How to Access DB2 MQT (Materialized Query Table) in Crystal 10

DB2 V8 has a new construct called a Materialized Query Table (MQT) that is essentially a table containing the data represented by a view. This MQT does not appear in the Database List in Crystal under Table, View or Synonym. I assume it is due to the Database Type in DB2 (M). How can I make Crystal recognize the MQT so I can use it in a report?

Hi Linda,
This question was posted internally and OLE dB is the work around but no version of CR was noted so not sure if this will work for you. If it doesn't work in CR 10 then you'll have to upgrade to a more current version.
Because MQT is new to DB2 Crystal 10 OLE dB driver may not know how to handle them.
Thank you
Don

Selecting from Materialized Query Tables (DB2 UDB database)

When selecting what objects I wish to view in my Reports, I am unable to see any Materialized Query Tables in the list. I am able to see the "normal" Tables and Views, just not any Materilized Query Tables.
Please let me know what I need to set or customize in-order to see and then select fields from these.

Thanks everyone.
I was able to find the answer.
For the new report, in the "Create New Connections"...choose "OLE DB (ADO)" --> then "Microsoft OLE DB Providers for ODBC Drivers" --> click on the "Next" button --> choose the database --> then user/password details (..and so forth).

How to access hidden fields in a table

hi
what is the use of hidden fields in a table, ie. some fields doesn't visible in the field list of a table. but the fileds will be visible if u display its contents.
for example in table t518A the text field is not visible in the field list. But it will be visible if display its contents. can any one of u please help me out how to access those fields.
regards
sri

Hi Srivallika,
The table T518A has a text table called T518B. You can have a look at this table by:-
1. GOTO SE11 and display table T518A.
2. GOTO menu GOTO -> TEXT table. It gives the text table for the given table. Here its is T518B.
A Text table is table with same key fields as the main table with another extra Language key TYPE SPRAS. This table is related to the main table. Hence to access the extra text fields, you can use the TEXT table :).
Thanks and regards,
Ravi.

How to access information in R/3 tables

Hi!
I have a long chain of 3 tables in R/3 to finally receive a link from a function module, that gives me Track and Trace functionality.
Now, the final function module is made and working.
But how do I (from inside Visual Composer) get access to various tables in R/3.
The tables in question are:
1) VBFA
2) VEPO
3) VEKP
which can all be found from SE16 in R/3.
I figure I somehow need an ABAP-developer, but maybe - just maybe - there is an easier way running a RFC or web-enable a table for input etc.?
What do you advise I do. I can retrieve all the necessary from within R/3, but the end-user will have to run it via a porta-interface within a Visual Composer Model that I am trying to get hold of.
ANY suggestions are appreciated.
Best regards
Jakob Diness

Jakob,
You may want to try the BAPI Explorer (BAPI) for finding what RFC's are available. You can drill down by functionality area or look for an object alphabetically. For example I looked alphabetically and found HandlingUnit, which is what a couple of your tables appear to pertain to. You can then test those functions under Handling Unit to see if any provide what you need.
I hope that is helpful.

How to access changes made in a table?

Hi Brothers,
I have a table showing information that was read from the backend. The user is able to make changes to cells in the table. access the now, I need to access the changes made by the user for processing.Unfortunately, I do not know how to that...
Do I have to create an Object containing the changed table? Do the chnages take effect in the actual Context node so that I just have to use this?
Thanks, Johannes

I solved it completely,
here the coding for version 7.1:
public void onActionValidateChangesCustomer(com.sap.tc.webdynpro.progmodel.api.IWDCustomEvent wdEvent )

How to access FlashVars or URL Query String

I am a bit of a rookie with Flash/AS3 and I need help trying to access FlashVars or URL in Object/Embed tags. I've searched in the Internet and the forums but cannot get my head around how to implement this. Here is my example.
1) ACTION SCRIPT - I have created a simple flash banner with clickable button (sparkle) with a mouse down event.
The action script (AS3) for the button is the following:
sparkle.addEventListener(
    MouseEvent.MOUSE_DOWN,
    function(evt:MouseEvent):void {
        var url:String = "http://www.[site_url].com/as/img.cfm";
      var request:URLRequest = new URLRequest(url);
        var variables:URLVariables = new URLVariables();
        variables.gphc = "382";
        request.data = variables;
        request.method = URLRequestMethod.GET;
      navigateToURL(request);
     *** the core issue to resolve is how to make the line above (variables.gphc = "382";) to be set dynamically. I would like for the variable to come from the FlashVars or the URL vars
2) OBJECT/EMBED - my object/embed code with include FlashVars and URL Query String
<OBJECT classid="clsid:D27CDB6E-AE6D-11cf-96B8-444553540000" codebase="http://download.macromedia.com/pub/shockwave/cabs/flash/swflash.cab#version=6,0,40,0" ID="bannerAD" WIDTH="728" HEIGHT="90">
     <PARAM NAME="movie" VALUE="http://www.[site_url].com/images/imgs/flash_ad.swf?gphc=382">
    <PARAM NAME="quality" VALUE="high">
    <PARAM NAME="bgcolor" VALUE="#FFFFFF">
    <PARAM NAME="FlashVars" value="gphc=382" />
    <EMBED src="http://www.[site_url].com/images/imgs/flash_ad.swf?gphc=382" quality="high"WIDTH="728" HEIGHT="90" TYPE="application/x-shockwave-flash" PLUGINSPAGE="http://www.macromedia.com/shockwave/download/index.cgi?P1_Prod_Version=ShockwaveFlash" FlashVars="gphc=382" />
</OBJECT>
Questions that I need answered ... How do we access the FlashVars or the URL Query String? I have found many references to loaderInfo but no clear way to implement that I'm able to understand. So if the loaderInfo is the key, where do I add in the loaderComplete() function into my action script above in #1?
function loaderComplete(myEvent:Event)
var flashVars=this.loaderInfo.parameters;
gphcTextField.text=flashVars.gphc
this.loaderInfo.addEventListener(Event.COMPLETE, loaderComplete);
Any help is much appreciated.

