Updation of higher level item text to lower level item text

Hi All,
while creating sales order VA01 i need to pass the value of higher level item text to lower level item text
for that i read the text of the higher level item text using the fm read_text
and pass the text to the lower level items using save_text and commit_text
this coding works only when the lower order item text is empty
my queries are
1. if the lower level item having some text that text will be replaced by the higher level item text, that is happening but showing error that I/O error , how to solve this
2. while gone to VA02 and add one more item then also same error is happening how to solve this please help me.

Copy higher level item texts to lower level items

Hi All ,
I want to copy the texts of the higher level items into lower level items
i created a logic how to copy the texts from higher level to lower level
but the problem is there are so many textid's in higher level items,
how to determine the all id's dynamically with out hard coding,
is there anytable exists to determine the text id's automatically depending on the salesorder and itemno
helpful answers will be rewarded fully
regards
krishna

Hi,
You have to go as below:
With Sales Order Item, you get Item Category i.e VBAP-PSTYV.
With Item Category, go to table TVAP to detemine field TXTGR i.e Text Determination Procedure
Now check table TTXERN with fields TDOBJECT = VBBP - Denotes Sales Order Item
and TXTGR retreived from TVAP. Retreive the results of TDID which are the text id's associated for that sales order item.
So the relation is VBAP -> TVAP -> TTXERN.
Check and let me know if you have any problem.
Kind Regards

Condition - filter at lower level than displayed

I have the following requirement to display data in a query. For the purpose of this example, the relevant characteristic are Plant and Delivery. The KFs are Volume & Revenue. I want to display by Plant the total volume and revenue without displaying delivery, but only where the total volume on the delivery is > 0. If I look at the data at the delivery level I would see the following.
Plant Deliv    Vol   Rev
A      1        100   50
A      2        200   75
A      3          0   25
When I run my query, I want to see the following. Delivery 3 is ignored.
Plant   Vol   Rev
A       200   125
I've played with conditions but can't make it work. any ideas?

Have you looked at using the precalculated value set or the resultset query? This will run the lower level query and then filter on the higher level query by the lower level values.

Is it a bug or just a typo in Agilent 532XX Series\Public\Data\Low Level\Fetch Measurement (Single).vi?

Hi, All
I am using Agilent 532XX Series driver to read data from a frequency counter. In the low level subVi : \Public\Data\Low Level\Fetch Measurement (Single).vi, "Scan From String" is used to convert the data.
however, if I check the error of this function, it always show me a error with current format string "%.;%g;". after I changed it to "%;%g", I don't get the error anymore.
If anyone use this funtion, please check the error out of that fuction and see what you get.
Regards
CQ

I don't have the instrument, so I can't reproduce it completely, but I've done some research and if there is an error I don't think it's in the string conversion itself. I say this because:
From what I can gather, a typical output string would be the following: +4.27150000E-03
I took just a "scan from string" node and gave it that string as a string input and %.;%g; as the format specifier string. This yielded a numeric value of 0.0042715
So, as far as actually finding the root of the problem, there could be a few things going on. My first thought is some form corruption causing the data received to not be valid for conversion. There are two ways of testing this:
Open up a test panel in MAX and perform a loopback test, as described here: http://www.ni.com/white-paper/3450/en/#toc4
-or-
Install and open NI IO Trace and view the bus traffic as detailed here: http://digital.ni.com/public.nsf/allkb/282C5D41E2BA04F2862574BA007803B9
If the loopback tests works properly, go ahead and run the IO trace and post the results here.

Low level code

hi
while configuring SNP planning run -SAPAPO/SNP01 screen under object selection >manual selection i could see planning version, product, location and low-level code....
1. what is the significance of this parameter low level code ?
2. how it reacts to the planning run ?
my guess is that it takes into account all the tail end level of the BOM that belongs to the product ..but am not sure ..since it is 000/production server i dont want to experiment
Please help me understand the science behind low level code,can you please suggest an easy to understand link or material
thanks

Hi Rahul,
The low level code the position of a particular location product in a supply chain. SNP heuristics use it to determine the correct planning sequence. This is particular important if you are running "Location Heuristics" and putting the location products in the selection and want system to plan for only those location products.
The system will use the low level code to determine which location product to plan first and then move to the next one and so on.
You can refer the following links for further explanation.

How to find first level WBS from Lower Level WBS

My client is posting cost at wbs which will be at level 5 or 6 and i need to find 1st level wbs for that 5 or 6 level wbs..
So Is there any Function module to find 1st level wbs from any lower levels...
or any suitable code?

Hi Sachin,
in table PRHI you have the relationship between a WBS element and its superior level WBS element.
For example:
Level 1: XYZ (internal code PSPNR: 00000001)
..Level 2: ABC (internal code PSPNR: 00000002)
..Level 2: DEF (internal code PSPNR: 00000003)
....Level 3: PQR (internal code PSPNR: 00000004)
...then in table PRHI you'll have:
PRHI-POSNR = 00000001 ... PRHI-UP = 00000000
PRHI-POSNR = 00000002 ... PRHI-UP = 00000001
PRHI-POSNR = 00000003 ... PRHI-UP = 00000001
PRHI-POSNR = 00000004 ... PRHI-UP = 00000002
...meaning:
WBS element XYZ is top level
WBS element ABC depends of WBS element XYZ
WBS element DEF depends of WBS element XYZ
WBS element PQR depends of WBS element DEF
Then you can iteratively (or recursively) "climb up" the structure of the project until the WBS element of level 1.
I hope this helps. Best regards,
Alvaro

Low level disk access using win API libraries

Hello All,
One of my project requires "low level access to the drives (usually pen Drive)' for analysis. I think this is possible using WIN API functions, i tried to read using kernal32.dll but i am unable to complete the task effectively, since i dont have sufficient exposure to text oriented languages. Basically i need to read the memory as it is stored, just like stream of bytes. Could any one guide me how do i proceed inorder to get rid of this.
thank you.

