Symptom

The statement COMPUTE EXACT allows operands of the types N, D and T at runtime although there is a syntax error if the operand types are known at compile time.

Reason and Prerequisites

The symptom can only occur if a NetWeaver 7.20 Kernel is used in a system that is of NetWeaver Release 7.10 or 7.11. (At the time of writing this, the NetWeaver 7.20 Kernel has not yet been released as a downward-compatible kernel for the NetWeaver Releases 7.10 and 7.11.)
In the NetWeaver Releases 7.10 and 7.11, the statement COMPUTE EXACT does not support operands of the types N, D and T. This is checked both at compile time and at runtime. The runtime check was missing in early 7.20 Kernels.
Solution

Use the NetWeaver 7.20 Kernel Patch specified in this note.