Thank you for your input. I implemented your sugguestion in the following way without any success. Notice below in the addEventListner that I have added the snippet of code. Is this a good place (correct place) to set the local_var? I did confirm that the FlashVars and URL variables were set.
sparkle.addEventListener(
     MouseEvent.MOUSE_DOWN,
     function(evt:MouseEvent):void {
         var url:String = "http://www.[site_url].com/as/img.cfm";
         var request:URLRequest = new URLRequest(url);
         var variables:URLVariables = new URLVariables();
         var local_gphc:String = LoaderInfo(this.root.loaderInfo).parameters.gphc;
         variables.gphc = local_gphc;
         request.data = variables;
         request.method = URLRequestMethod.GET;
       navigateToURL(request);
Thank you for your help.

How to access ( DML) not a source table?

I'm very confused with the error message, since i 3-ple check the table. and the "delete" process on the *source* table works fine.
Please help.
I also found Andy's post suggesting to create an PL/SQL routine and call it by "on submit" event.
http://forums.oracle.com/forums/thread.jspa?threadID=825248&start=15&tstart=0
Just curious if it's possible to make this action using standard form wo going with Andy's suggestion.
Please advise.
Andrew

Andy, thank you.
It works now.
A quick ( hopefully ) follow up question :
once i inserted the row, i want to remove that row from the source table.
right now i have unconditional process , but it's failing.

40     reset page     Clear Cache for all Items on Pages (PageID,PageID,PageID)     Conditional
I'm implying that the "delete" should only occur if "insert" was successful ...
..And, to make life interesting, i have a button "Delete" that invokes the delete process to explicitly remove the row from the source table.
thank you

How to use function module together with tables in Crystal Report?

Dear all expert,
I have the following situation where I need to use a function module in my crystal report, But how can I link the FM with the tables so that I can pass out some value from the FM to the report?
Thank You.

Hi,
Hope the following helps..
1)
LOOP AT IT_OUTPUT.
Call the function module to get the tracking number and store the output in the
variable V_TRACKINGNO.
IT_OUTPUT-TRACKING_NO = V_TRACKINGNO.
MODIFY IT_OUTPUT TRANSPORTING TRACKING_NO.
ENDLOOP.
2) Date conversion
DATA: V_CHAR(10) VALUE '2006.11.17'.
DATA: V_DATE TYPE SYDATUM.
CONCATENATE V_CHAR(4) V_CHAR5(2) V_CHAR8(2) INTO V_DATE.
WRITE: V_DATE TO V_CHAR MM/DD/YYYY.
WRITE: / 'MM/DD/YYY Format - ', V_CHAR.
Please make sure to reward points for helpful answers..

How to access single column in table?

Hi,everybody!
How to access a single column in table.
I sorted my table with standard TableSorter.
Now I need to get one column from this table to
do something with it's data.How do I get it?
Regards,
Michael

Hi Michael,
If you just want to retrieve the data, you could use the following code.
//Get the node which the table is bound to
IWDNode node = wdContext.nodeTable();
//iterate thru the elements
for(int i = 0 ; i<node.size();i++)
IWDNodeElement ne = node.getElementAt(i);
Object value = ne.getAttributeValue("<column name>");
//Here you have the data in the value variable
//and you can manipulate this now

