Retaining a Value in a variable

Hi,
I have a sender query (query 1)and a receiver query(query2). The sender query has a user entry variable C on an info object A(of length 18). The receiver query has a customer exit variable D on an info object B(of length 4).
The customer exit variable D has to derive the last 4 digits of the user input variable C in query 1.
I have linked A and B in the assignment details of the RRI using the variable option.
The problem that i'm facing is that when a jump is performed the variable D has to derive its value from the variable C but when query 2 is triggered by the jump that value in variable C is lost and hence D cannot be populated. Is it possible to retain the value of variable C even after i run the second query so that i can derive D from C.
Help would be highly appreciated

Hi,
why not trying th efollowing:
Assign B as NAV-Attribute to A, containing the last 4 digits of the 18 digits string.
assign B to BOTH queries and use it in the assignment details "generic".
ANother way: assign A to Query2 with variable E, type replacementpath, filled by values out of query 1.
Derive Value for D in step 2 of the var E.
Actually, the first way seems to be easier ... to me ...

Values of same Variable(used in diff reports) shud be retained in a session

Hello,
We have an application cockpit. There are 12 to 13 different reports being used in that cockpit. Most of the reports use the same characteristic variables in the report.
When we used to execute these reports in Ver 3.x, the variables used to retain their values in the same session. i.e. if for 0Material, user gave : 'TIP120' as a value in selection criteria in one report, then, if he executed another report after that, which uses the same variable on 0Material, then it retained its previous value: 'TIP120'.
Recently we have migrated to BW 7.0. Now, the variables no longer retain their values in the same session and the user has to type the value again. (personalization is an option but we want the variable should retain the values in same session).
Any help/advise on this will be of great importance as the user is not very comfortable putting values again, each time he runs the report.
Warm Regards,
Sumita

Doubt : retaining the value between the calls

hi,
Which statement would you use to declare a variable, within a Function Module/Form-routine, so as it will retain the value between the calls?"
Gaurav

Dear Gaurav,
To retain the same value outside a function module, you can define a variable with the same name as the exporting parameter in a function module. However in case of Subroutines you can pass the value by reference as any change in the formal parameters will be reflected in the actual parameters.
Check the following links for further clarification:

In the above program, Can we assign V_num with a value 10????????Yes; the example you posted does that.
When the loop starts, the value 10 is assigned to v_num. You should see that value displayed by the put_line statement.
After that, v_num is set to 10 - 1 = 9.
Next, the EXIT condition is evaluated. At this point, v_num is 9, not 0, so the loop runs again. V_num is set to 10 again, and the loop continues forever (or, in some versions, until the dbms_output buffer is filled and an error occurs.)

Hi Vinayak,
     you will be having your first program values in internal table or some variables,
    when you are calling the second program you wii use like this,
    SUBMIT <Second Program Name> USING SELECTION-SCREEN '1000'
                       WITH s_emp(second program select-options)   IN t_emp(first program variables)

Displaying the value of an variable on the stage

I have managed to display the values contained in string variables on stage, and I am happy with that, however when I wish to display the value of an int and convert it to a string as one is supposed to do the output to the stage just calls it [class int] and does not give its value. any suggestions?
My rogram contains a stage at frame 1 which displays a word. The user must input a word. Frame 30 then displays the word which was displayed and the word input by the user. That all works fine. But the value of the variable NumberRight, which has been assigned to that variable will only display as [class int] without showing its value. (even though I have converet it to a string using the .to string function you see below).
My code is as follows;
trace( "The number correct was" + NumberRight); //This works fine in the output window and shows the value of the variable as NumberRight [class int]1 (showing the value to be 1)
outputText.appendText("in/"+textAtIN); //this works fine displaying the word presented and word input by user as in/in
outputText.appendText( NumberRight.toString(     )); //here lies the problem as it just displays [class int] and nothing else.
Yes I have managed to overcome that problem it was some code on the first frame, please excuse, however, now, is there any way to remove the [class int] bit from the displays, I wish to have the results as a clear copy of the results so that they can be printed out, without [class int] all over the place?

