ALTER TABLE TRAINING_MASTER
ADD CONSTRAINT MyTable_ForeignTableID_fk FOREIGN KEY (

First you need to fix the grants, obviously using a user with rights to do so:

SQL

GRANT REFERENCES ON TheOtherSchema.TheOtherTable TO MySchemaUser

Then you add the constraint on your table

SQL

ALTER TABLE MyTable
  ADD CONSTRAINT MyTable_ForeignTableID_fk FOREIGN KEY (
    ForeignTableID
  ) REFERENCES TheOtherSchema.TheOtherTable(
    ForeignTableID
  )
/

TWO USERS

First User EBMSPTS second user TESTNEW...

TABLE NAME TRAINING_MASTER

GRANT REFERENCES ON TESTNEW.TRAINING_MASTER TO TESTNEW;

*** success

ALTER TABLE TRAINING_MASTER
ADD CONSTRAINT MyTable_ForeignTableID_fk FOREIGN KEY (
REG_ID
) REFERENCES TESTNEW.TRAINING_MASTER(
REG_ID
)
/

*** Error for " ORA-00942: table or view does not exist "

You should have used GRANT REFERENCES ON TESTNEW.TRAINING_MASTER TO EBMSPTS;
