Flat file header diferent from remaining file (function module GUI_UPLOAD)

Hello gurus,
I need to upload a flat file but the header is the control record with the number of lines in the file, and has a diferent structure from remaining file records.
I'm using GUI_UPLOAD in ASCII mode for the flat file and my first line with the control record does not "fit" the structure of the remaining records.
Whats the best way I read diferent line structures in the flat file so I can have a counter from the first line and all other lines in an internal table?
Using GUI_UPLOAD twice with diferent internal tables will have performance degraded...
regards.
Sérgio.

Hi,
Declare an itab as
ITAB TYPE STANDARD TABLE OF STRING
Variable for Tab limited
data :gc_con_tab TYPE c VALUE cl_abap_char_utilities=>horizontal_tab.
pass the control record to the internal table first then.
loop at it_final into wa_final.
concatenating gc_con_tab will add TABs in your output.
CONCATENATE wa_final-f1 wa_final-f2
into ITABl separated by gc_con_tab.
append ITAB.
endloop.
Then use GUI_DOWNLOAD to download ITAB.

Read an avi file using "Read from binary file" vi

My question is how to read an avi file using "Read from binary file" vi .
My objective is to create a series of small avi files by using IMAQ AVI write frame with mpeg-4 codec of 2 second long (so 40 frames in each file with 20 fps ) and then send them one by one so as to create a stream of video. The image are grabbed from USB camera. If I read those frames using IMAQ AVI read frame then compression advantage would be lost so I want to read the whole file itself.
I read the avi file using "Read from binary file" with unsigned 8 bit data format and then sent to remote end and save it and then display it, however it didnt work. I later found that if I read an image file using "Read from binary file" with unsigned 8 bit data format and save it in local computer itself , the format would be changed and it would be unrecognizable. Am I doing wrong by reading the file in unsined 8 bit integer format or should I have used any other data types.
I am using Labview 8.5 and Labview vision development module and vision acquisition module 8.5
Your help would be highly appreciated.
Thank you.
Solved!

Hello,
Check out the (full) help message for "write to binary file"
The "prepend array or string size" input defaults to true, so in your example the data written to the file will have array size information added at the beginning and your output file will be (four bytes) longer than your input file. Wire a False constant to "prepend array or string size" to prevent this happening.

Issue with use of Function Module GUI_UPLOAD

Hi Experts,
I have an issue in using the Function Module GUI_UPLOAD for uploading the contents of an Excel file on the Presentation Server to an internal table in an ABAP Program.
My file consists of around 300 records but the FM succeeds in uploading only the first 6 lines to the Internal Table specified while calling the FM.
I dont have any idea why this happens. Any pointers in this direction will be helpful.
Thanks in advance.

Why can't I run a powershell file I created from a powershell function

Ok so admittedly I am still learning a lot about powershell so this may have a very easy explanation/solution
So I have this script file and this is it in its entirety
function Add-DriveFunctions($Provider, $Path)
foreach ($Drive in $Provider.Drives)
if ((Get-Command | where Name -eq "$($Drive.Name):") -eq $null)
[String]"function $($Drive.Name):() {Set-Location $($Drive.Name):}" | Out-File $Path -Append
$Path = C:\Temp\test.ps1
"""Adding Drives""" | Out-File $Path
foreach ($Provider in Get-PSProvider)
Add-DriveFunctions -Provider $Provider -Path $Path
C:\Temp\test.ps1
When I run it it happily creates the ps1 file whose content looks like this
"Adding drives"
function Alias:() {Set-Location Alias:}
function Env:() {Set-Location Env:}
function Function:() {Set-Location Function:}
function HKLM:() {Set-Location HKLM:}
function HKCU:() {Set-Location HKCU:}
function Variable:() {Set-Location Variable:}
But the last line to actually load and run the ps1 file does nothing
even calling C:\Temp\test.ps1 does nothing
but if I load the file into ISE and run it from there
it works.
Unless I'm completely missing something I would think being able to call other ps1 files from other ps1 files or the command line would be a pretty important part of powershells flexibility.
So if anyone could tell me why in this case it does not work I would greatly appreciate that
Cheers,
Quidquid latine dictum sit, altum videtur

