Se16n check buffer.

hi experts,
today i delete a domain ( b ) value, and when i use se16n to change the data for field c with domain b,
but the message invalid message come, and there is no foreign key for this field. i also use se14 to adjust database and force conversion this table.
it's very strange, i guess the murderer is buffer, but could any body tell me if there is a tcode to refresh this buffer?
btw: when i use another languge to logon sap ,it can change.

For reference, those codes can be found in 26171 - Possible entry values for command field ("OK-code") . Also note that using this code you reseted the whole table buffers of the application server, so a little (or not) down-performance (as after a server reboot)
You could use transaction AL12 (-> Menu "Statistics" -> Buffers -> Generic Key Buffer -> Single Object -> Tabname = 'DD07V' -> Display) then (from OSS note 1825838)
AL12 -> Menu "Edit" -> Reset Buffer -> Gen. Key Buffer ... -> In the displayed dialog box in the section "Single Table" specify the table that you want to displace from the buffer and execute the function "Remove".
Afterwards, you can reload the table again and the subsequent SELECT statements can be handled by the buffer.

Raymond

Transport request : tp check buffer for already imported requests

Hi,
I want to put a transport request on my prod. There was no problem on the quality. But on the prod, i have the message :
"tp check buffer for already imported requests"
and nothing appends.
Do you have any idea how i can unlock this transport request ?
Tx in advance.

Hi,
Use table E070. and display the Transport reqeust and double click on the request row.and in command prompt enter ' /h '. change status as unreleased.

Return vector for points done of check buffer status in onboard program

Background
I am trying to develop a trigger application based on the current position of a contour profile.
I can not use breakpoints as the application is using hydraulic cylinders with analog feedback
for the primary position. In order to make sure the trigger happens relative to the motion regardless
of host load I want to run the application as an onboard program.
My idea is to read the buffer status points done and generate a pulse out as a trigger when the
points done is greater than the programmed trigger point. For example if I want to trigger on the 42
point of a 100 point profile, I would read points done of the main contour buffer. When points done
is greater than or equal to 42, I would generate a short pulse as a trigger.
Question
My problem is, I cannot find the order that the check buffer status VI returns the data to an onboard program
return vector. As I understand it, I need 3 variables to hold the returned data. One each for State, Backlog, and
Points Done. If I set the return vector to 10, does State get stored in 10, Backlog in 11, and Points done in 12, or
is there a different order?
If you could provide the return vector mapping order for all the motion VIs, it would be greatly appreciated.

Hello,
This is a very good question. I checked in the help for the LabVIEW VI, and it does not explicitly state the answer. The VI calls the FlexMotion function "flx_check_buffer_rtn". In the "NI-Motion Function Help" (Start>>Programs>>National Instruments>>NI Motion>>Documentation), the information for the functions states that it "...returns data in the following order: backlog, bufferState, and pointsDone." It also tells you the size of each of the elements. I will be filing a report so that the LabVIEW documentation includes this information in the future. I hope this helps. Take care!

Buffer Hit Ratio % -- Whats the right query ?

Whats the right query to track Buffer Hit % ;
Using this :
prompt BUFFER HIT RATIO %
prompt ===============
select 100 * ((a.value+b.value)-c.value) / (a.value+b.value) "Buffer Hit Ratio"
from v$sysstat a, v$sysstat b, v$sysstat c
where
a.statistic# = 38
and
b.statistic# = 39
and
c.statistic# = 40;
Buffer Hit Ratio
99.9678438
However, using this :
Select
Round((Sum(Decode(name, 'consistent gets',value,0)) +
Sum(Decode(name, 'db block gets',value,0)) -
Sum(Decode(name, 'physical reads',value,0))) /
(Sum(Decode(name, 'consistent gets',value,0)) +
Sum(Decode(name, 'db block gets',value,0)) ) * 100, 4)
from V$sysstat;
Comes up as : 67.7069 %
So which is the right one ?
Thanks.

