Generation of runtime objects fails

Hi,

I have issues with generation of runtime objects in SEGW t-code (on NW 7.4 , SAP_GWFND SP 09, upgraded from NW 7.2 with IW_BEP):

If I create new project, I add some test entities and sets, then I click on generation button and I got very nice and informative message:

Generation of runtime objects for project 'ZGENTEST' failed

Internal error occurred

Syntax Error: 'Internal error occurred at Initialize in source co'

when I try to generate objects for older projects with runtime objects I've got another very informative message:

Generation of runtime objects for project 'YMF_PLM' failed

Model Provider Base Class 'YCL_YMF_PLM_MPC' generated successfully

Failed to create data provider class (Message no. /IWBEP/MC_SB_DPC_ADM024)

Do anyone knows what can cause this issue?

Thanks Jiri
