WRITEQUERY to be excuted in program and filling Variable values

Hi SDN Community,
Is it possible to execute the WRITEQUERY FM, within ABAP,
And at the same time have the variables in the query populated.  ie.  do not force the variable screen to popup and fill it in.
Can you please provide a simple example if this is possible.
Thank you.
Simon

Thank You Praveen.
These look very useful, i will shortly be testing them.
You may be able to answer the following questions:
1) The output of those BLOGS is XML.  would it be possible to simply put the contents in a table directly.
Do you think it would also be possible to do the following:
1) Create a function module that calls ZWRITEQUERY
(ZWRITEQUERY is a copy of the original code)
If we could then pass the genuid to this code via the input paramater to be set up in our FM.
to uncomment any code that displays the variable screen.
To then allow the code to execute
I would also like to try to find the code where there variables can be passed.
But then i think the above is quite complicated.
Thank you.
Simon

  • Query property "Save and reuse variable value" doesn't work in BW EHP1

    We have a workbook which contain 4 queries, every different worksheet is a different query.
    All the queries are on the Same InfoCube and all the queries use the same variables.
    In the properties of the query n.2 we set the parameter "Save and reuse variable values" then we refresh the 1st query and all work fine (the system asks the variable values) but when we refresh the 2nd query the system doesn't use the same variable values that we have inserted for the query n.1
    We don't have the same problem in 7.0.
    Any help is appreciated.
    Luca

    Hi,
    I suppose, you need to set the 'Save and reuse variable values' for each query individually in the workbook. I am not sure however there is a option where you can specify to apply the settings of one query to all queries in the work book.
    Please check and hope it helps.

  • ABAP program and FB for value mapping replication

    Hi,
    we are using a 40B system and I want to use the value mapping replication in XI. To refill the data into the XI database I must write an ABAP and a function module to transfer the data out of R/3 into XI (via RFC). Has anybody an example how the program (and the FB) must look like? i.e I want to read table mvke and extract the materialnumber and the prodhierarchy.
    Thanks and best regards
    Arnold

    Hi Arnold,
    First you need a table type with a structure like follows:
    operation
    groupid
    context
    identifier
    agency
    scheme
    (corresponding to the Interface ValueMappingReplication)
    All used data elements should have type string or charXX
    for example: operation - char10, groupid - char32, rest - char120
    Next you create a function module with attribute 'remote-enabled module'.
    The import parameter is your new table structure.
    Next you create an ABAP program. Here an example:
    report z_value_mapping .
    tables mvke.
    data:
    p_value_mapping type zvalue_mapping,
    p_value_mapping_table type zvalue_mapping_table.
    p_value_mapping-operation = 'Insert'.
    p_value_mapping-context = 'http://xi.com/Material'.
    select * from mvke where matnr between '170' and '501'.
    check not mvke-prodh is initial.
    * Create a value mapping group to join two entries.
    * use a unique 32 digit number.
    concatenate '00000000000000' mvke-prodh into p_value_mapping-groupid.
    translate p_value_mapping-groupid using ' 0'.
    * Store the mapping source as first entry to the group
    p_value_mapping-identifier = mvke-matnr.
    p_value_mapping-agency = 'SenderAgency'.
    p_value_mapping-scheme = 'MATNR'.
    append p_value_mapping to p_value_mapping_table.
    * Store the mapping target as second entry to the group
    p_value_mapping-identifier = mvke-prodh.
    p_value_mapping-agency = 'ReceiverAgency'.
    p_value_mapping-scheme = 'PRODH'.
    append p_value_mapping to p_value_mapping_table.
    endselect.
    * Push data to XI
    call function 'Z_VALUE_MAPPING' in background task
      destination 'IS_XID'
      exporting
        value_mapping       = p_value_mapping_table.
        commit work.
    Import the RFC to the Integration Builder, create a mapping between your RFC and the interface ValueMappingReplication.
    Check this Blog for additional steps:
    /people/sreekanth.babu2/blog/2005/02/23/value-mapping-replication
    Choose names for context, agency and scheme which are useful your scenario.

