Diagnosis
You are using an object characteristic that is not supported in any IPCscenario.

System Response
Characteristics that are not supported do not receive any values fromthe call environment and therefore have no value in the read access, soinconsistencies may result. Write access to data from the callingenvironment is fundamentally not possible (exceptions: STPO-MENGE,SDCOM-VKOND).

Procedure
If you want read access to the reference field, check whether itis possible in your scenario to enter the corresponding SCE context(table name, table field, value) in the IPC-calling application. Forcorresponding instructions, see the online documentation.
