My first post, but my millionth read on this great site!
I am looking to use TTS to remove old data partitions from a table. I have tried a test case so that I can understand how it works. Found this example in Oracle Support and cannot get it to work. Doc ID 731559.1
Below code, creates a date range partitioned table. The goal is to move *the oldest* partition (FY2017 stored in tablespace ttsdat1) to a new database.
The transportable set check fails and I do not know why. See bottom for the failures.
What am I doing wrong? Why does the transport check fail?
I'm on 19c, ASM and Enterprise Edition.

The rule with partitioned tables is:
From the docs:
https://docs.oracle.com/en/database/oracle/oracle-database/18/admin/transporting-data.html#GUID-1901E9C3-8FCE-4D4E-AB65-34D703474E52 The tablespace set you want to copy must contain either all partitions of a partitioned table, or none of the partitions of a partitioned table. If you want to transport a subset of a partition table, you must exchange the partitions into tables.I will start with your position and work from there (I took the liberty of making your insert script more efficient)

ORA-39901: Partitioned table MCDONAC.TXNS is partially contained in the transportable set.

So a couple of things to sort out here
1) Get the archive partition into its own table
SQL> create table archive_txns_2017 tablespace ttsdat1
2 for exchange with table txns;
Table created.
SQL> alter table txns exchange partition fy2017 with table archive_txns_2017;
Table altered.

but there still seems to be a problem. See below
2) Fix the default attributes
As well as the partition definitions, there is a default tablespace setting for the table, which still points to TTSDATA1. We need to fix that.
SQL> alter table txns modify default attributes tablespace ttsdat2;
Table altered.
SQL> EXECUTE sys.DBMS_TTS.TRANSPORT_SET_CHECK('ttsdat1', TRUE);
PL/SQL procedure successfully completed.
SQL>
SQL> SELECT * FROM sys.transport_set_violations order by 1;
no rows selected
and we're done.