Ok i'm a little confused
in ISE if I write a ps1 file and i have just a function in it not anything calling that function when i run or debug it loads that functions definition into the current session and then from my console i can access my function. so Is that what the . is supposed
to do?
When i tried the . I get this
The term '.C:\Temp\test.ps1' is not recognized as the name of a cmdlet, function, script file, or operable
program. Check the spelling of the name, or if a path was included, verify that the path is correct and try
again.At C:\Users\rjs012978\Downloads\FunctionTest.ps1:20 char:1
+ .C:\Temp\test.ps1
+ ~~~~~~~~~~~~~~~~~
+ CategoryInfo : ObjectNotFound: (.C:\Temp\test.ps1:String) [], CommandNotFoundException
+ FullyQualifiedErrorId : CommandNotFoundException
Also I know i can do that with the mono letter drive but working on a network over half the alphabet is taken up by my actual network mapped drives.
And the provider i'm writing is connecting to multiple Space IDs that i'm making into my drives so I would quickly run out of letters.
proof of concept i know what i'm doing works if I do it manually
I know it's kind of silly but for me the amount of time i spend in powershell especially administering SCCM, the registry and AD being able to just type hklm: and hitting enter is a huge time save over the long haul than typing cd hklm: even though it's
just 3 more characters

How to open saved files using 'read from text file' function

Hi everyone, I am having a hard time trying to solve the this particular problem ( probably because I am a newb to lanbview ). Anyway , I am able to save the acquired waveforms by using the 'Write to text file' icon. I did manually modify the block diagram of the 'Write to text file' icon and create the correct number of connector so as to make my program work. But now I have no idea on how to modify the block diagram of the 'Read from text file' block diagram to make my program 'open' my saved waveforms. Or i do not have to modify anything from the block diagram of the 'Read from text file'? Can anyone teach/help me connect up? Do i need the build array on the "open" page?
Here are some screenshots on part of my program
let me know if you guys would need more information / screenshots thank you!

Ohmy, thanks altenbach. oh yeah i forgot about those sub VIs. will upload them now. Was rather demoralized after reading the comments and really struck me on how weak i'm at on labview really hope to get this done. But of course i have to study through and see how it works. Actually i am going to replace those 'signal generators sub vi' with ThoughtTechonology's sample code so i can obtain data waveforms real-time using Electrocardiography (ECG) ,Electromyography (EMG ) and Electroencephalography (EEG) hopefully i can find out how to connect the sample code.
( ps . cant connect it now unless my program is working otherwise labview will crash )
( p.s.s the encoder of my biofeedback trainer already acts as an DAQ so i wont need to place an DAQ assistant in my block diagram i suppose )
The sample code of ThoughtTechnology is named as attachment.ashx.vi. too bad i cant use it and present it as my project

Include text file and display from text file

Ok. I'm found the site with the monkey on the the flash thing and all it shows is a name, email and something else and I used it and it works by including a txt file and displaying text from that file as putting down this information
name.text = this.name;
and I can't find the site anymore to get help.
I want to know how to include a PHP script that shows this information like this
text=something I need&username=My Name&email=[email protected]
I want to show this stuff on the flash but every time I execute by using it as localhost/test.php, it will show a sentax error.
This is really stressing me out and I need a lot of help on this stuff.
Can someone help me?

ok. let me describe something else.
there's 3 text boxes that is dynamic text.
one of them is called name
the other one is called email
and last one is called location
in the text file, it shows this for importing to the flash file
name=My Name&email=EMAIL&location=My Location
When viewing the flash file that you created, it shows the name, it shows the email, and it shows location.
When I do it on my own even with a text file, it keeps on saying that there is an error on line 1.
