Restrict the number of records to be fetched

Hello Gents,
The situation is like this, I have a report on Oracle reports 6i which fetches 2+ million records and it takes lot of time to generate,
I’m not sure whether it can be handled in discoverer because the report has some validation procedures (Program Unit) and triggers.
I want to restrict the number of records to be fetched in groups; I have gone through of Oracle online help
1. Group Filer: Filter fetches all records from database and displays only the number of records which is set to the property
2. Maximum Rows to Fetch: This property fetches only the number of records which is set to the property.
I want to fetches records incrementally; I don’t want to keep resources busy
Is there any property similar like Discoverer “Retrieve data incrementally in groups of” or any workaround?
Help or any advice is appreciated

If you generate a pdf, it has to fetch all records for pdf.
If its in previewer: do you display total number of pages on the report?. If yes, >remove that and see how it comes. Other options are tunning queries and gather >the data into temp table before displaying it on the report. No, I'm generating a pdf
No, the report is not having display page no on it.
If I would have to create temp table, I would have used discoverer instead
Is there any property in reports to restrict the query to get the data in groups?
Any advice appreciated.

How to restrict the number of Records into the Table?

Is there any way that I can restrict the number of records can be entered into the table?
For example I have created a table TAB1 with size category 0( zero).
User dont want to enter more than 100 values, How to restrict the number entries? Whether Basis can do it?
Regards,
Prathap

Hi Prathap,
You can write a code in table maintenance events to restrict the number of Records added into the Table to constant.
Solution:
Se11 -> enter table name (TAB1) -> F6 -> Utlities -> Table maint. generator -> Envirnment -> modification -> events -> write here the form routine name.
Double click on routine name. You will get into include section of the code. Write here code like:
IF current_rec_num > 100.
messgae error 'Entry restriceted to 100'
ENDIF.
Somewhat this way you can achieve your target.

Can we specify limit on the number of records to be fetched?

Can we specify limit on the number of records to be fetched from the database?
I have millions of records in my DB and I want to fetch say some 50,000 latest records to optimize the performance of reports.
Is it possible in any version of Crystal Reports?
Regards,
Amrita

Hi Amrita
Do you have any groups in your report. If yes then this is what you need to do:
1) Insert a section below on the Details section so that there is a Details A and Details B.
2) Create the following formulas:
@Formula1
WhilePrintingRecords;
NumberVar Number := 0;
@Formula2
WhilePrintingRecords;
NumberVar Number;
Number := Number + 1;
3) Place @Formula1 in the Group Header. Format the formula to Suppress.
4) Place @Formula2 in Details A. Format the SECTION (not the formula) to Suppress.
5) Format the Details B section to conditionally Suppress by selecting the X+2 button INSTEAD of the selecting the Suppress box. This launches the conditional formatting Formula Editor.
6) Enter this formula:
{@formula2} > 3
When you preview the report you will only see 3 records per group.
Let us know if you need any further help with this.

Fetching the number of records in a multi-record block...

Hi ,
In Forms10g runtime-and in previous releases too- there is , as a message, the number of records fetched/inserted in a multi-line block such as Record:5/9. Is it possible to catch these two numbers (i mean 5 and 9 , or at least the number of records)...not only in query but in the insert mode as well...?????
Many thanks ,
Simon

No, you can't capture that text, but you can write your own code to do the same thing.

How to find the number of records in ods?

how to find the number of records in ods?
Pls suggest the solution apart going to the table of ods and seeing the number of records.
Is there any program or function module to see the number of records in ods?
For eg: SAP_INFOCUBE_DESIGNS is a program which gives the detail (number of records) of infocube.

Hi,
I was looking at this and found the following tables that may be of help.
One of these tables will include a summary of the record count of all the tables in your system based on the last time each table had it's database statistics calculated:
DBSTATTADA
DBSTATTDB2
DBSTATTDB4
DBSTATTDB6
DBSTATTINF
DBSTATTMSS
DBSTATTORA
We run on an Oracle database so the table record counts can be taken from DBSTATTORA. Type in AZ in table selection field in SE16 to restrict the output to ODS (or DSO) tables only.
The record count is at the time indicated in the timestamp field. Obviously this is not real time but should not be too out of date - if it is you may be having performance issues and should get your DBA / Basis to run a full refresh of DB stats.
Hope this helps, alhtough not real time the table should give you a decent indication of the size of all your ODS objects (or any other table for that matter!)

