When you work with EBS software you are bound to come across concurrent programs and concurrent requests.
Concurrent requests are administered in the table "FND_CONCURRENT_REQUESTS". This table contains columns named "OFILE_SIZE" and "OUTFILE_NAME". Digging deeper into these entries, you will soon realise that "OUTFILE_NAME" not always references the requests end result. This has to do with the OPP for which I may some day do an other post.
Bottom line is that the actual end result is stored in a different table: "FND_CONC_REQ_OUTPUTS".
APPS@EBS>desc FND_CONC_REQ_OUTPUTS
Name Null? Type
--------------------- -------- -------------
CONCURRENT_REQUEST_ID NOT NULL NUMBER
OUTPUT_ID NOT NULL NUMBER
FILE_TYPE NOT NULL VARCHAR2(30)
FILE_NAME NOT NULL VARCHAR2(255)
FILE_NODE_NAME NOT NULL VARCHAR2(255)
FILE_SIZE NUMBER
ACTION_TYPE NUMBER
FILE_CREATION_DATE NOT NULL DATE
Ofcourse the CONCURRENT_REQUEST_ID is a reference to the base table. Bonus loot; you get the "FILE_TYPE" too!