Try running the following query:

        v$sysstat
where
        statistic# in (38,39,40)

                'physical reads',
                'db block gets'
;The you will understand the point the previous answer was making. It's a bad idea to rely on things like the statistic# being consistent across different versions of Oracle - names tend to be safer.
But neither query is correct. If you want any sort of vaguely meaningful "buffer cache hit ratio", you should be quering v$buffer_pool_statistics. See also: Re: Testing of buffer cache reveals these results: and http://jonathanlewis.wordpress.com/2007/09/02/hit-ratios/

Linking axis to saved buffer in ROM after initialization with 7356

Can you please help?
I can't seem to re-connect an axis to a saved position buffer in ROM after initialization/reset of board.
Details:
When I make a position buffer and save to ROM and then repeatedly run motion command (after using the conifgure buffer.flx with buffer size 0) the motion works just fine. If however, after saving this buffer to ROM, I do some setting changes/initialization ect, then I can't seem to reconnect to this existing buffer in the ROM (I checked and it is there via measurement and automation explorer). So, how do I re-connect to this buffer?
My system specs: Using windows XP sp2 with Labview 8, and the motion card is the PCI-7356.
Thanks very much.

Hi Richard,
I have attached my working VI to this reply. I tested it, and it
works after a reset and reinitialization of the motion controller board.
In the Connect to Buffer and Move portion of your VI, you must
reconfigure the Operation Mode for Absolute Contouring. After a
reset, the motion controller board will have a default Operation Mode
of Absolute Position, so you must change it back to Absolute
Contouring. You must also input the correct number of Total
Points to the Configure Buffer function. The correct number of
Total Points is the size of the array in the selected buffer.
Make sure that the Measurement & Automation Explorer is CLOSED when
you run this program. If MAX is open, its Object Memory Manager
will be making calls to Check Buffer which will conflict with this VI
and cause errors.
I also added Motion Error Handler VIs, so you can monitor any motion errors that might occur.
Sorry for the delay. Hope this helps!

SAP system checks

During system checks, a Baisis administrator will check Buffer swaps under Export/Import Hit ratio, programs etc. What is the importance of checking these?

Hi,
Normally in SAP the buffers are used to store the SAP object/data from DB. This is done for easy access of data when the users need them, it helps to increase the performance of the system by decreasing the I/O of system i.e, when the user requests data the work process first checks the buffers for the data requsted by the user, if it finds it there then it returns to the user with the data thereby increasing the speed of the access and in turn the performance. If the data is not found in the buffer a physical access to DB is made thereby increasing the response time and lowering the performance. After the data is fetched and returned to the user a copy of the data is put into the buffer, this helps to increase the access when some other user requests the same data as said above.
This mechanism is accomplished when you have a better buffer size, if your buffer size is very small the data put into the buffer will be pushed out to accomodate the new data, the red color indicates the no.of objects swaped out from the buffer to accomodate the new object in the buffer.
In your case the buffers needs to be increased to accomodate more objects in them, keep in mind that performance tuning needs more analysis and skill.
Changing Buffer parameters involves more calculations and might lead to poor performance if done wrongly or prevent the system to start since you have to restart the system in order to make the profile parameters related to buffers active.

Questions on V$BH

I learnt that V$BH can tell us contents of buffer cache. I looked up 11.2 document b28329. It saysV$BH displays the status and number of pings for every buffer in the SGA. This is a Real Application Clusters view.Questions:
1) Is v$BH not good for single instance, since it is a Real Application Clusters view? I did see the view in non-RAC and query it returning lots of rows. Are the result meaningful
2) The phrase in Oracle Doc is hard to understand as usual. Does 'number of pings for every buffer' means those buffer cache blocks that are pinned in SGA, or just every block of buffer cache?
I used ALTER SYSTEM FLUSH SHARED_POOL to clear buffer cache in a single instance, and check buffer cache before and after the clearing buffer with queryselect o.owner,o.OBJECT_TYPE, substr(o.OBJECT_NAME,1,20) objname , b.objd , b.status,
count(b.objd) from v$bh b,dba_objects o where b.objd = o.data_object_id
where owner='BISTG' group by o.owner,o.object_type,o.object_name,b.objd, b.status ;The result are identical before and after. have the buffer cache really been cleared?

