SQL & PL/SQL :: Query To Find Application Table Column Details Associated With Descriptive Flex Field

I was looking for application column name corresponding to "Draft Invoice Number" ra_interface_lines_all table.

I tried the below.

/* Get descriptive_flexfield_name for the application table name*/
SELECT *
FROM FND_DESCRIPTIVE_FLEXS_VL
WHERE application_id = 222
AND APPLICATION_TABLE_NAME=upper('ra_interface_lines_all');

/* Get the application column name and end user column name*/
SELECT *
FROM FND_DESCR_FLEX_COLUMN_USAGES
WHERE application_id = 222
AND descriptive_flexfield_name = 'RA_INTERFACE_LINES';

There are many DESCRIPTIVE_FLEX_CONTEXT_CODEs obtained. I could finally trace out that draft invoice number corresponds to INTERFACE_LINE_ATTRIBUTE2. How can I know what DESCRIPTIVE_FLEX_CONTEXT_CODE should I look for?

I want to build a single query to fetch the application column name and flex field name for a specific table .
