Pass Hierarchy Variable to RSR_OLAP_BADI

Hi Gurus,
I am using RSR_OLAP_BADI. Within the variable selection screen there is a hierarchy selection variable, I would like to pass the variable to the 'compute' badi logic.
What is the best way to do this?
Thanks in advance!.

Hello Tom,
Iu2019m glad that You said youu2019re not struggling with Badi. Let me refresh the memory briefly.
Step 1, Include ZXRSRU01
IF i_s_rkb1d-infocube EQ 'AA'.
IF i_step = '3'.
u2026..
Step 2, Define Method
CASE i_s_rkb1d-infocube.
WHEN u2018AAu2019.
u2026
append l_s_chanm to c_t_chanm
Step 3, Compute Method
u2026
ASSIGN COMPONENT XYZ OF STRUCTURE c_s_data
TO <XYYZZ>.
u2026
Logic for Your Spec
u2026
Jen
PS: Should search for articles about Virtual KF/Char for more details about step 2 and 3.

Hierarchy variable not passed over to universe

Hierarchy variable is not passed to the universe from the query, note 1007048 is not applicable to our system.
Any ideas on what other config to check and change ?

Hi,
- does the query work without any issues in transaction RSRT ?
- do you see the variable as filter in the Universe ?

Input hierarchy variable is not working

Hi,
i have created a BI quary which have a manual input hierarchy variable.Now i have created a Universe on it,and then Qaaws.
In Qaaws this varibale working fine,its gives proper result aCcording to selection of node.Then i have used this in Xcelsius,i have created a connection and then as input value i provided ROOT node key thorugh mapping this to one cell, and mapped the output cell.
Now if when i preview it,its showing no data,and if remove the input node value(balnck cell) then its showing data.I find out that its not taking the value.
What could be wrong here?How to pass hhierarchy node in xcelsius?
Thanks,
Piyush

Hi,
I had the exact same problem. Please have a look at this thread:
xPost: QaaWS, BW, Xcelsius and aggregation
Here is what you need to do (assuming you are on XI 3.1 SP2)
1) Refresh you universe with the option Generate technical names. This will give you an additional detail for each dimension in your universe called ...techname. So if you now check e.g. L01, L02 in your hierarchy they will have this attribute.
2) Create a new web service that includes key and the techname detail
3) Insert this into your visualization and use it to fill e.g. a combo box (key) and return the key + techname when selected
4) You can then use the techname to filter your second web service in the input values

How do I pass a variable from edge animate to an external JS?

I need to pass a variable value from Edge Animate to an external JS file. How can I do it?

Not sure if this is the best way ,but works
Set the variable as a property of a global variable
Like
SET
window.myVar = 'your value';
AdobeEdge.myVar = 'your value';
Read
window.myVar
AdobeEdge.myVar

How do i pass a variable in flex

i've been looking all over google for how to pass a variable yet
i've come up empty handed
i have a C code and as3
i've never been able to get a C program to compile on my own, this is from a tutorial im trying to understand about raycasting
from what i can gather i think that the variables are passed threw this
#######raycaster.c##########
AS3_Val loop( void* self, AS3_Val args )
    AS3_ArrayValue(args,"IntType,IntType,IntType,IntType",&K_UP,&K_DOWN,&K_LEFT,&K_RIGHT);
    CastRay();
    int opos,j,i,jpos;
    for(j=0; j < resY; j++ ){
        jpos = resX*j;
        for(i=0; i < resX; i++ ){
            opos = (jpos+i);
            tBuffer[opos] = buffer[i][j];
        }//end of for
    }//end of for
    return 0;
}//end of loop
however not one of the values inside of AS3_ArrayValue is to be found on the Main.as
this is the only function that comunicates with the C code, but i could be wrong
####Main.as######
        private function enterFrame(event:Event):void {
            alcRCLib.loop(upKey,downKey,leftKey,rightKey);
            alchemyMemory.position=alcScreenBufferPointer;
            screenBitmapData.setPixels(screenBitmapData.rect,alchemyMemory);
the reason i want to do this, other than to know how, because that would be useful above all else, i've already written a as3 that comunicates with php
to get a array of images for a topdown game, and i wouldn't know how to load these variables to C from a HTTP request but if i can get flash to tell c what they are then every thing worked out
heres both codes in full
#####Main.as####

RadioactiveLizard, you need adobe alchemy (http://labs.adobe.com/technologies/alchemy/) to compile the C code to a swc,
not pass variables to C directly.

