UPDATE statement not working when updating Z table

Hi
I have declared Ztable with fields MANDT, VKORG, VBELN, IDENTCODE and POSNR as key fields, other fields are FKDAT,KUNNR, NETWR, WAERK, SKFBP
First I got the data from presentation server and moved into internal table 'A' and after that declared internal table with structure same as Z table and moving the data from presentation server internal table 'A' into this.
After Endloop I am using statement
UPDATE ZVS_INV FROM TABLE IT_INV.
commit work.
But table is not getting updated and sy-subrc is returning to 4.
What could be the reason...your help appreciated.

howcan it make difference if the primary key is defined as per my business requirement
Just because the business requirement 'says so', doesn't mean that's it's right. You appear to be maintaining a Z-table with a subset of billing fields and appear to have 'over-specified' the primary key.
As far as the help files, if you did look at them, I don't think you took the time to understand before just posting your problem here. An UPDATE operation is a very simple operation. You gave the answer to why it didn't work in your comments as Keshav already pointed out...

UPDATE statement not working

Hi,
I want to modify the record of PA0009 .I want to change the enddate of personnel No.
UPDATE PA0009 SET ENDDA = '30.10.2009'
WHERE PERNR = '1'
AND BEGDA = '01.09.2008'.
The above statement is not working. How to modify the enddate which is part of key table.
Please guide.
Thanks and Regards
K Srinivas

Hello,
Set the data format to the internal date format (YYYYMMDD), so in the set and the where clause pass '20091030' as ENDA which is to be changed and BEGDA in the where clause as 20080901. Also if the after the changes if the key combination results in dupicate records then the update will faiil. Just make sure that the combination of PERNR,SUBTY,OBJPS,SPRPS,ENDDA, BEGDA and SEQNR remains unique, if a record exists with this combination then sy-subrc will be 4 and the record will not be updated.

Sachin

Update statement not working PL/SQL block

Hi friends,
My code is written the following way:
declare
var1 number;
var2....
Cursor c1 <select something>;
Cursor c2 <select something>
Begin
Insert into table1 <different values>;
Commit;
/* first update statement */
Update table1 set table1.col3 = (select col3 from table2 where table2.col1 = table1.col1 and table2.col2 = table1.col2);
commit ;
/* 2nd update statement */
update table1 set table1.col4 = (select col4 from table3 where table3.col1 = table1.col1 and table3.col2 = table1.col2);
commit ;
for r2 in c2 loop
update table1
end loop;
end;
This code works till 1st update statement. But after that, even if I let my code run overnight, nothing happens. There are appropriate indexes on tables where join is done. All tables are in one schema.
What could be the reason?

darshilm wrote:
/* first update statement */
Update table1 set table1.col3 = (select col3 from table2 where table2.col1 = table1.col1 and table2.col2 = table1.col2);This is an unconstrained updated - meaning that it instructs the database that every single row in TABLE1 needs to be updated.
For every single row, the "update" SQL has to be executed and a SELECT performed on TABLE2.
Let's say there are a 100,000 rows in TABLE1. This means that the SELECT to find the updated value has to be executed a 100,000 times.
Let's say that there are a 200,000 rows in TABLE2. This means that each time that SELECT runs, it potentially hits 200,000 rows. Does it do it via a full table scan? Index range scan?
At what cost? Hitting the very same data set again and again and again, 100,000 times in a row.
And that is only the start of your code... and you wonder why it does not seem to finish?
Data processing in a RDBMS is about how to do the minimal amount of I/O to achieve the desired result. For example, instead of hitting TABLE2 100,000 times, you can write code to hit it once by joining it with TABLE1 and creating an "updateable view" of TABLE1 that can be updated with the join values of TABLE2.
You also seem to use PL/SQL cursors to perform row-row (and slow-by-slow) processing. This typically pulls data from the SQL engine into the PL engine and then push that very same data from the PL engine to the SQL engine.. It is a lot faster and more efficient (and scalable) to rather stay inside the SQL engine and do data set processing there (as oppose to row-by-row on the client side).
Performance in a RDBMS is primarily determined by the designer and the developer... are functions of how well designed the data model is, and how well designed and written the code is.

