE CCIHT_FAL-FAID
*" VALUE(I_FATYPE) LIKE CCIHT_FAL-FATYPE
*" VALUE(I_PLANT) LIKE CCIHT_FAL-FAPLANT OPTIONAL
*" VALUE(I_FLG_WANT_KEY_FORMAT) TYPE ESP1_BOOLEAN

*" EXPORTING
*" VALUE(E_FAID_CHKD_AND_FORMD) LIKE CCIHT_FAL-FAID

Notes
In Customizing for Occupational Health, you can assign a userexit name for every injury/illness log entry type in the IMG activitySpecify Injury/Illness Log Entry Types. Youmust have already created this user exit name in Customizing forBasic Data and Tools under Manage User Exits and assignedit to a function module.
In addition, under Specify Injury/Illness Log Entry Types you canassign an internal or external number range interval of the number rangeobject CBIHN_FAID for every injury/illness log entry type.
Note that when you use a formatting routine, it must be compatible withthe definition of the number range intervals.
If you write your own check function, its interface must match theinterface of the reference function module.
