DBMS_DATAPUMP how to fetch completed_rows

Hi,
we are using data pump api to copy partition data to dump file. we need to fetch completed_rows (row count) for partition status monitoring. record count get generated in log file but we need to parse it again.
i refer below url
[http://download.oracle.com/docs/cd/B19306_01/appdev.102/b14258/d_datpmp.htm]
but unable to get the status, we are using below code for creating dump file.

Removed dbms_datapump.detach and now wokrs O.K - seems that dbms_datapump.detach + wait for job are mutually exclusive?
If you want your block to WAIT till datapump finishes, why are you detaching? detach means you are no longer interested once the job has started. Remove the detach and keep the wait_for_job as you have found out.

         '101525' is time in hour,miniute,second format.
From my program I can only pass directory , Folder name,System Id,Date only. I don't have time value in my program.

Do you want to return the file to the user on click of button or something?
Then, use web_show_document with http link which you are speaking about.
Else download the file to client using Webutil.

How to fetch accounting document number from known material document number

Hi,
Using MIGO transaction, by giving mblnr(material document number) as input, I get accounting document number by clicking FI document.I have to add this accounting document number in my report for corresponding known mblnr(material document number) values.
My question is how to fetch the accounting document number present in MIGO to add in my report program.
I used the xblnr(Reference Document Number) which is present both in mkpf and bkpf tables to fetch values.
I extracted xblnr values with known mblnr values from mkpf (Header: Material Document table).
and then extracted belnr(accounting document number) from bkpf (Accounting Document Header table) by using xblnr values.
But the query is running for a long time.
Is there any other method to extract the values in a simpler way.
Kindly advise.
Thanks and Regards,
Sanjeev

I had the values of xblnr and some other fields such as mblnr, budat etc in wi_item table.
I created a new internal table i_xblnr and got down those values.
And then created a new internal table i_belnr and tried to get values of belnr in it.
The code I wrote is given below:
IF not wi_item[] is initial.
loop at wi_item.
   at new xblnr.
    ws_xblnr-xblnr = wi_item-xblnr.
     append ws_xblnr to i_xblnr.
   endat.
endloop.
select belnr xblnr from bkpf into table i_belnr for all entries in i_xblnr where xblnr = i_xblnr-xblnr.
ENDIF.
Kindly look after it.Thank you.
Regards,
Sanjeev

OPEN my_CuRSR FOR

How to fetch data from different sources into one source (like into Ztable)

hi friends,
As per our client requirements they want to develope an Inventory and an Ontime delivery report in BO on top of Oracle database.
Situation is some thing like they have ECC 6.0.and they want to collect all inventory and ontime delivery data at one place.According to me that could be one Ztable in which we can gather all data.Apart from that they are going to use Data Integrator in which they can directly fetch the data from R/3 system(They dont want to have BI system) and put all data in Oracle DB.On top of ORacle BO person can develop BO reports.
My question is how to fetch all data at one place and what are the tables going to be use.
kindly help me out as its very important project.
Thanks
Abhishek

The following is my standard reply to those who need to get old data from a backup in one account and add it to another account. The method described here may be applied to your case. It would be a bit of a long process, though.
When connected to the account you want to GET data from, Go to Settings>iCloud and turn all data that is syncing with iCloud (contacts, calendars, etc.) to Off.
When prompted choose to keep the data on the iPhone.
After everything is turned off, scroll to the bottom and tap Delete Account. Next, set up a new iCloud account using a different Apple ID and turn iCloud data syncing for contacts, etc. back to On. When prompted, choose Merge. This will upload the data to this new account.
Note that this only affects the "Apple data" like contacts, calendars, reminders, etc. Many third party apps also use iCloud to store data files there. These files may be lost in the process, unless the apps also keep the data locally on the device.
NOTE: Photos in the photo stream (if you use it) will not transfer to the new account. It is advised that you save the photos to a computer before performing the account switch.

How to fetch some certain records at a time

fethch all the records at a time.
example, every time I only want to fetch 10
records. Does anyone know that?
thanks

I think you may be getting setFetchSize(int) and setMaxRows(int) confused. I may have added to the confusion with my breaking out of the loop comment.
setFetchSize(int) gives the driver a hint as to how many rows it should store in memory at a time internally, ie. within the driver. It has no real effect on how you write your program at all. Its only purpose is to limit memory usage by the driver. To limit the rows returned, use setMaxRows.
For example, assume a result set has 20 rows and you use:
rs.setFetchSize(5);
while (rs.next()) {
System.out.println("Rows: " + (++count));
} You still get a count from 1 to 20. However, internally the driver is only holding in memory 5 records at a time, after the 5 returned it will discard those and get the next 5. So instead of holding 20 rows, its only holding 5 at a time. If you change rs.setFetchSize(5) to rs.setMaxRows(5) you will only get a count from 1 to 5, the rest are silently discared and rs.next() returns false.
Check your documentation to see if your driver supports the method. I believe many drivers don't. If not, I believe there is no way around multiple queries. Even if there is no rowid, as long as you order your queries you should be able to start again where you left off.
Disclaimer: Both drivers I commonly use do not implement setFetchSize(int). Someone let me know if I've fudged something here.
Good Luck

I need to send back exact error message to client to debug the messages.
How to fetch the messages, line number etc.
By seing docs i wont be able to figure it out.
Can any one send piece of code to fetch the error messages.