That's a bit of documenation that is about 10 years out of date - RAC isn't supposed to "ping" (although it does) it's supposed to use "cache fusion". A "ping" is the term Oracle uses to label the action of one instance writing a block to disc for another to read. The modern term is "fusion write".
1) Is v$BH not good for single instance, since it is a Real Application Clusters view? I did see the view in non-RAC and query it returning lots of rows. Are the result meaningfulv$bh is not relevant to just RAC systems, it is an outer join between x$bh (the buffer headers - which are always relevant) and x$le (the lock elements - which are relevant only to RAC) - being an outer join it supplies information that can be used in single instance.
2) The phrase in Oracle Doc is hard to understand as usual. Does 'number of pings for every buffer' means those buffer cache blocks that are pinned in SGA, or just every block of buffer cache?
See above - but I don't think I'd look at v$bh (even in a RAC system) for pings and false pings without first checking whether Oracle has fixed the code that reports them.
I used ALTER SYSTEM FLUSH SHARED_POOL to clear buffer cache in a single instance, and check buffer cache before and after the clearing buffer with queryselect o.owner,o.OBJECT_TYPE, substr(o.OBJECT_NAME,1,20) objname , b.objd , b.status,
count(b.objd) from v$bh b,dba_objects o where b.objd = o.data_object_id
where owner='BISTG' group by o.owner,o.object_type,o.object_name,b.objd, b.status ;The result are identical before and after. have the buffer cache really been cleared?I hope you meant: alter system flush buffer_cache; but even if you did the numbers wouldn't change. "Flushing" the bufer cache doesn't really empty out the memory, it simply relinks the buffer headers to a different list, and sets the status to "free". Amongst other things that means it leaves the objd in place.

How to configure multiple buffers and execute them sequentially?

I would like to build up a path follower using at least two buffers. I wish to write data into the buffers in advance and then execute them sequentially. How can I do?
I have tried the case for using two buffers, and could only get the two buffers to work "sequentially",
which means that I could first write data into buffer 1, then execute it, then write data to buffer 2,
then execute it. Is there any way that I could use multiple buffers and exectue them as the sequence as
I want?
The following are the steps that I used for dual buffers:
buffer 1:
flex_set_op_mode
flex_configure_buffer
flex_write_buffer (check ready)
flex_start (check complete)
buffer 2:
flex_set_op_m
ode
flex_configure_buffer
flex_write_buffer (check ready)
flex_start (check complete)
I wish to achieve the following:
flex_configure_buffer (buffer 1 & 2)
flex_write_buffer (to buffer 1)
flex_start (buffer 1)
while waiting (flex_write_buffer (to buffer 2))
flex_start (buffer 2)
The purpose of my using two buffers is to try to prepare data for buffer 2 when we are waiting
for the execution of buffer 1 and we could execute buffer 2 almost immediately when buffer 1 was
done. Apparently, I have tried and with no luck to get it to work.

You can always configure a buffer for indefinite continuous operation by setting the total points value in the configure buffer function to be the maximum value allowed. You can the use the check buffer function inside the while loop to monitor the backlog of your buffer in order for enough positions to be avaliable for the next set of points to be downloaded. As long as your sets of data are of a smaller size than the total buffer size this will have the effect you are desiring. You can always make your precalculations for the next set of points while the previous move is being executed, you just need to allow enough time between the beginning and the end of your first move for the next calculation to be done.

Read-Only Access to Specific SAP tables

Is it possible to grant a user read-only access to a specific table or tables?
For example, say I wanted to give someone SE16N capability for just EKKO/EKPO/EKBE and NO OTHER tables. Is this possible? How?
Thanks.

Hi,
as it was mentioned the transaction SE16N checks for authorization object S_TABU_DIS. The problem in your case is that the tables EKKO, EKPO and EKBE are already assigned to the authorization group MA - MM Appl. table. But there are many more tables assigned to this group. Changing assignment of standard tables is not a good idea.
Cheers

How to find out who deleted the standard table enteries

Hi,
Somebody has deleted entire KNA1 in one of our systems. Is there any way to find out who deleted the entries?
Thanks & Regards,
Kumaran Duraiswamy.

Hi
Look for help from an ABAPer. Go to SE11 for KNA1, use 'where-used list (ctrlshiftF3) and search for report that begin with Z* or Y* (perhaps LZ* or LY*, ie: function modules). See the ABAP coding if there is any instructions type:
DELETE kna1 FROM xxx.
Check too if the option &SAP_EDIT in tcode SE16N works in your system (see SAP Note 1420281 - CO-OM tools: SE16N: Deactivating &SAP_EDIT for instance)
I hope this helps you
Regards
Eduardo
PD: I forgot it, if option &SAP_EDIT works in SE16N, check the tables SE16N_CD_DATA and SE16N_CD_KEY.

How do I set a breakpoint in my install method in order to identify the error?
I've tried changing my install method and making it look exactly like the sample wallet applications accompanying the javacard kit, but I'm still getting the same error? here else could be the possible source of the error?

