Opening Oracle EBS Page from APEX

In this article we shall see how to invoke EBS page from APEX page. Create a link in apex page and mention the URL as below:

http://<<servername>>:port/OA_HTML/RF.jsp?function_id=<functionId>

where

servername -> application server name

port -> EBS port

functionId -> function which you want to invoke.

Below code will help in retrieving host URL:

APEX_UTIL.HOST_URL(NULL)

Any additional parameters to the form function can be passed by appending parameters at the end of the URL.

For ex:

http://<<servername>>:port/OA_HTML/RF.jsp?function_id=XXCUST_ICX_POR_REQMGMT_APPR_HIST&param1=<paramvalue1>&param2=<paramvalue2>

If EBS page has to be opened in new tab/new window add below code in Link Attributes section in APEX page:

target="_blank"

for ex:-

CODE TO GET RATE ADJUSTMENT

In this article we shall see the code to get Rate Adjustment i.e. adjustment resulting from period rate differences between the reporting period and the previous period.

Below code will return the rate adjustment column in “Trial Balance – Translation” report.
