How to track what your Calc Script/Business Rule is doing?

Question

Hi,
I wanted to know the methods or the best way to keep a track of what your Calculation Script of Business Rule is doing once you execute it.
Or suppose it fails for some reason and the reason is not a syntax error (that it usually would show up in EAS while validating)how can you know what's going wrong?
Please let me know !

All the CDFs are available at - https://www.samplecode.oracle.com/tracker/tracking/linkid/prpl1004/action/ExecuteQuery?query=essbase1
There are also the Echo CDFs in the String collection -
@JechoBoth - Echoes back all arguments passed to the function. To pass an array of arguments use @List(comma delimited list).
@JechoString - Echoes back all arguments passed to the function. To pass an array of arguments use @List(comma delimited list).
@JechoDouble - Echoes back all arguments passed to the function. To pass an array of arguments use @List(comma delimited list).
Saying that they usually need to be a calc block so if you are expecting to find where a calc is up to in an aggregation it is not going to tell you much.
Also you have to watch out if you are calculating a large number of blocks then you can end up outputing more information that you would ever need.
If you look in the essbase application log you can actually get an idea of which part of the script the calc is executing and times without the need for CDFs.
Also if a script fails then the app log is the place to go and check.
You can also look at the standard calc commands in essbase
SET NOTICE - http://download.oracle.com/docs/cd/E17236_01/epm.1112/esb_tech_ref/frameset.htm?set_notice.html
"Monitors the progress of your calculation by providing completion notices at intervals during the calculation. The number of notices depends on the level you specify."
SET MSG - http://download.oracle.com/docs/cd/E17236_01/epm.1112/esb_tech_ref/frameset.htm?set_msg.html
"Sets the level of messaging you want returned about calculations, and enables simulated calculations."
or if on 11.1.2.x then the @RETURN function - http://download.oracle.com/docs/cd/E17236_01/epm.1112/esb_tech_ref/frameset.htm?return.html
"Exits the calculation immediately under specified logical conditions. You can use the IF... ELSEIF calculation command block to specify the logical error conditions, and use the @RETURN function to exit the calculation with customized error messages and levels."