Workstation Bridge not working when Updating from 10041 to 10049

I am using Workstation 11 on a Windows 8.1 Host
All works well including Bridge network connections
I loaded Windows tech Preview 10 version (before 10041)
All worked apart from the Bridged network connections when using VMware workstation 11
Then there was an update to 10041 and the bridged connection started to work but you could not access the physical network card on the host...some error
Then somewhere the new update version was installed on my machine to version 10049
Now I cannot configure bridge mode in my VMware workstation 11 it tells me there sre no un bridged host insdtsalled and when I look at the physical network card there are no protocols installed.
Looks like I will have to go back to windows 8.1 pity
When one thing is fixed another is broken

I too has the same issue and I apprently tried to revert to 10041 from 10049 and it did not work.
But I tried to these and it worked for me. I stopped all the VM's and in vmware networking removed all the adapters.
Then tried to run the vmware 11 (latest) setup again and when it asked to install I choose repair and it did repaired and reinstalled the networking and after that I tried to create new virtual adapter and it worked and vm can able to browse internet.

Audio Not Working when updated to Windows 8.1

I had just updated to Windows 8.1 but my audio does not work. the Beats Audio Control Panel does not open and i dont have any sound whats so ever. I have an HP Pavillion 1451 Desktop and have done everything possible to fix this. I've tried links like these http://h10025.www1.hp.com/ewfrf/wc/softwareDownloadIndex?cc=us&lc=en&softwareitem=cp-124030-1 to download a new driver but it always fails. What else can I do?

Hi:
While trying to help you, I was looking along the same lines as you were (I assume).
I did a search by the IDT 92HD73E audio codec and all I could find were drivers for system boards with Intel processors such as the driver you tried unsuccessfully.
I have finally found a W8.1 driver for that codec from a desktop PC with an AMD processor and chipset.
See if this one works...

Rollover states not working when published online. Suggestions?

I have created rollover states for image navigation. Works great in preview. Works great when published to desktop. I have uploaded to FTP site. Some of the rollovers work, others do not.? I have replaced and re-uploaded, still not working. The normal and active states all work, but the rollover state vanishes. The images are in the image folder. The css pages do have the code to swap the images. Same issue in Chrome, Safari, Firefox, and on ipad.
What am I missing? Thank you for your help!

UPDATE statement not working as expected

In our table we have a field with length of nvarchar(70) which is used to store multiple values that can be queried using SUBSTRING. There are already 54 characters in the field including the final quote.
The Start and end characters of the field are always a single quote.
I need to update the field, adding up to 3 characters from another reference table.
I tried the below, but it is missing of the last character when the number is greater than 9.

Software update does not work when I try to update from OSX 10.6.8 to OSX 10.7. How do I update?

How do you update from OSX 10.6.8 to OSX 10.7? Software update app does not perform update.

That's because 10.7 is not an update, it is an upgrade that you have to buy by using the App Store app, not by using the Software Update.
It costs $19.95: http://store.apple.com/us/product/D6106Z/A/os-x-lion

Insert statement not working when Interface is run through PI ..

Hi Every one,
There is an interface(Server proxy) which updates a ztable in the program. Updates are happening when we are running this interface manually(putting Payload manually) but in case there are already entries in ztable and we are trying to update these records, even after handling exception z table is not getting updated when run through PI and happening manually.
Please suggest me for the same.

Tobias from this forum had the answer!
http://powershell.com/cs/forums/p/5438/8786.aspx#8786
His fix:
Whenyou putput text from powershell, the console width is assumed. Since task scheduler runs its own hidden console, the width of that console is used to truncate the text.
You can work by this issue by setting the width yourself. Try using a combination of Format-Table -auto / Format-List -auto and Out-File -width like this:
get-process | Format-Table -Auto | Out-File c:\test.txt -Width 10000
The format-cmdlet with -Auto makes sure the file uses only as much width as is truly needed. The -Width parameter sets the maximum width available.
If you must redirect the output to something else, replace Out-File with Out-String -Stream -Width 10000 and then redirect the result to whereever you want.
Note that multiline strings will still be truncated after the first line.
My code looks like this:
#Export Dataset Table to a text file
$DataSet.Tables[0] | Format-Table -Auto | Out-File $rcvrFileName -Width 10000
This worked like a charm.
Thanks!