Hi Ned thanks for that. Yes I had accidently created blank spaces in the String() argument. (wanted to check if there was a subsequent difference in display and forgot to return them to normal ...Sorted )
Your next suggestion has eliminated the [class int] but I get a value now of 0.
My code on the first frame for a correct response for example is;
function keyPressedIN(event:KeyboardEvent):void
          if (event.keyCode == 13)/*Normally,this will move straight on to the next frame-
          recording a correct response and all that that implies in terms of scores etc. But now I have re directed it to Frame 30 to check are the variables working properly*/
                    //insert code for correct responses vowels etc.
                    VowelI = VowelI+1;
                    NumberRight = NumberRight +1;
                    stage.focus = stage;
                    //There is no need to display the text box as this is a correct response.
                    pupilsResponseIN.visible = false;
                    mainText.visible = false;
                    gotoAndPlay(30);//at the moment this takes me to the display frame to check if all is ok
On the first frame when the user say hits the Return key my code assigns the value of +1 to the variable; eg
NumberRight=NumberRight+1;
and the value of +1 to the value of VowelI
VowelI=VowelI+1
At Frame 30 the code is as follows;
stop();
trace( "The number correct was"+ NumberRight);
outputText.appendText("in/"+textAtIN);
outputText.appendText( "\n");
outputText.appendText("Vowels Correct ="+(int(VowelI).toString()));
outputText.appendText( "\n");
outputText.appendText("TotalCorrect="+(int(NumberRight).toString()));
//outputText.appendText( VowelI.toString());
Now what I am getting is
in/in
Vowels Correct = O
Total Correct = O
Yet the trace (output box) records the Number correct as [class int]1
many years ago I wrote this same program in Authorware using similar code. I am trying to re write it in FlashCS5 using ActionScript 3 and It take days to solve small problems. I notice also that If for example the user of the program makes an error and I record the error as NumberRight =NumberRight -1 the program records it as Total Correct = NaN .
I gave up on this a few months back but I am trying again. I think there must be a better way to do this. Variables do not seem to add up or subtract for me at present. no doubt its me thats got it wrong.

Default value in recordset variable

Hi,
I am using Dreamweaver 8.
I am not sure that I understand the function of the default
value in the variable area of the recordset. I'm using a search box
and sending the result on through the url. If the person types
something that is not in either of the two fields searched, is the
default value supposed to kick in? I have tried entering a value of
something that is actually in the field, but get a broken image
(x)...I'm displaying images.
What I would actually do is to display an error message on a
different page. Is there a SQL statement that could be put after
the search statement such "if not....go to url or
something"? If not, I was thinking of creating a blank
image with wording stating that there was no match.
Current recordset code:
SELECT*
FROM images
WHERE description LIKE %colname% OR picturenum = colname2
ORDER BY picturenum ASC
Name:colname
Type:Text
Default Value: montana (an actual word in the database)
Run-Time Value: $_GET['description']
Name:colname2
Type:Text
Default Value: A091 (an actual image in the database)
Run-Time Value: $_GET['description']
Current code works perfectly thanks to some direction by
David Powers....thanks David.
Any help would be appreciated.
Thanks,
Cliff

The best way to accomplish this is to build the WHERE clause dynamically, or else have a different WHERE clause that you use in these situations. In other words, test the value of the querystring variables and if they are empty, use a different WHERE clause that does not include the address condition.
Also, this question belongs in the app dev forum.

How to define and populate value to a variable in a text file

hi all,
i have a text file on unix server, when i read it through open dataset, is it possible to populate dynamic value to a variable in the text file. and is it possible to define a variable at any place in the text file?
after this the program will send the internal table for emailing.
thanks.