Limit the number of record to download to excel from a report

I am just wondering if there is a way to limit the number of rows that I want to download to excel from a report in apex, right now when I click download to excel it downloads all records. If I am displaying 15 records on report page I want the ability to download only those records.
Any help with that would be appreciated.
Kind Regards,
Sofia.

Sofia,
The same report query runs for downloading the data into excel, I don't think you can limit the number of records in download.
You can achieve it using custom code, like on click of download excel redirect to another page and then restrict the data as per your need, or you can use the custom procedure to download the limited data.

Limitting the number of records in query

I like to limit the number of records retrieved in the query. I set Query All Records block property to NO, Query Array Size to the number I want to retrieve. Before doing that, I set form Preference - Array Processing checked. The result is form always retrieves all records meets the search condition. Could someone tell me what's wrong with it?

I do not understand why and what exactly you want to do. The query array size defines the number records your form should fetch at a time, i.e. if you have 100 records in the database and you set the array size to 20, forms will perform 5 fetch cycles to retrieve all records. However, this is transparent to the user and he will see all 100 records. This property is used for performance tuning when working with a large volume of records.

Restrict the number of output rows

I'm using Crystal XI.
Is there a way to restrict the number of ouput rows comparable to a SQL "Set Rowcount" command? If so, I would appreciate the instructions.
Thanks.

I don't think their is a way to do it through the select expert, but it's easy enough to suppress any records beyond a defined number through the section expert:
recordnumber > 5
Any records after 5 are suppressed.

How to find the number of records per months in cube

Hi,
how to find the number of records per months for my all cubes?
Can i use the ListCube transaction to find totl number f records per cube monthwise ?
Jimmy

Hi,
Here is a program to generate no of records and list of ODS and Cubes in Active version.Schedule this program in background and create a cube to load this information and schedule to the data from the file generated by the program. Schedule this all per you requirement.
1.Copy the code into your Z<programname> from Se38.
2.change the FILENAME in CALL FUNCTION 'GUI_DOWNLOAD' in the program to the location from where you can pick the information to load data to cube(eg Application server).
3.Save program.
4.Schedule the program in background as required
5.Create cube with infoobjects to hold no of records and Infoprovider name
6.Load this cube based on event after the program job is done.
Hence you can report on this cube to see no of records in CUBE or ODS in your box.
Please find the code below.

How to limit the number of records in WebI Report

Hi,
I have a requirement where I need to display the WebI Report data only if the number if record is less than 65k.
Incase if the records are more than 65k then the report should be blank and a text message needs to be displayed.
The client dont want to set the number of records either in universe or at the edit query at the report. They want to limit once the report is executed.
Please let me know if its possible to do it at the report level.
Thanks in advance!!
Best Regards
SAP BO

Optional prompts are not a problem.
Assuming you first query uses the following SQL statement
select a,b,c from t where x=y and z=@prompt(...)
The query for checking the number of rows should use the following SQL code
select count(*) from t where x=y and z=@prompt(...)
The original query should be modified as follows
select a,b,c from t where x=y and z=@prompt(...) AND (select count(*) from t where x=y and z=@prompt(...)) < 65000

How to calculate the number of records in Multiprovider

Hi Experts
I have created a report based on the multiprovider (Consist of Cube and ODS)
I need count the number of records inside the multiprovider, how can i do it in the reporting level
Regards
Santosh