Abap Logic for performance tuning not working when using Internal tables

Hi,
I wrote this piece of code that is working correctly that is select SUM of cost from DSO where Plant is the same for Sales Items.
LOOP AT RESULT_PACKAGE INTO rp.
SELECT SUM( /N/S_STRDCOST ) FROM /N/ADSP_DPIT00 INTO
rp-/N/S_STRDCOST
WHERE /N42/S_SALESITEM = rp-/N42/S_ITEMID AND /N42/S_PLPLANT EQ
rp-/N42/S_SOURCE.
MODIFY RESULT_PACKAGE FROM rp.
Clear rp.
ENDLOOP.
Now I try to rewrite it for performance tunning using internal table but I am getting 0 values. can't figure out whats the problem and been struggling fixing it.
TYPES : begin of ty_DSO_TABLE,
         /N42/S_STRDCOST TYPE /N/ADSP_DSPC00-/N/S_STRDCOST,
         /N42/S_ITEMID TYPE /N/ADSP_DSPC00-/N/S_ITEMID,
       end of ty_DSO_TABLE.
DATA: it_DSO_TABLE type hashed table of ty_DSO_TABLE with unique key
/N/S_ITEMID,
     wa_DSO_TABLE type ty_DSO_TABLE.
Field-symbols: <rp> TYPE tys_TG_1.
LOOP AT RESULT_PACKAGE assigning <rp>.
clear wa_DSO_TABLE.
Read table IT_DSO_TABLE into wa_DSO_TABLE with table key /N/S_ITEMID
= <rp>-/N/S_ITEMID.
if sy-subrc ne 0.
      select SUM( /N/S_STRDCOST ) into CORRESPONDING
      FIELDS OF wa_DSO_TABLE from
      /N/ADSP_DPIT00 WHERE /N/S_SALESITEM = <rp>-/N/S_ITEMID AND
      /N/S_PLPLANT EQ <rp>-/N/S_SOURCE.
     if sy-subrc eq 0.
          <rp>-/N/S_STRDCOST = wa_DSO_TABLE-/N/S_STRDCOST.
     endif.
endif.
ENDLOOP.
Any idea whats wrong with the code
thanks

Hi Vaidya,
According to the code which you have written, there is no value in table IT_DSO_TABLE when you are trying to read the values.And after the read statement you have given a condition for sy-subrc. Hence the select statement is actually not even getting executed. *Also you have not assigned the final value back to the ResultPackage.*_
So Kindly correct your code as follows:
Data: wa_dso type ty_DSO_TABLE.
LOOP AT RESULT_PACKAGE assigning <rp>.
clear wa_DSO_TABLE.
select SUM( /N/S_STRDCOST ) into CORRESPONDING
FIELDS OF wa_DSO_TABLE from
/N/ADSP_DPIT00 WHERE /N/S_SALESITEM = <rp>-/N/S_ITEMID AND
/N/S_PLPLANT EQ <rp>-/N/S_SOURCE.
if sy-subrc eq 0.
<rp>-/N/S_STRDCOST = wa_DSO_TABLE-/N/S_STRDCOST.
MODIFY RESULT_PACKAGE FROM <rp>.
endif.
ENDLOOP.
Hope this helps you.

Satyam

Track Changes colors not working when story contains table

Can anyone duplicate this problem/bug, or let me know if it is just my machine?
Steps to reproduce
Make sure your Edit > Preferences > Story Editor has non-black text colors defined for Added Text, Deleted Text, and Moved Text.
Create document, and draw a text box
Inside the text box, Right-click > Fill with Placeholder Text
With the cursor in the text box, turn on Track Changes and Show Changes from the Track Changes pallette:
Open the Story Editor with Ctrl/Cmd-Y
Cut/paste, delete, and insert some text.
Confirm colors appear in Story Editor as defined in step 1:
Now insert a table anywhere in the story. For me, all non-black text coloring (bg stays fine) disappears:
Is this an InDesign bug, or something I'm experiencing on my own machine? I've been able to duplicate the issue in InDesign CS6, InDesign CC and InCopy CC on my Win7 Pro 64-bit machine.

I'd recommend filing a bug report here to make sure it gets reported:
