Can you check if there is any Trust and Validation rule configured ?
There is no trust and validation rule configured.Even I have tried
by configuring trust and validation rule by degrading trust by 10%
but still not working.
Seems it is surviving by latest last_update_date record in xref.
How I can avoid survivorship by latest last_update_Date in xref.
The only way out for this is to use, Post Merge UserExits to determine which value to survive and accordingly update.
"survivorship by latest src_lud/last_update_Date in xref" is the first survivorship rule
is there any way to bypass this rule for a particular column only of a table so that trust and validation rule can work?
