How to find details of replication errors

Hi Experts,

I've created a replication configuration and everything seems to work fine. But when I tried to add table CDHDR, an error occured, see below:

Start of function - Access plan calculation 021 - on 25.04.2015 at 14:03:36

Access plan for CDHDR is being calculated (ID 00001, 8.000.000 blocks)

Z_CDHDR_021: Access plan could not be calculated, delimitation is not possible

Access plan calculation failed

End of function - Access plan calculation 021 - on 25.04.2015 at 14:03:42

How can I find more information about this error? Looking at ST22 on SLT and source system, both show no dumps.

Thanks and regards,

Roberto Falk