Power Query; How do I reference a Power Pivot table from a Power Query query

Hi,
It's pretty awesome how you can define Extract Transform and Load processes within Power Query without having to type in a single line of code. However how do I reference a Power Pivot table from a Power Query query to avoid me repeatedly accessing
the same data source (CSV) file with a view to increasing performance?
We are aware of the reference sub menu option with Power Query. However the new query created by the "reference" option still seems to refresh data from the data source (CSV) rather than just referencing the base query. Is this understanding
correct? There does seem to be a lot of hard disk activity when re-running the new query which is based on a base query rather than a data source. So we were hoping the new query would just need to reference the base query in memory rather than rescanning
the hard disk. Is there any way to ensure that the reference query just rescans the base query in memory?
Kind Regards,
Kieran.
Kieran Patrick Wood http://www.innovativebusinessintelligence.com http://uk.linkedin.com/in/kieranpatrickwood http://kieranwood.wordpress.com/

Hi Kieran,
This sounds like something to be suggested for a future release. At the present time, Power Query will always re-run the entire Power Query query when refreshed. The Reference feature is analogous to a SQL view whereby the underlying query is always re-executed
when it's queried, or in this case refreshed. Even something like using the Power Query cache to minimise the amount of data re-read from the disk would be helpful for performance but the cache is only used for the preview data and stored locally.
It would be a good idea to suggest this feature to the Power BI team via the feedback smiley face.

How to access tables/views of an external database provider..

After much trouble I finally managed to setup a second Database Provider that doesn't display the "0 out of 0 connections are good" error by filling in the "Configuration Class" field with "intradoc.server.DbProviderConfig".
But now the problem is actually accessing the tables/views in my newly configured external database provider...
In the Configuration Manager applet when I try to add a new Table or View it only lists the tables contained in the schema of the SystemDatabase database provider (the original one), I've tried running Queries via components trying stuff like SELECT * FROM provider_name.table_name and other similar but obviously it doesn't work...
So... with that said, I just want to know how I access tables or views in my "supposedly" well conected (15 out of 15 connections are good, no errors on the Test Query) Oracle external Database Provider - After searching I was unable to find any information regading any post-provider-setup actions in the Content Server documentation - Does anyone know how to do this?
On a side note, if the database is SQLServer instead of Oracle, with the same configuration and apparently no errors on the database side (other clients access it well) the Query Test of the new database provider returns the following error:
"The provider 'TestSqlSrv' is in error. Unable to create database connection for JDBC:ODBC:SqlSrv. Unable to create result set for query 'select * from dummy'. Invalid Fetch Size Unable to create result set for query 'select * from dummy'. Invalid Fetch Size java.sql.SQLException: Invalid Fetch Size".But I won't even go there yet.... for now I would settle with just knowing how to reference information in the Oracle external database provider...

How can i fetch records from 3 tables in a single query without using join

Hi.

Thanx

Hi Prabgudutta,
We can fetch the data by using the views concept.
Go throuth this info we can know the how to create view and same like database table only we can fetch the data.
Views conatin the data at runtime only.
Four different view types are supported. These differ in the
way in which the view is implemented and in the methods
permitted for accessing the view data.
Database views are implemented with an equivalent view on
the database.
Projection views are used to hide fields of a table (only
projection).
Help views can be used as selection method in search helps.
Maintenance views permit you to maintain the data
distributed
on several tables for one application object at one time.
step by step creation of Maintenance view:
With the help of the table maintenance generator, you are able to maintain the ENTRIES of the table in SM30 transaction.
It can be set in transaction SE11 - Tools - Table maintenance generator.
Table maintanance Generator is used to manually input values using transaction sm30
follow below steps
1) go to se11 check table maintanance check box under attributes tab
2) utilities-table maintanance Generator-> create function group and assign it under
function group input box. Also assign authorization group default &NC& .
3) select standard recording routine radio in table table mainitainence generator to move table
contents to quality and production by assigning it to request.
4) select maintaience type as single step.
5) maintainence screen as system generated numbers this dialog box appears when you click on create button
6) save and activate table
One step, two step in Table Maintenance Generator
Single step: Only overview screen is created i.e. the Table Maintenance Program will have only one screen where you can add, delete or edit records.
Two step: Two screens namely the overview screen and Single screen are created. The user can see the key fields in the first screen and can further go on to edit further details.
SM30 is used for table maintenance(addition or deletion of records),
For all the tables in SE11 for which Table maintenance is selected , they can be maintained in SM30
Sm30 is used to maintain the table ,i.e to delete ,insert or modify the field values and all..
It creates the maintenance screen for u for the aprticular table as the maintenance is not allowed for the table..
In the SE11 delivery and maintenance tab, keep the maintenance allowed..
Then come to the SM30 and then enter the table name and press maintain..,
Give the authorization group if necessary and give the function group and then select maintenance type as one step and give the screen numbers as system specified..
Then create,,,
Then u will able to see the maintenance view for the table in which u can able to insert and delete the table values...
We use SM30 transaction for entering values into any DB table.
First we create a table in SE11 and create the table maintenance generator for that Table using (utilities-> table maintenance generator) and create it.
Then it will create a View.
After that from SM30, enter the table name and Maintain, create new entries, change the existing entries for that table.
Hope this resolves your query.
Reward all the helpful answers.