Unfortunately no. You cannot mix both high and low level on the same screen. You'll probably have to draw it out yourself and capture user input, unless you're willing to use textboxes.
Or.. i suppose you can try using customItems for all your "coloring" instead?

Example using low level API POI for generating Excel??

Hi
is anyone know good URL that teaches generating Excel using low level API using Apache POI?
The reason is because i want to set the password for either workbook/sheet in high level API but it cant be done.
the only thing can be done using High level API is protect sheet without password.
Any idea?
Thanks

There is quite a good pack of documentation that ships with HSSF. To answer your question, I have just gone to the how to page and copied the example below, hope it helps.

Can I use textfield in an application with low level api?

Hello !
I am developing a mobile application using the low level api.
I have to use it, because I do a lot of coloring.
But I want to use high level textfields as well. Is there any way
to include them in my application without using forms?
Does any one know, why J2ME designer's have limited the access
to the TextField's paint()-method? That's why I cannot inherit
from TextField and overwrite the paint() as I would like to do.
Thanks.

Unfortunately no. You cannot mix both high and low level on the same screen. You'll probably have to draw it out yourself and capture user input, unless you're willing to use textboxes.

Cumulation of lower level item prices to higher level items

Hi,
We have a specific requirement that we use high-level materials that is not relevant for pricing and lower level items connected to higher-level item that are RA and billing relevant. How do we modify the pricing procedure to cumulate (roll-up) the lower level items to higher level item which is not price relevant but statistical value should be updated at this level for billing purpose.
We want to achieve this using/modifying only pricing procedure and not via user exit..
Request SAP experts to provide some inputs to this issue..
BR/Rajasekhar

Hi rajsekhar
But generally if you want to transfer the cost of the sub item to main item then you can check the box Cumulative cost in copy control VTFL . But your requirement is quite opposite .So you need to go to assign a New Reqt / Alt calc type to the cond type , telling that the header item cost which is not relevant for pricing has to be transferred to sub item .So you need to integrate with the ABAP'er to give inputs to him and giving our requirement also

Low-Level or High-Level for GUI ?

I am developing a MIDLet that has to run CLDC-1.1 MIDP-2.0 Devices. The MIDLet has a simple user interface, and there is no gaming. I developed the MIDLet using the high-level GUI class, but I discovered that this class is nice, yet limited. Now I am investigating using the low level canvas class for the GUI. Is it possible to maintain cross-platform compatibility with the canvas, or should I stick with the high-level class?

High Level Group
Classes provided are
     Perfect for development of MIDlets that target the maximum number of devices
     Heavily abstracted to provide minimal control over their look and feel
     Classes do not provide exact control over their display
Low Level Group
Classes provided are
     Perfect for MIDlets where we want precise control over the location and display of the UI elements
     If more control there is comes less portability It may not be deployable on certain devices

High performance (low level) jdbc access routines

Does anyone know of any low level jdbc access routines?
My need is to be able to do high speed data access. I'm looking for something 2 orders of magnitude faster than what is available with the typical use of java.sql (connection, preparedstatement, resultset and so on).
Several years ago while using visual basic and odbc, I had to use direct calls to the odbc32.dll functions for data access to get the performance I wanted rather than the ado and rdo stuff. I am wondering what is available with jdbc - perhaps the routines that are used when writing jdbc drivers themselves. I don't know if there is an equivalent "gateway" that all jdbc drivers use (like the odbc32.dll that is used with all odbc drivers in windows)
Any comments would be appreciated. Even just hints as to where I might find this kind of information.

Does anyone know of any low level jdbc access routines? What are you expecting besides what is provided in the java.sql interfaces?
The JDBC spec spells out what the interfaces are. There isn't anything else to call.

I don't know if there is an equivalent "gateway"

Any comments would be appreciated. Even just hints
as to where I might find this kind of information.Sounds to me like you want to write your own driver, and when you're done it will only be good for one database and operating system.
I'd have to ask what made you so certain that database calls were the bottleneck in your app. For the typical Web app, a reasonably well written persistence layer will be fast enough. There's other network latency in the system, and UI response can be slow enough to keep up. Are you worried about high throughput to the database for a Web app? If so, you might be guilty of premature optimization.
Unless I was absolutely certain that the JDBC driver from my database vendor would not do the job, I'd write the app and then profile it to find out where the performance bottlenecks were. I wouldn't take this extreme step until I was certain that the driver was the problem and a custom version would fix it.

High level user and Low level user

Hi to all gurus,
How SAP diffrentiates between high level user and low level users?? I mean if the licences are for 25 high level user and 50 lowevel users, than how SAP will categorize the high level and low level user licenses?? Is there anyway where BASIS person has to specify??
Thanks and Regards,

Ask your SAP Account Manager, he will be happy to explain it for you.