Hi, If this file on server is a email template you can put some tags / marks and you can change it after you read it with OPEN DATASET / READ...
Sample:
OPEN DATASET p_file FOR INPUT IN TEXT MODE ENCODING DEFAULT.
CHECK sy-subrc EQ 0.
DO.
READ DATASET p_file INTO lv_string.
IF sy-subrc EQ 0.
EXIT.
ENDIF.
REPLACE ALL OCCURENCES OF '((SYSTEM_ID))' WITH sy-sysid.
APPEND input_file_tab.
ENDDO.
CLOSE DATASET p_file.
on file there's a line with:
This email was generated on server ((SYSTEM_ID))
It will be translated to (sy-sysid = DEV):
This email was generated on server DEV
This is a "variable" like that you can use.

Use varialbe as a value in substitution variable

Hi there,I incrementaly update my cube day by day.And I set a user variable in autoexec.bat to get the current date,eg '2003-06-23'.Could I use such variable as a variable's value in substition variable ?My platform is 6.5 on w2k.Regards,luau

You can use that in a MAXL script to set the substitution variable.the MAXL script would be something like:Alter database $4 drop variable $5;alter database $4 add variable $5 $7 ;where: $4 is the app.cub $5 is the substitution variable name $7 is the value of the subs. variableRich Sullivan - Beacon Analytics

Fetches more values into one variable

Hi, inside a cursor loop I'd like to assign, each fetch, a value to a variable, in order, at the end to have a collection of all the values fetched into the same variable.
The code is the following:
CREATE OR REPLACE procedure APPS.AAA as
v_pino varchar2(64);
CURSOR tks_opened_range IS
SELECT incident_number AS YP_TKS_OPENED_WITHIN_RANGE FROM cs.cs_incidents_all_b a, cs_incident_statuses_b b, Cs_Incident_Statuses_Tl c
WHERE b.incident_status_id = c.incident_status_id
AND a.incident_status_id = b.incident_status_id
AND (b.attribute1 <> '3' OR b.attribute1 IS NULL)
AND c.language = 'EL'
AND ((sysdate - to_date(incident_attribute_6, 'dd-mm-yyyy hh24:mi'))*1440) BETWEEN 1 AND 11111111111
AND incident_attribute_2 IN ('ΓΕΝΙΚΗ ΔΙΕΥΘΥΝΣΗ ΤΕΧΝΟΛΟΓΙΑΣ')
ORDER BY incident_number;
rec_tks_opened_range tks_opened_range%ROWTYPE;
begin
FOR rec_tks_opened_range IN tks_opened_range
LOOP
v_pino := rec_tks_opened_range.YP_TKS_OPENED_WITHIN_RANGE;
DBMS_OUTPUT.PUT_LINE('v_pino: ' || v_pino);
end loop;
end AAA;
This works with the variable v_pino!....but at the end, the value of the variable v_pino is ONLY the last fetched by the cursor.
Is there a way to declare a variable (or better a collection) or a new type in order to have all the data fetched into this variable and the end of the fetching ?
I need to know this trick because, after, I have to assign this variable to a pipelined table function.
Thanks in advance

I searched on the note you mentioned in your mail in order to pass an array as a variable to a table function (PIPE ROW call), but I didn't find nothing about it.
Now I explain to you my situation.
I already implemented a table function that works perfectly. I have 2 cursors declared and 2 PIPE ROW calls.

