Hi Luis,
oh sorry i meant to say:
Do you have any other idea how to force the the RAPID application to get the data directly from db? Cause we are having another issue when saving the root entity and reading it directly after that. The correct data is stored on DB, but the root entity does not contain the recently set data anymore.
Yeah we have tried it this way. And as of now we do not see any other option than opening a SAP incident. 
Thanks,
Wladimir