I found a site that shows how to do it and it shows what to put in a text file, and it shows the action script. On the FLA file that he shows me has a monkey on the flash file and it has 3 text boxes that I described above. As well as the text file, it is the same. I used the example and it worked but I can't find the example again. I don't know what happened to the website and I don't know what happened to the download I had but it is not downloaded any more. I have adanced systemcare pro so it clears out my recent web searches and my recent downloads so I can't find it. I did a google search on anything about action scripts. I even did a monkey action script search and I couldn't find it.
It's making me mad and I don't know what to do. This is stressing me out way more than you think.
UPDATE:
I did a google search on a file I found in my www folder and I found it. finally.
Here's the site.
http://www.kirupa.com/developer/mx/externaldata.htm
now, I need to figure out how to load it from a PHP file.

How to run .ksh file in unix from .jsp files

Hi frnd,
How to connect unix servers from .jsp file & I want to run unix scripts .ksh files from .jsp files
Thanku
bhupathipawan

It is usually a bad idea to do any major processing directly within a JSP. It is better to create a helper class and invoke methods on that. This helper class can then be tested outside of the inhospitable JSP environment.
To run the '.ksh' file you will need to use either Runtime.exec() or the more modern ProcessBuilder. You will save yourself a lot of grief if you read thoroughly the 4 sections of http://www.javaworld.com/javaworld/jw-12-2000/jw-1229-traps.html and then implement the recommendations.
Note - although the 'traps' article is written around the use of Runtime.exec(), it's content is equally applicable to ProcessBuilder.

How can i get currency values from flatfile to function module

Dear All,
           I have to take currency values from flat file and i have to assign those flat file value to function module .
Eg: "Convert_to_local_currency". I need technical code how to calculate those amount in work area and how to assign those amount value function module.
          I need sample program for currency conversion from flat file to function module. My requirement is based on flat file amount i have to calculate in work area and assign those work area to function module.
With Regards,
Baskaran

Hi Satish or Baskaran,
First conform in which format the flat file is present, as abhi mentioned if it is there in notepad
try to use F.M GUI_UPLOAD as shown below...
CALL FUNCTION 'GUI_UPLOAD'
EXPORTING
FILENAME = 'C:\Desktop\rpf1.TXT'
TABLES
DATA_TAB = ITAB.
Now loop at ITAB Into Work_area and press the respect currency fields which you want and in the same way
if the file is in EXCEL format use F.M ALSM_EXCEL_TO_INTERNAL_TABLE
CALL FUNCTION 'ALSM_EXCEL_TO_INTERNAL_TABLE'
    EXPORTING
      filename = P_FNAME
      i_begin_col = 1
      i_begin_row = 1
    TABLES
      intern = ITAB
LOOP AT ITAB INTO WA.
CALL FUNCTION 'CONVERT_TO_LOCAL_CURRENCY'
        EXPORTING
          foreign_currency = wa-waers
          local_currency   = wa-waers
           IMPORTING
          local_amount     = tvals-gross.
    ENDIF.
endloop.
And as mentioned loop the records into work area and process the currenct field which is present in the
ITAB according to its field name. And make sure within the loop you call your function module.

but it shd give,
00010
00020
00140..
pls help with the code.
Edited by: Matt on Jul 9, 2009 7:49 AM

HI,
You are bound to get the last record because you are writing after the loop.
data ITAB_KOMV LIKE KOMV OCCURS 1 WITH HEADER LINE.
PERFORM GET_ITEM_DETAILS.
loop at itab_komv.
write :/ itab_komv-kposn, itab_komv-KSCHL, itab_komv-kwert.
endloop.
FORM GET_ITEM_DETAILS.
SELECT EBELN
EBELP
EMATN
TXZ01 "specification ----EKPO--TXZ01
BANFN
ANFNR
WERKS
MEINS
MENGE
NETPR
MWSKZ "tax code
PSTYP
ADRNR
FROM EKPO
INTO CORRESPONDING FIELDS OF
ITAB_EKPO WHERE EBELN EQ PO_NUMBER.
***tax calulattions
CALL FUNCTION 'ZMM_CALCULATE_TAX_ITEM'
EXPORTING
P_EBELN = itab_ekpo-ebeln
P_EBELP = itab_ekpo-ebelp
TABLES
it_komv2 = itab_komv.
append itab_ekpo.
* basically your write statement should be here
*loop at itab_komv.
*write :/ itab_komv-kposn, itab_komv-KSCHL, itab_komv-kwert.
*endloop.
endselect.
So that with every loop pass of the select statement the conditions are printed for every line item.
What i pointed out to you is the mistake which you are doing.
But the solution is not the correct one.
Within SELECT-ENDSELECT you should never code anything so as to avoid performance problems.