HIerarchy Variable in Selection Screen not taken into account.

Hi,
Our users choose a cost center hierarchy in the selection screen and run the report. As we have suppressed Unassigned Nodes, they do not appear. However when users then deactivate the hierarchy, unassigned nodes are shown. Their argument is that the unassigned nodes should still not be displayed because a hierarchy was entered on the selection screen. Is there a way of stopping this?
Thanks

Hi Shawn,
I think I get what you did in your query, though it took me some time...
Did you select the cost center in your query and set the display hierarchy using settings, hierarchy tab, select hierarchy, hierarchy variable (or something like that)? That would explain why the query isn't filtered on that hierarchy, only the display of cost elements is affected. You should also have the same hierarchy variable in your filter settings in the query designer. That way, the user filters on a hierarchy and the unassigned nodes will never be in the result.
Hope it helps, tell me if I got it wrong,
Kind regards,
Alex

BW hierarchy variable not working in Crystal Report 2008

Hi,
I have created BEx 7.0 report which has hierarchy on 0customer object, the report is working fine whith hierarchy variable. I have created Crystal Report by using this query as source. I have followed below link to create grouping to get data through hierarchy variable.
http://wiki.sdn.sap.com/wiki/display/BOBJ/BWHierarchiesinCrystalReports
But report does not work for hierarchy variable and report is blank. When I give filter of child node which has actual data then I get report output. For ex.
Below hierarchy for 0customer
11396
- 737007
- 123456
When I run report for 11396 then no data display but when I run 737007 child node I get report output but with blank group name.
Can anyone came accross this issue. Please guide me . Thanks in advance.

Thanks Ingo for your reply..
The word filter means, I have hierarchy node variable in the BEx report that has become Parameter in CR. When I give hierarchy node variable value of parent node then there is not data display but for the child node I get the data.
For ex. In the info cube there is data for 730707 customer but in the customer hierarchy the parent node of 73707 is 11396. I am giving 11396 in the variable pop screen for hierarchy variable. I do not see any data but for 73707 I get data.
User does not know 73707, he always enter 11396 customer no. and he gets data in BEx query that is source of CR. but crystal report is not showing data for 11396.
One more point I want to tell here, I am saving CR at my local system not to SAP BW server.
Hope this clear my issue.

LoadVars-using send to pass a variable from flash to php

For the life of me, I've tried everything:
I've researched LoadVars on Adobe forum, used David Powers'
books, googled 'flash to php', LoadVars, etc. and tried
sendAndLoad, send, and using $_POST, $_GET, $_REQUEST.
$HTTP_POSTVARS but I keep getting this same error. any advice
please?
I have a Unix server running Apache/PHP 4 - LoadVars worked
to load name-value pairs into an array -see thread)
My goal with this simple app is to prototype being able to
pass a variable from flash to a variable in php.
Parse error: syntax error, unexpected T_VARIABLE in
flash_to_SQL.php on line 5
Actionscript 2.0 code:
var c :LoadVars = new LoadVars();
c.testing = "123FOUR";
c.send ("
http://127.0.0.1/flash_to_SQL.php","_self","POST");
php code: (I also tried $_POST, $_GET, $_REQUEST.
$HTTP_POSTVARS)
<?php
//mysql 4.1.2, php 4 , NO mysqli
ecbo $_REQUEST ['testing'];
/?>

var formData:LoadVars = new LoadVars();
formData.fname = "Name";
formData.send("

formData, "POST");

How to pass session variable value with GO URL to override session value

Hi Gurus,
We have below requirement.Please help us at the earliest.
How to pass session variable value with GO URL to override session value. ( It is not working after making changes to authentication xml file session init block creation as explained by oracle (Bug No14372679 : which they claim it is fixed in 1.7 version Ref No :Bug 14372679 : REQUEST VARIABLE NOT OVERRIDING SESSION VARIABLE RUNNING THRU A GO URL )
Please provide step by step solution.No vague answers.
I followed below steps mentioned.
RPD:
****-> Created a session variable called STATUS
-> Create Session Init block called Init_Status with SQL
select 'ACTIVE' from dual;
-> Assigned the session variable STATUS to Init block Init_Status
authenticationschemas.xml:
Added
<RequestVariable source="url" type="informational"
nameInSource="RE_CODE" biVariableName="NQ_SESSION.STATUS"/>
Report
Edit column "Contract Status" and added session variable as
VALUEOF(NQ_SESSION.STATUS)
URL:
http://localhost:9704/analytics/saw.dll?PortalGo&Action=prompt&path=%2Fshared%2FQAV%2FTest_Report_By%20Contract%20Status&RE_CODE='EXPIRED'
Issue:
When I run the URL above with parameter EXPIRED, the report still shows for ACTIVE only. The URL is not making any difference with report.
Report is picking the default value from RPD session variable init query.
could you please let me know if I am missing something.