RETURN xxi_statistic_rep_2_1_tab PIPELINED
IS
-- CURSORS FOR THE FIRST SHEET - Tickets opened per group and per duration
-- Cursor for tickets opened within 1 hour --
CURSOR tks_opened_1_h IS
SELECT incident_number AS YP_TKS_OPENED_WITHIN_1_HOUR
FROM cs.cs_incidents_all_b a, cs_incident_statuses_b b, Cs_Incident_Statuses_Tl c
WHERE b.incident_status_id = c.incident_status_id
AND a.incident_status_id = b.incident_status_id
AND (b.attribute1 <> '3' OR b.attribute1 IS NULL)
AND c.language = 'EL'
AND ((sysdate - to_date(incident_attribute_6, 'dd-mm-yyyy hh24:mi'))*1440) < 60
AND incident_attribute_2 IN (SELECT * FROM TABLE(CAST(xxi_szf_discoverer.ypiresia_values(p_ypiresia) AS xxi_ypiresia_list_tab)))
ORDER BY incident_number;
rec_tks_opened_1_h tks_opened_1_h%ROWTYPE;
-- Cursor for tickets opened between 1 hour and 3 hours --
CURSOR tks_opened_1_3_h IS
SELECT incident_number AS YP_TKS_OPENED_BE_1_3_HOURS FROM cs.cs_incidents_all_b a, cs_incident_statuses_b b, Cs_Incident_Statuses_Tl c
WHERE b.incident_status_id = c.incident_status_id
AND a.incident_status_id = b.incident_status_id
AND (b.attribute1 <> '3' OR b.attribute1 IS NULL)
AND c.language = 'EL'
AND ((sysdate - to_date(incident_attribute_6, 'dd-mm-yyyy hh24:mi'))*1440) BETWEEN 60 AND 179
AND incident_attribute_2 IN (SELECT * FROM TABLE(CAST(xxi_szf_discoverer.ypiresia_values(p_ypiresia) AS xxi_ypiresia_list_tab)))
ORDER BY incident_number;
rec_tks_opened_1_3_h tks_opened_1_3_h%ROWTYPE;
PRAGMA AUTONOMOUS_TRANSACTION;
BEGIN
-- FIRST SHEET OPEN CURSORS --
TICKETS NUMBER OPENED WITHIN 1 HOUR
FOR rec_tks_opened_1_h IN tks_opened_1_h
LOOP
PIPE ROW(stat_rep_2_1_type(
rec_tks_opened_1_h.YP_TKS_OPENED_WITHIN_1_HOUR
END LOOP;
-- TICKETS NUMBER OPENED BETWEEN 1 HOUR AND 3 HOURS --
FOR rec_tks_opened_1_3_h IN tks_opened_1_3_h
LOOP
PIPE ROW(stat_rep_2_1_type(
,rec_tks_opened_1_3_h.YP_TKS_OPENED_BE_1_3_HOURS));
END LOOP;
RETURN;
END statistic_report_2_1;
But, in this way and with this syntax, I obtain for each PIPE ROW call only one field filled each time, because I can’t call 2 cursors in a nested loop together (data duplication);
For example:
1st PIPE ROW call : only the first field is filled and into the second I have to put ‘’
2nd PIPE ROW call : only the second field is filled and into the first I have to put ‘’
….and I cant’ call with a single PIPE ROW call two cursor variables…..
Into a Discoverer report this data layout is really bad (you can imagine with thousand
of records).
For this reason I thought to use an array variable (gino) to pass to a single PIPE ROW call outside the cursor loop……but it doesn’t work !!!
Can you suggest me how to resolve this problem….if it possible ?
Did I have to declare other TYPE or collection ?
Thanks you so much

Not able to get the value of ODI Variable when i pass thru Option

Hi,
I have ODI variable called prev_etl_run_date which will hold the last successful etl run date. I want to use the value of this variable in one of my KM step.
But i don’t want to use directly in my KM. So I passed the variable name thru KM Option.
I intend to use the variable’s value in the KM step, as shown below:
<%=odiRef.getOption("MY_OPTION_1")%>
Here I am expecting the value of the variable, but here I am only getting the variable name only.
Is there any substitution method available in ODI KM , please help me to solve this issue.
Thanks
nidhi

ODI options are not intended for run time parameters. They are like design choices or debugging flags or parameters that can be specified in code template. Previous ETL run time stamp is hardly a design choice.
On the other hand, it is really a bad practice to put a variable inside KM directly. That creates a dependency that you can easily avoid by putting a filter using that variable in the interface.