    Hi Shai,
    the webservice is working well, trying to test it with webservice navigator.
    He also returns the correct number of rows (because there appears slider beneath the table output and I also counted the rows), but there is no data displayed in visual composer.
    I have got no further ideas, what the problem is...
    THank you for your support.

  • Creating Poplist and filling up values in it dynamically.

    Hi,
    I have created a poplist based on a viewObject.It works fine.
    Is it possible to populate values into poplist at runtime.
    ie ..I have a String array and I want to show it in the poplist.
    String[] names = {"ABC","XYZ","PQR"};
    Is it possible to create a poplist to show these values programmetically?
    In a JSP I would do like this..
    <SELECT>
    <%
    for(int i=0;i<names.length;i++)
    {%>
    <OPTION><%=names[i] %>
    <%

    Hi Tapashray,
    Thanks for the reply.
    I have few doubts on your answers.As I am new to OA, my questions might look silly.I have written my interpretation.Please validate and give me some hint to solve it.Thanks :)
    1.Create a VO at designtime.
    - VO must not be based on any EO but should be SQL based and as the data is not picked from Database, what "query" need to be written for the query section in the wizard?
    2.populate the VO attributes with values from your array at runtime
    - The values will be poplulated into VO and poplist simultaneously(dynamically) at runtime OR VO will be populated in prior and at runtime only poplist will be loaded?
    - How to populate values into VO?
    3.remember to use Picklist View Instance property
    - Do i need to specify the View Object Name here? ex:"NamesVO"
    thanks,

  • Customer Exit - Fill variable value - Report is showing wrong records

    Hi Gurus,
    I'm building a query where the user will type a date.
    So I need to show in report just the records where Valid From <= User input date <= Valid To.
    I've created to variables for this:
    ZMSCOG07 (Single, Mandatory) = user input variable used in Valid From characteristic restriction.
    ZMPCOG10 (Single, Mandatory) = customer exit variable to get ZMSCOG07 value and to be used as restriction to Valid To characteristic.
    Then in the query I restricted Valid From characteristic:
    Valid From <= ZMSCOG07
    and Valid To characteristic:
    Valid To >= ZMPCOG10
    Follow my code in CMOD transaction:
    WHEN 'ZMPCOG10'.
        IF I_STEP = 2.
            READ TABLE I_T_VAR_RANGE INTO LOC_VAR_RANGE
            with key VNAM = 'ZMSCOG07'.
            CLEAR L_S_RANGE.
            if sy-subrc = 0.
                L_S_RANGE-LOW = LOC_VAR_RANGE-LOW.
            endif.
            L_S_RANGE-SIGN     = 'I'.
            L_S_RANGE-OPT      = 'EQ'.
            APPEND L_S_RANGE TO E_T_RANGE.
        ENDIF.
    I already tried to put L_S_RANGE-OPT = 'GE' in the variable range and in the query to restrict Valid To characteristic:
    Valid From = ZMPCOG10.
    But it's not working correctly. The report is just considering Valid From restriction and showing to me all the records where Valid From <= ZMSCOG07. It seems that ZMPCOG10 is not being filled. Could somebody help me?
    Thanks in advance,
    Helder

    Hi Helder,
    I understand your requirement but I don't understand the solution you are using. I think it's a bit tricky.
    What I would do is:
    Create three variables:
    - VAR1: Single value, mandatory, ready for input, customer exit. Used to store "User input date"
    - VAR2: Select option, customer exit, not ready for input. Used to store Valid From restriction.
    - VAR3: Select option, customer exit, not ready for input. Used to store Valid to restriction.
    Then, use this code:
    WHEN 'VAR2'.
    IF I_STEP = 2.
    READ TABLE I_T_VAR_RANGE INTO LOC_VAR_RANGE
    with key VNAM = 'VAR1'.
    CLEAR L_S_RANGE.
    L_S_RANGE-LOW = LOC_VAR_RANGE-LOW.
    L_S_RANGE-SIGN = 'I'.
    L_S_RANGE-OPT = 'LE'.
    APPEND L_S_RANGE TO E_T_RANGE.
    ENDIF.
    WHEN 'VAR3'.
    IF I_STEP = 2.
    READ TABLE I_T_VAR_RANGE INTO LOC_VAR_RANGE
    with key VNAM = 'VAR1'.
    CLEAR L_S_RANGE.
    L_S_RANGE-LOW = LOC_VAR_RANGE-LOW.
    L_S_RANGE-SIGN = 'I'.
    L_S_RANGE-OPT = 'GE'.
    APPEND L_S_RANGE TO E_T_RANGE.
    ENDIF.
    I think this should work, and you'll have three independent variables used for one purpose each.
    Hope this helps.