First try to get all data from EKPO into an internal table for the PO.
Do as follows
SELECT EBELN
EBELP
EMATN
TXZ01 "specification ----EKPO--TXZ01
BANFN
ANFNR
WERKS
MEINS
MENGE
NETPR
MWSKZ "tax code
PSTYP
ADRNR
FROM EKPO
INTO CORRESPONDING FIELDS OF TABLE
ITAB_EKPO WHERE EBELN EQ PO_NUMBER.
loop at itab_po.
refresh : itab_komv.
CALL FUNCTION 'ZMM_CALCULATE_TAX_ITEM'
EXPORTING
P_EBELN = itab_ekpo-ebeln
P_EBELP = itab_ekpo-ebelp
TABLES
it_komv2 = itab_komv.
loop at itab_komv.
write :/ itab_komv-kposn, itab_komv-KSCHL, itab_komv-kwert.
endloop.
endloop.
I hope you get my point.

Call WDA from ABAP via function module

Hi WDA experts,
is there any possibility to call a WDA within a ABAP report AND include it in the process.
The best would be to call a WDA via a function module - make some inputs on the WDA side - press submit and the function module gives me the data from the webdynpro back to my application.
I know that I can call a WDA via the function CALL_BROWSER, but in this case the WDA application is fully independent from the report and I am not able to post any data back to the report.
I also know FM WDY_EXECUTE_IN_PLACE, but in this case I need a HTML container to display the WDA and there it seems that I also never get back any data back to the report.
Any hints are appreciated.

Not too hard:
CALL WDA passing in a KEY on start plug.
write the data to a shared memory object using the key passed as the
key to a shared memort object on the submit.
(see blogs on writing Shared maemory objects in ABAP)
Then simply exit APP.
On return read the data from the Shared memory Object.
The shared memory object lives across the 2 sessions.
cheers
Phil.

How to exit from an update Function Module

Hi Friends,
I am using an Update Function Module in my program.The Program also has various other logics implemented in it. The Update Function Module gets triggered only when it finds COMMIT WORK statement. Now, I want that when the FM gets triggered and inside it, sy-subrc <> 0 at any stage, it should exit the complete processing and come to my main screen.
I tried to use Exit, STOP commands in the FM, but they only make the processing to exit from the FM.
Please suggest what shud I do.
Helpful suggestions will be surely rewarded.
Thanks in advance.
Regards,
Himanshu

hi hemansu,
after coming out from function module check value of sy-subrc
and
if sy-subrc ne 0
exit. or leave to screen 0 [module pool progarm] or stop.
endif.
if helpful reward some points.
with regards,

How to get structure from Idoc using function module?

Hi all,
I am looking for a function module in order to get the structure of a message type used for iDoc. The aim is to get the data element from the different fields in order to check authority if the data element is BUKRS.
Thanks for your help!
David

Hi David,
You can use the FM "IDOC_TYPE_COMPLETE_READ" which will get you the complete details of the IDOC type along with data elements referred for each fields in the segments.
The aim is to get the data element from the different fields in order to check authority if the data element is BUKRS.
Not sure if i understood the above requirement, if you could provide more info on the requirement, i guess you might get better a better solution from the forum. As there are other data elements with different names for company code (just look up *BUKRS* in SE11 under Data Elements to see what i mean), not sure if you can cover it all.

Chen

How to access Business object type attribute from a method/function modul ?

Hello,
i have created a business object type object along with attributes and methods. Now inside the method i want to access the attributes. inside the method i am writing:
data a type XXX.
a = me->attribute
this is creating a compilation error.
Now the method is defined as a function module in some package, so can anyone inform me how to access object attributes from the function module ?
pointes are awarded
Regards

Hello,
thanks for your answer, but this too did not work, "=>" is for static attributes and the attributes i have are not static. Moreover, i tried it but it gave the same error :
the abap error was when i was checking the code is :
the type me=>documenttype is unknown
as you know in SWO1 i created an object and when i create a method you link it to a function module and this is where you have the implementation of the method, so from this method how can i access the attributes on the main object that i created in SWO1
