SQL & PL/SQL :: Receiving ORA-29913 And ORA-30653 Errors And Query Does Not Complete

Receiving ORA-29913 and ORA-30653 errors and query does not complete. The queries that receive the error are shown below <> represents substitute your filename; There are actually three different queries that must run to produce an expected output. Those queries run in the order which they appear below:

Query1
select distinct HLQ "highlevel", RESOURCE "RES" from <filename1>

Query2
select distinct ENT.RESOURCE "RES", ENT.ID "PLEX"'
case
when ENT.ACTION is null then nextkey'
else ent.action
end "ACT",
case
when ENT.ACTION is null then ENT.CONDITION_NEXTKEY
end "NRULE",
'TESTSET' "ENTTYPE", replace(My.Owner, '"',' ') "Owner"
from <filename1> ENT, <filename2> ORS
where ENT.f1 = ORS.f2
and ENT.APPLICATION = '<entertypehere>'

Query3
select ENT.ID "AID", ENT.RESOURCE "RES", ENT.ID "PLEX", replace(My.Owner, '"',' ') "Owner", TESTSET' "ENTTYPE" from <filename1> ENT, <filename2> ORS
where APPLICATION = '<entertype>'
and ENT.<f1_column_name> = ORS.<f2_column_name>

Error returned is: "Ora-29913: error in executing ODICEXTTABLEFETCH callout; Ora-30653: reject limit reached"

In the log file of the job that runs these queries, I can also see the following

NULL if (CAS9 = ~) error processing column C5 in row 1 for datafile /home/oracle/DataDir/<filename>_metadata.data

I have checked and it looks like the routine creates ODICEXTTABLEFETCH as it needs it and then throws it away leaving me with Ora-12899 Value too large for column C5 (actual: 13, maximum: 10)