  • Program to populate variable values in BPS thru file

    Hi All,
    I've layouts in BPS. In my layout my super user has to change Version/ Actual period/forecast period/previous version everymonth. For all the above we are using varibles.

  • Direct database request and session variable value

    Hi,
    I have a problem by doing the following : idea is to have report with a list of all tables in user schema (which are not all in repository physical layer).
    By clicking on the name of any, should bring answer report which is done as direct database request doing basically select * from table_clicked (this will be basically the same table with sufix _err holding error rows).
    What I'm trying to do is having some kind report for error rows which can be in different tables in my database. So i had in mind to construct name of table i need , and pass it to database request through session variable. Am i doing right by doing direct database request like this :
    select * from 'VALUEOF(NQ_SESSION.TestVar2)'
    Is there another easyer way of doing this? I know this can be done by gourl by passing parameters but not sure how when i can't filter columns in direct database request (this can be different tables with different names of columns). I hope i didn't complicated this too much.
    Thnx in adwance

    Hi,
    I know this is a hack, and would be much more easy to create one table with dimension and measures, but this is intended to be used with code generator, which can produce different error tables with different column names in different time: It is not conviniet for somebody to add them to repository every 5 minutes. For example : i run my workflow and for first run I have errors in table1(let us say customer table with 30 columns) and if click on the table name in some answer report, i want to see all the bad records in the table. Tomorrow after the run, there are bad records in table1 and in table2 (lets say products) so I would have choice to pick table 1 or table2 and see al the bad records in any of these tables. This means that I can not now which tables will I have tomorrow, and as it is generic, I can manually add some tables in my model, and would have to add err table also as a possibility to have error rows?
    I saw post saying that you can pass parameter value by using go url functionality, by modifying configinstance file, but didn't suceed - http://gerardnico.com/wiki/dat/obiee/logical_sql/obiee_session_variable_go_url . Maybe some mistake or any better solution? I created session variable TestVar2, also modified instanceconfig.xml by adding this before </ServerInstance>
    <ParamList>
    <Param name="NQ_SESSION.TestVar2" source="url" nameInSource="SETVAR"/>
    </ParamList>
    and used go url in column formula : ''||"Physical Targets"."Physical Table"||''
    Can I use @1 for using first column value?
    Thnx

    hi all,
    thanx a lot for your help,specially hari52
    hari52 strangely enough the code started working,but
    now i have another problem
    after a while my server hangs or gets shutdown ,a
    message is shown as
    "java.exe has generated error and will be shutdown"
    i know that more connections can be a prob. but i
    make sure that connections r closed on each page,also
    i am a newbie and do not have the time at present to
    learn abt. connection pool ,can this problem be
    solved easily?
    it would be a great help again on your part,
    thanx again,You remove the System.exit(1) line from the code inside the catch block
    and try again. That's the reason tomcat getting down. System.exit(1) should not be used inside jsp. it will make the underlaying Servlet Engine to shutdown.

  • How Can I Dynamically Name and Set Variable Values?

    First one with a correct answer will have the FUNCTION named after them......
    What I want to do is create 'new' variables based on the index of the parent.
    So, if I have 4 subforms called 'Panel' (Panel[0], Panel[1], Panel[2], Panel[3]), I want do declare a local variable in my function to count from 0 to n  for each Panel.
    We won't know how many Panels we will have until runtime. So, I need the variables to keep track of the count (it's tracking the number of errors) - for each Panel.
    Something like this:
     if(obj.rawValue==null || obj.rawValue=="")
    var errorCount[obj.parent.parent.index]=errorCount[obj.parent.parent.index]+1;
    app.alert(errorCount[obj.parent.parent.index]);
    I am assuming it has something to do with Arrays.  But I suck at Arrays.
    Thanks for the help.

