*****************************************************

##Common issues## ( during delta load by a ABAP CDC ):

1. Change data capture of I_xxx is broken   -- I_xxx is the name of a CDS view
   Message no. SODQ666
   Or
   E:RSODP_ABAP_CDS:341
2. Change data capture (CDC) annotations of I_xxx changed incompatibly
3. The database cursor is invalid
4. No new delta data comes into UNIT of ODQMON even  there are newly created or changed records in source CDS view
5. Transaction DHCDCMON -> Application log shows one of the following messages:
   a) User  is not authorized to replicate from CDS view xxx for subscriber ODP / Message no. DHCDC_AUTH008
   b) User xxx is not authorized to process CDS view xxx for subscriber ODP / Message no. DHCDC_AUTH008
   c) User xxx is not authorized to use the observer process Message no. DHCDC_AUTH004
   d) User xxx is not authorized to stop recording changes for subscriber ODP  DHCDC_AUTH001
6. Error reading CDC annotations: mapping field does not exist
7. Cannot start ACP daemon (client XXX)
8. Invalid Entry : No entry in ODQSSN found for subscription
9. Cannot subscribe to object <table_name>; not all triggers or logging tables exist 

##Common questions##

1. Question1: How the deleted record looks like during delta load?
   
2. Question2: Will the change on table with role LEFT_OUTER_TO_ONE_JOIN also trigger the delta data for the CDC?
   
3. Question3: What kind of operation type or update type can CDC provide?
