BOPF Code value check

Hello Colleagues,

I have implemented class /BOFU/CL_V_CODE_VALUES like described in this blog: http://scn.sap.com/community/abap/bopf/blog/2013/10/04/bopf-code-values-check#comment-644522

This works fine if the Domain has a check table or a check value. If I use a value range I get errors on all inputs.

I have domain "WORK_DAYS_YEAR" for storing the work days  a year can have. The Domain is a DEC(3). The possible value would be 0 and 366.

I have implemented the check class but I always get an error that my value is wrong no matter what I input.

Any idea on this?

Many thanks

Best regards

Roman
