Diagnosis
The scanner found a program with customer extensions and these customerextensions do not fullfill the rules of Unicode compatibility of ABAP6.10.

Procedure
Proposal A
There is no need, that all programs in this system are Unicode-enablednow.
As your include files work together with original SAP code, that isknown to be simple, you can switch off the Unicode flag.
Until this has not been done, the program will not work. As thescanner does not know, wether this is an important program or a lessimportant program, the impact on the system is not known.
