This needs clarification.
1) To be clear when you refer to parent and child that is:
FK
parent_tbl.fld <--> child_tbl.fld_fk
not parent and child tables in partitioning scheme?
2) What are the table schemas?
3) What is the code that is generating the error?
Overall it looks like this process needs a top to bottom audit to map
out what is actually being done versus what needs to be done.
Yes the tables were actually having parent and child table relationships, not the child/parent table in partitioning scheme. And the PK and FK are on columns - (ID, part_date) .The table is the daily range partitioned on column part_date.
The error we are seeing is as below in logs:-