    You're correct, arrays are the way to go.  Define your error array like this:
    var errorCounts = [];
    Then, understand that when an array entry is not set it will have the value 'undefined', so you can know if an entry has been initialized.  So to increment the count for a particular index (subform occurance) use:
    // If entry is being set for the first time, set it to 1.  Otherwise increment count.
    if ( errorCounts[index] == 'undefined' )
        errorCounts[index] = 1;
    else
         errorCounts[index]++;
    You can also loop through and initialize the array to zero; then you can remove the check for undefined.  How and where you do this and how you figure out what 'index' is depends on how your form is set up and which event you're using to kick off the error check.  Give me a little more detail on what you're trying to do.

  • Datasocket and Shared Variables

    I am curious if there is any advantage to using Datasocket to read/write shared variables (as opposed to a direct read/write).  I'm specifically talking networked shared variables here.
    Is there any speed advantage to accessing shared variables thru the Datasocket functions?  Since both a direct read/write and a Datasocket PSP read/write talk to the same variable engine I assume they are equally efficient but I'm looking for confirmation here.  I've seen benchmarks for shared variable performance but none of them use DS/PSP to access the variables.
    Normally I would not even think of using Datasocket to access shared var's but where I currently work we have a large app that does this and it works great.  I suspect that this functionality only exists in LV8.x for backward compatibility and non-Windows OS compatibility and is not really meant to be used for new, Windows-based apps?   Am I off base on this?
    I am working in LV 8.5, BTW.....

    Hello Jared,
    Thank you for the reply with clarification. 
    Based on your comment, I changed the buffer parameters and also tried the programs with two different data types, previously StringArray and now String.
    In the attached LV8.6 project, you have all the programs, and shared variable library to review my tests. 
    There are two sets of two files - each set has a Write Shared Variable and Read Shared Variable file. One set is for StringArray type Shared Variable (named StrArr in the library), and the other set is for String type Shared Variable (named Str in the library).
    String Array example:
    MultipleDS-Write-SharedV-StrArr.vi / MultipleDS-Read-SharedV-StrArr.vi
    In my String Array shared variable, I use only 4 element array, each having 4 character strings - meaning 16 bytes per String Array data. I have two loops in the write file, writing to the same variable, an array of 4 strings, each loop continues until the loop index is >0. This means, sometimes, depending on the processor speed, the variable will be written 3 times or 4 times (the variable could have a new value before the loop condition is checked).
    So this means, if I have buffer of 100 bytes (16*4=64<100), it's enough for 4 such arrays (of 4 elements, each element with 4 characters) could be buffered to have sufficient time at the client (Read) program to read them. 
    I am putting 2048 bytes in buffer, which is much more than sufficient in my case. 
    The writer loops run with 200 ms to wait for each iteration. The reader loop runs with 100 ms in DS timeout and 100 ms in wait timer. This gives results without any loss. However, if I run the reader loop with 1000 ms to wait for each iteration, the data is lost. The buffer is not maintained for 2048 bytes.
    In the read program, just to make sure if all data is read or not, I am showing data in two different string indicators, showing data of each loop.
    String example:
    MultipleDS-Write-SharedV-Str.vi / MultipleDS-Read-SharedV-Str.vi 
    The String Array shared variable didn't show values in the Distributed System Manager. Hence, I created another simple variable with String datatype.
    The writer program writes strings of 4 characters, one-by-one, in two loops. Meaning, total 8 strings of 4 characters each are written in the "Str" Shared variable. 
    The reader program, however, doesn't always display all the 8 strings. Although the wait timer is not high (slow) it still misses some data usually. Data is overwritten even before the buffer is filled (in buffer, I have defined 50 strings with 4 elements in each).
    In both of the Read programs, I read using datasocket. I think thought datasocket has more ability to buffer. Earlier I had "BufferedRead" in DataSocket, which I have changed to just Read, because BufferedRead didn't give any special buffer advantage in the Shared Variable reading.
    ---- This is an update on the issue. 
    Ok, just while typing the last paragraph above, regarding datasocket, something clicked in my mind, and I changed the DataSocket functions to simple Shared variables (completely eliminating datasocket functions) in the read programs as well. And bingo, the buffer works as expected, even if I have reading loops very very slow, there is no data loss in any of the program sets. 
    The two changed Read programs are also included in the attached project - MultipleSV-Read-SharedV-Str.vi and MultipleSV-Read-SharedV-StrArr.vi
    So this means, I can completely eliminate DataSockets (not even using PSP URLs in DataSocket Open/Read functions) from my programs. 
    One question here, what will be an advantage of this (or any side effects that I should be keeping in mind)?

