Solution:

The OKL_TRANSACTION_PVT package was invalid. When this was compiled, the OKL_SECURITIZATION_PVT was invalid. In this way, a number of OKL packages were invalid and the error was cascading. In order to resolve the issue, I logged on to SQL*Plus as sysdba and ran the following commands:

alter package APPS.OKL_TXL_ASSETS_PVT compile;
alter package APPS.OKL_TXL_ASSETS_PVT compile body;
alter package APPS.OKL_TXL_ASSETS_PUB compile;
alter package APPS.OKL_TXL_ASSETS_PUB compile body;
alter package APPS.OKL_SPLIT_ASSET_PVT compile;
alter package APPS.OKL_SPLIT_ASSET_PVT compile body;
alter package APPS.OKL_SECURITIZATION_PVT compile;
alter package APPS.OKL_SECURITIZATION_PVT compile body;
alter package APPS.OKL_TRANSACTION_PVT compile;
alter package APPS.OKL_TRANSACTION_PVT compile body;

OKL_TRANSACTION_PVT now compiles without issue.

To resolve this in future, use adadmin to compile APPS schema. Afterwards, issue the following SQL statement in SQL*Plus to get the number of invalid objects:

select count(*) from dba_objects where status = ‘INVALID’;

Continue compiling APPS schema with adadmin and checking the number of invalid objects until that number no longer decreases.