Need to fill a new field in table EKKO

Hi all,
i created a new field (ZZCODE) in the table EKKO. Well, now i would like to fill this field when the user save his purchase order. Which user-exit or BADI can i use ?
I tried a lot but either i can't change the parameters values either the FM is not raise.
Thanks for help.

HI CECG,
Yesterday itself i tried this example,
i will forward u the document to ur mail id,
plz provide me the mail id so that i will forward u the doc..
STEP-BY-STEP PROCEDURE FOR SCREEN EXIT IN ME21n TRANSACTION
Introduction:
                    SAP provides standard transactions to enter data into database. But a client may want to maintain some additional information in SAP other than what is provided.
                    To make provisions for this, additional screens have to be provided and additional fields must be added into appropriate database table.
Requirement:
                     You have to add the custom field in SAP standard table EKKO. Then we have to place the field in ME21N screen. When user enters any input into the field it should get updated in the database.
Note:
                     EKKO table is meant for Purchasing document header, you should add the field in the header level for ME21n screen. There you are provided with customer sub screens where you can add the field in the screen.
In EKKO table
include : cl_ekkodb
in that u can add the field u want
Procedure:
1.     You have to create a field in the Custom Include of standard table, after creating activate it.
2.     Double click on the include then you can add your custom field here.
Find out the Required Enhancements:
1.     Go to SMOD. Press F4 in the Enhancement field. In the next popup window, click pushbutton Information system.
MM06E005 : CUSTOMER FIELDS IN PURCHASING DOCUMENT
2.     Then mention the particular package name of the transaction you need to      enhance. Then you will be shown the list of Enhancement components for that particular package.
3.     Note down the enhancements. Then, come to the initial screen of SMOD and view the documentation of each enhancement to find out which one is required for your development.
MM06E005 is the Enhancement component we are using here.
Development
Creating a Project to include the enhancement:
1.     Go to transaction CMOD and create a project.
2.     Enter a description for the project.
3.     Then, click on the pushbutton Enhancement Assignments in the Application Toolbar.
4.     Click on the components in Application Toolbar.
5.     Here you will be shown the function module exits, screen exits and Include tables.
6.     Click on the custom screen SAPLXMO6 0101 in which it suits the requirement of adding the custom field to the layout.
7.     Click on layout and go to get from dictionary and select the field you need to add and click ok.
8.     Place the field in the layout and activate it.
9.     After that you come back and check the respective function module in which you need to implement the code. So, we need to import the data from sub screen for purchasing document header. Therefore we have chosen the EXIT_SAPMM06E_008.
10. Write code in the Function Exits to synchronize the programs:
                       Now, code has to be written in the function modules EXIT_SAPMM06E_008 so that data flows to and fro between the main SAP program and custom sub screen program. Double clicking on the exit we get the following screen.
11. Double click on the include and write the required code inside it. Then activate it.
12. Now come back and activate the entire project.
13. Now go to ME21n transaction and create a purchase order by giving all the mandatory fields including custom field we have created. Go to SE16n, check whether the field got updated in the database or not.
Finally it gets updated in the database.
IF U PROVIDE ME UR MAILID I CAN SEND U THE DOCUMENT WHICH IS VERY CLEAR FOR PURCHASE ORDER
PLZ REWARDS POINTS IF HELPFUL,
Ganesh.

Number range for object MDTB does not exist - Message no. 61501

Hi All ,
I have done the necessary configurations in PP say
Order Type
Order Type Dependent Parameters
Scheduling parameters for planned & production order
Confirmation parameters
Availabilty check etc
and iam able to create planned & production order and confirma the production order.
I want to configure for MRP: -
Settings done are
Have activeted planning file entry for all plants.
When i run MRP system throws a error Number range for object MDTB does not exist - Message no.61501 
Is there anything to do with plant parameters OPPQ and Mrp Group OPPR.
I just tried plant parameters,standard 0001 is not available for copying.
Suggest me how to proceed to set MRP.
Shankar

Hi shankar
it is a good practice while creating the plant copying the plant from the standard plant so that all the standard table enteries will be copied for the plant as the standard plant is not there youcan think of copying from any other plant similar to your plant which has the required entry. else
in SE16N check the NRIV table for the Object MDTB. if enteris found then make the table entry with the help of abaper.
hope this helps
regards
SK

Se16n check buffer.