  • FixValues and Global Variable

    hi,
    Is there a functionality which does exactly like FixValues but stores the value thorugh out the mapping?
    I have a requirement where i have to map 2 different values to other values but i have to repeat this for all the fields using FixValue instead if there would be a Global Variable i could use that instead.
    Any ideas.
    Thanks,
    KP

    Hi Tirumal,
    For your requirement you can define a HashMap in Java Sections Tab of Graphical mapping and refer the values from UDF.
    Steps
    1. Goto MessageMapping (Design TAB)-> Edit JAVA Sections (Found on top-right side)
    2. Declare a HashMap in Global variables section.
        Eg.
    HashMap materialNumMap = null;
    3. Initialize the same variable and fill some values.
        Eg.
    materialNumMap = new HashMap();
                materialNumMap.put("MAT-01","10001");
                materialNumMap.put("MAT-02","10002"); 
                materialNumMap.put("MAT-03","10003");
                materialNumMap.put("MAT-04","10004");
    4. Write UDF to retrieve value from Global container
    public void chkExists(String materialNUM,ResultList result,Container container){
      String valueFrmMap = (String)materialNumMap.get(materialNUM);
      return valueFrmMap;
    Hope this solves your problem.
    Regards,

  • Business parameter and project variables

    I want to know if Business parameter can be used in place of a prpject variable. My understanding is project variables require an alter command on the DB script during deployment and it is limited to 150 for 1 engine. Hence we dont want to use them. Also wanted to know where are business variables stored in the DB schema. Is there any place where we can get the Engine DB and Directory DB model with relationships and attribute details so that I can understand the system better

    I should have been clearer. A business parameter is not used to store information about a specific instance flowing through the life of a process. They are used as "constants" (quotes around this are explained in my thread above) that can be changed by business owners. They are different than project and instance variables in that:
    1) Business Parameters are global - this means that their value is the same for all processes running on the Engine (e.g. if MIN_CREDIT_SCORE is set to 650 by a business owner, then all instances in all processes that use this know it's value is 650). Both project and instance variable values are unique to each individual work item instance running on a specific process on an Engine.
    2) Business Parameters are infrequently changed and if a business owner changes them to another value, all instances running on the Engine will see the new value.
    3) The global value of business parameters are stored in the Directory Service database. Project and instance variables are stored in the Engine's database.
    4) Business Parameters are not something that you would want to run a BAM report on since their values are global and not specific to a particular work item instance. Again, it's better to think of them as constants. They're not going to help you with BAM reporting.
    Hope this helps,
    Dan

    Hi! I have a Creative suite Design Standard 9 Adobe program and I am attempting to make a wizzard form that can be made into an entry form for a competition. So I need to 1. Make the form into a question and answer form that Participants may fill out. 2. make it possible for them to download it via a link on our website 3. make it possible for them to save the info they have written into the form and mail it to the mail we have supplied in the entry form and 4. make it possible for them to put in a jpg. as part of the entry for and lastly 5. make it possible for us to copy paste the document and use it on other platforms. How do I do this - is it at all possible with adobe?

    Those requirements are go way beyond what PDF forms can do and are meant for, some of them would require involving other programs or are mutually exclusive and contradictory. You are wasting your time even thinking about doing this as an "offline" PDF form. Simply sign up for an online forms/ survey service like FormsCentral or Surveymonkey.