Hi,
You can use calculated key figure with replacement path variable.
Follow This:
1) From the context menu of the Key Figure directory, choose New Calculated Key Figure.
2) From the context menu for the Formula Variable, choose New Variable.
3) Choose the Processing type as Replacement Path.
4) In the next screen, select the Characteristic Info Object based on which the number of documents is to be displayed in the report (For example: Document Number / Order Number).
5) Choose Next.
In the Replace Variable with drop down box, choose Attribute Value.
In the Attribute drop down, select Characteristic Reference (Constant 1).
6)Choose Next.
On the Save Variable page, an overview of the settings made for the variable will be displayed.
Confirm the entries and Choose Finish.
7) If the Formula variable is directly assigned to the Calculated Key Figure, a warning Calculated Key Figure is not defined correctly will be displayed while executing the Query.
8) Properties of Calculated Key Figure dialog box, assign a Technical name for the CKF.
9) set the Time of Calculation to After Aggregation.
Hope this will help you.
Cheers,
DK

How do I count the number of records returned in the CMIS query

How do I count the number of records returned in the query CMIS?
SELECT COUNT(*) FROM ora:t:IDC:GlobalProfile WHERE ora:p:xRegionDefinition = \'RD_PROJETOS_EXCLUSIVOS\''}
Euler Homero

Hi Euler,
interestingly enough, the reference guide for CMIS ( http://wiki.alfresco.com/wiki/CMIS_Query_Language ) that I found does not mention the COUNT function at all. On the other hand it states that: "The SELECT clause identifies which virtual columns to return in the result set. It can be either a comma-separated list of one or more queryNames of properties that are defined by queryable object types or * for all virtual columns."
There are, however, some other posts like e.g. http://alfrescoshare.wordpress.com/2010/01/20/count-the-total-number-of-documents-in-alfresco-using-sql/ which state that they could make it working.
Having asked in the WebCenter Portal forum, I assume that your content repository is WebCenter Content. The CMIS doc for the Content is available here: http://docs.oracle.com/cd/E23943_01/doc.1111/e15813.pdf (no COUNT there either). It does, however, mention explicitly that "CMIS queries return a Result Set where each Entry object will contain only the properties that were specified in the query.". This means your could rather investigate the Result Set. Note that there are also other means than CMIS how to get the requested result set (e.g. calling a search service directly via so-called RIDC).
In the given context I am also interested what your use case is. OOTB CMIS in WebCenter Portal is used, for instance, in Content Presenter, where it is content rather than "parameters" what's displayed.

Any table or program to get the number of records in P, A and F tables

HI all
any table for program to get the number of records in P, A and F tables. I want to create SQ01 queries to get the status of number of records. We are gng for a production cutover next week. Want to capture all the data before and after Upgrade cutover.
Also suggest me how to create sq01 queries.
Thanks in advance

Use Transaction LISTSCHEMA to see all the tables assosciated with ur cube
Total number would be what you find in both the E & F fact tables. If there is no compression in the cube then E table will be empty.
Alternatively u can use se16 transaction and enter E table and F table manually
E table - /BIC/E(Cube name) and Ftable - /BIC/F(Cube name)
Or else u can go to the manage of the cube and without selecting any field for O/P and ticking the option output number of hits execute. The total of Row Count will give u the total no of records in the cube.

BAPI to find the number of records existing in HR module

Hi ,
I wanted to know if there exist BAPI that would return me the number of SAP HR module users in a system.
I cam across the BAPI's for info types like personu2019s Personal Data (Infotype 0002)
BAPI_PERSDATA_CHANGE u2013 Change personal data
BAPI_PERSDATA_CREATE u2013 Create personal data
BAPI_PERSDATA_CREATESUCCESSOR u2013 Create subsequent personal data record
BAPI_PERSDATA_DELETE u2013 Delete personal data
BAPI_PERSDATA_DELIMIT u2013 Delimit personal data validity period
BAPI_PERSDATA_GETDETAIL u2013 Read personal data
BAPI_PERSDATA_GETDETAILEDLIST u2013 read instances with data
BAPI_PERSDATA_GETLIST u2013 Read instances
But i wanted to know if there exist a master table which would return me the number of records irresepctive of the infotypes.
Best Regards
Manoj

Hi,
if you want to know the number of employees, then u should use the infotype PA00001 and PA0000 with appropriate criteria. Infotype PA0002 should not be used to find the number of employees in the HR.
As you requested there are no specific BAPI to find the records. Hope this helps you.
Or u can use PAR2 transaction to find details.
Thanks,