Hi,

Need a fast answer... passing javascript variable to jsp page (how to use)

This test application has 3 frames.
I'm assigning a value "stuff" to a variable ("testfield1") in a javascript function ("getTest") that exists inside an html frame (testpage1.html)
Then, I click on the "test submit" hypertext link to pass the value of "testfield1" to the JSP frame (testpage2.jsp) by invoking a function ("getData") in "testpage2".
In function ("getData"), I am passing the variable "testfield1" as a parameter to the "getData" function in "testpage2".
In "testpage2" - in the ("getData" function) I try to assign the value of the variable "testfield1" to another variable called "testfld1".
Then, I try to extract the value of "testfld1" into a variable called "tstfld1" in a JSP scriptlet
....I.E. [ String tstfld1 = request.getParameter("testfld1"); ]
But, the value is apparently not passed successfully, as tstfield1 appears to be "null".
Can anyone explain what I'm doing incorrectly?

parent.frames[2].getData(testfield1); is in testpage1.html
so in the document.pageData.testfld1.value = testfield1; document = testpage1.html( not testpage2.html)
modifying the getData to accept the document object, and refering this object to parent.frames[2].document may help you.
good Luck ....

Problem with hierarchy variable while displaying query in Portal

Hi,
I came up with an problem with a query in the portal. The problem is :
I have one query which is displayed in the portal. The Query has hierarchial selection criteria. I am executing the same query using analyzer. Its taking the variable from the selection and displaying it on the analyzer. I have used the option to " display the query on web " from the BEX query designer. From there its opening and displaying the results with the given selection criteria.
Where as when i open the query seperately in portal, its not displaying the results.
I came to know from one of my colleague that the porblem is with the Web item and the hierarchial variable declared in WAD was different from the variable declared in the BEX Query designer.
I never Worked with WAD. I tried finding out the variable definition. But i was unable to find out where the Hierarchial variable was defined.
Please help me out regarding the same.

The problem is sovled.
Poornima.

Passing Session variable of DATE data type to opaque view filter

Hi Everyone,
Can you guys please help me in passing session variable of DATE data type in RPD's physical layer 'opaque view' filter for Oracle database
I tried following syntax, syntax wise I didn't got getting any error, but at the same time this opaque view is not fetching any records as well. my session variable is "END_DATE" and its value is 1998/12/31:00:00:00(as shown in RPD session windows, datatype is DATETIME)
SELECT AMOUNT_SOLD, CHANNEL_ID, CUST_ID, PROD_ID, PROMO_ID, QUANTITY_SOLD, TIME_ID FROM SH.SALES
WHERE TIME_ID =TO_DATE( 'VALUEOF(NQ_SESSION.END_DATE)','MM/DD/YYYY')
SELECT AMOUNT_SOLD, CHANNEL_ID, CUST_ID, PROD_ID, PROMO_ID, QUANTITY_SOLD, TIME_ID FROM SH.SALES
WHERE TIME_ID = TO_DATE( 'VALUEOF(NQ_SESSION."END_DATE")','MM/DD/YYYY')
SELECT AMOUNT_SOLD, CHANNEL_ID, CUST_ID, PROD_ID, PROMO_ID, QUANTITY_SOLD, TIME_ID FROM SH.SALES
WHERE TRUNC(TIME_ID) = TO_DATE( 'VALUEOF(NQ_SESSION."END_DATE")','MM/DD/YYYY')
In past, I was able to pass a session variable into a opaque view filter using DATEOF function, but that was in DB2.
I appreciate your time and help

Finally, I got right format. here it is
to_date(substr('valueof(NQ_SESSION.END_DATE)',1,10), 'yyyy-mm-dd')
and here is the source from where I got this information