If you access the FacesContext you find a method called
getMessages()
Return an Iterator over the FacesMessages that have been queued, whether or not they are associated with any specific client identifier.

How to fetch data for the Change Request in PROCESS_EVENT

Hi All,
I need to write some custom logic on Save/Submit button. For this I am planning to enhance the PROCESS_EVENT method of class CL_USMD_CR_MASTER. Within this method I need to access runtime data of the change request currently being processed.
I am going to create a post-method exit for this PROCESS_EVENT method. Is this correct?
I have heard we have APIs in MDG which can be used to fetch data, however I do not know how to use the same.
Can someone please help me with sample code how to fetch the runtime data of the Change Request
Thanks in advance.
Regards,
Vanessa

What MDG domain are you working on? What you are trying to do is called "reuse mode" enhancement and you do NOT want to tinker with the FPM feeder classes in this case. SCN document Configuration and Enhancement of SAP Master Data Governance contains many examples on how to achieve this.
This is a how-to document for MDG-M reuse mode enhancement: Extend MDG-M Data Model by a New Entity Type (Reuse Option)
This is a how-to document for MDG-C/S reuse mode enhancement: SAP How-To Guide: Extend the MDG Business Partner - Node Extension (Reuse Option)
Keep in mind, these examples are mainly for additional "master data" fields. If you need additional fields that are not master data but are more related to the Change Request itself, you should use this how-to document: Enhancement of the User Interface Building Block for Change Requests
Again, all of these documents can be found on the first document I referenced above. I suggest that you bookmark it.

How to dynamic order of groups & How to fetch data at runtime from database

Post Author: ferikpatel
CA Forum: Formula
I am using visual studio .net application having inbuilt crystal report feature. Now, what I want to do is, i have create 5 groups in crystal report, but dynamically want to change the order of those reports as per user's selection.
How to do that?
Also, how to fetch database item on runtime which is not selected through data expert as its relation is depends on situation. Say if one field's value is 5 than i want to get name of customer, but if same field's value is 6 than i want to get name of suppliers. In database both supplier and customers tables are different however they are connected with base table.
I'm bit new in crystal report. Please help me out if it is possible.

You don't actually change the order of the groups. You group on a formula and change contents of the formula based on the parameter.
IF {?Group1} = "Manager" then {table.Manager}
else if {?Group1} = "Invoice Date" then Totext({table.InvDate},"yyyyMMdd") note all options must be the same date type, so numbers and dates are converted
else . . .

How to fetch the data & display the data if fields got the same name in alv

Refer the url :
http://abapexpert.blogspot.com/2007/07/sap-list-viewer-alv.html
Go thru the guide for OOPs based ALV.
Use SET_TABLE_FOR_FIRST_DISPLAY to display the table:
CALL METHOD grid->set_table_for_first_display
EXPORTING
I_STRUCTURE_NAME = 'SFLIGHT' Structure data
CHANGING
IT_OUTTAB = gt_sflight. Output table
You can also implement
Full Screen ALV, its quite easy. Just pass the output table to FM REUSE_ALV_GRID_DISPLAY.
For controlling and implementing the FS-ALV we have to concentrate on few of the components as follows :
1. Selection of data.
2. Prepare Layout of display list.
3. Event handling.
4. Export all the prepared data to REUSE_ALV_GRID_DISPLAY.

In Select query how to fetch values through multiple parameters where conditon

Dear Experts,
I have one table(T) with 4 fields: f1, f2, f3, f4. In that based on f2, f3, f4 and parameter condition( f2 values) how to fetch f1 values. I have attached screen shot. What is the where condition in select query?
DATA: it_T type standard table of ty_T,
          wa_T type ty_T.
parameters: p_f2_1 type T-f3,
                  p_f2_2 type T-f3,
                  p_f2_3 type T-f3,
                  p_f2_4 type T-f4,
                  p_f2_5 type T-f4,
                  p_f2_6 type T-f4.
select f1 f2 f3 f4 from T into table it_T where ?
What is the where condition ?.
Regards,
Abbas.

Hi Syed,
Do all the parameters p_f2_1 ... p_f2_6 contain values for the same field f2? And do you need all the entries from the table T which contain f2 = any of the entered value? If yes, Then you can try the following where condition -
select f1 f2 f3 f4 from T into table it_T
where f2 = p_f2_1 OR
             f2 = p_f2_2 OR
             f2 = p_f2_3 OR
             f2 = p_f2_4 OR
             f2 = p_f2_5 OR
             f2 = p_f2_6.
P.S: If any of the above parameters are optional as per your requirement it will be better to build a dynamic query and use it in the where condition.

Rachna.
