Synchronization Editor - Object scope for SAPUser having UserType =Dialog (BAPILOGOND_USTYP)

Hallo,

we have requirement to synchronize only "Dailog" SAPUser from target system. As not system  filter is supported, we need to add an object filter. Even with 2500 SAPUser, Synchronization Editor can't load the data from target system with BAPILOGOND_USTYP ='A' (Dialog User). If i do that same way with UserName, it works very good. Do someone have an idea or experience with such kind of filter?

Thank you
