I tried with attribute real-update="no" alongwith enforce-ri="yes" & what it did was insert all children associated with the very first parent.Also when i remove the row-map-cache-file.The result is the same just that it takes a lot of time to deploy.But the issue is the same that it does not deploy all the children of the remaining parents.Also the DCR's are not custom types but interwoven types.Please let me know any other changes can be incorporated.
