Input/Data Stream Help
I have a program that outputs text. I want to modify it to use a data
stream that can be read by another program. How do I go about this?
Are there any online guides where I can learn this? I have looked
around, but haven't found anything useful as of yet.
Thanks for any responses.

I have a program that outputs text. I want to modify

go about this?Not at all. Using a data stream for text is a most inappropriate choice. Use print streams or buffered readers/writers.
Are there any online guides where I can learn this? Yes, it's called the API. It e.g. tells you what a DataOutputStream is good for.

I have a input data(.txt) in form of:
0. 12,45,23
1. 23,10,15,21
2. 15,32,25
3. 1,25,36
how can I get the input stream such as
for(i=2;i<=10;i++){
for(j=0;j<i;j++){
every line of input file that (the column_index mod i) =j
for example i=2 j=0
then i get the 0th and 2th column of input file
i=2 j=1
then i get the 1th and 3th column of input file
Thx for help very muchReview

Hi,
I have a process with a reader of master data that outputs 5 records that feeds simultaneously into 3 different lookup and return processors.
Each lookup and return processor brings some data back from a detail table. There can be multiple details so I follow each lookup processor with a split records from array processor. Hence I end up with 3 'streams' of data. Stream 1 has 8 records, stream 2 has 5 records and stream 3 has 6 records.
I join all these streams to a Merge Data Streams processor.
I end up with 9 records so although the help for the Merge Data Streams processor says 'Merge Data Streams does not perform any transformation, matching, or merging of records' there is clearly some merging going on.
What is the behaviour of the merge data streams processor in this scenario?
I have added attributes and flags into each of the streams. How many records should I see and what values should the added attributes/flags have (some records show attributes/flags from all 3 streams whereas others show just those attributes/flags from one stream).
I have developed a test case simply to understand what the processor is doing but it's not obvious and furthermore it's probably unwise to develop EDQ processes where the processor behaviour is not documented and guaranteed to remain consistent. What I am trying to achieve is to bring all of a person's (the master data) various details (assignments, employers, etc.) together so we can check the data (some rules require data from multiple details).
Thanks, NikCheers Mike - and for the explanation of the terms.
I think I understand now how it's supposed to work.
What I'm finding however is that when I set a flag to Y at the beginning of a path (that includes a lookup and return and then split records from array processor) that flag is showing no (i.e. an empty) value in SOME of the records shown in the subsequent MDS processor (it's fine the very last split processor before we get to the MDS but then again there are fewer records in that split processor than the MDS).
In my case there are obviously more records in the MDS processor than there were in the original reader (because the lookup and returns are configured to have unlimited maximum matches). As mentioned, the different paths return different numbers of records before being combined in the MDS. Say a reader has 5 records and path 1 returns 8 records in total including a path-specific flag (flag1, set to Y) but path 2 (that again adds its own path-specific flag (flag2, set to Y) returns just 5 records (since nothing was added from the lookups) are you saying that flag2 would show as 'Y' for all 8 records shown in the MDS?
Hopefully you would be able to see what I mean if you try to create a process like the one I've described (or I can upload a package).
Re. the purpose of the separate paths approach it is simply to allow the visualisation ('showing the working' as Neil puts it) of the different checks being carried out by the process.
This is considered one of the benefits of the tool over writing SQL queries (with outer joins, query criteria, etc.).
Also, as mentioned I was following an example that Neil put together for us to ensure that we are doing things in a 'proper' and supported way.
If we put all the lookups, etc. for all the checks into one datastream then it no longer becomes so understandable and the value of joining processors in a process over simply writing SQL becomes questionable; arguably the EDQ process in fact becomes less easy to understand than simply writing SQL.
Also, to go down this route I will need to revise the (what was previously substantially working until I revised it) processes that I have already developed.
Thanks, Nik -
Need help in triggering the Data stream load using process chain
Hi Guru's
is it possible to trigger a data stream load using process chain?
Any help is highly appreciated.
Thanks
IndiranHi Indiran and welcome aboard!
Don't think this is possible. SAP BW & SAP SEM-BCS are rather independent systems. Though, BCS lives on top of BI-BW stack, it even may have master data different from those in BW.
Process chains, AFAIK, is completely the BW's feature. Certainly, you may use PCc on BW side, loading ODS/DSO and cubes involved in BCS data model.
The main con here is the lost transparency -- you don't control everything from the consolidation monitor.
The pro side is also rather obvious for me. Since, very often there is a huge difference between data quality at the data source and in the BCS totals cube, I need to make a lot of data transformation. Not only some data calculations or cleaning, but also transformation of data model: key figure model -> account model. It's much more easier to do in BW, for me.
I even call the ODS/cubes/routines involved in such transformation as intermediate layer, the layer between data source and SEM-BCS.
And this layer lives rather independently from BCS.
Hope this helps. -
I am a new MacBook Pro owner. I have Microsoft Office: Mac2011 I downloaded a document from Sharepoint. I clicked on the document to open it.....I then clicked on Enable Macro and the document opens, but will not allow me to input data. Thank for any help.
Hey TobynJ:
Sharepoint will use your network username or password if it is setup that way, but I'm not talking talking about that. I am talking about permissions to be able to write to the document, you might only have read rights and not write. -

Problems Reading SSL server socket data stream using readByte()
Hi I'm trying to read an SSL server socket stream using readByte(). I need to use readByte() because my program acts an LDAP proxy (receives LDAP messages from an LDAP client then passes them onto an actual LDAP server. It works fine with normal LDAP data streams but once an SSL data stream is introduced, readByte just hangs! Here is my code.....
help!!! anyone?... anyone?
1. SSL Socket is first read into " InputStream input"
public void run()
Authorization auth = new Authorization();
try {
InputStream input = client.getInputStream();
while (true)
{ StandLdapCommand command;
try
command = new StandLdapCommand(input);
Authorization t = command.get_auth();
if (t != null )
auth = t;
catch( SocketException e )
{ // If socket error, drop the connection
Message.Info( "Client connection closed: " + e );
close( e );
break;
catch( EOFException e )
{ // If socket error, drop the connection
Message.Info( "Client connection close: " + e );
close( e );
break;
catch( Exception e )
//Way too many of these to trace them!
Message.Error( "Command not processed due to exception");
close( e );
break;
//continue;
processor.processBefore(auth, command);
try
Thread.sleep(40); //yield to other threads
catch(InterruptedException ie) {}
catch (Exception e)
close(e);
2 Then data is sent to an intermediate function
from this statement in the function above: command = new StandLdapCommand(input);
public StandLdapCommand(InputStream in) throws IOException
message = LDAPMessage.receive(in);
analyze();
Then finally, the read function where it hangs at "int tag = (int)din.readByte(); "
public static LDAPMessage receive(InputStream is) throws IOException
* LDAP Message Format =
* 1. LBER_SEQUENCE -- 1 byte
* 2. Length -- variable length = 3 + 4 + 5 ....
* 3. ID -- variable length
* 4. LDAP_REQ_msg -- 1 byte
* 5. Message specific structure -- variable length
DataInputStream din = new DataInputStream(is);
int tag = public static LDAPMessage receive(InputStream is) throws IOException
* LDAP Message Format =
* 1. LBER_SEQUENCE -- 1 byte
* 2. Length -- variable length = 3 + 4 + 5 ....
* 3. ID -- variable length
* 4. LDAP_REQ_msg -- 1 byte
* 5. Message specific structure -- variable length
DataInputStream din = new DataInputStream(is);
int tag = (int)din.readByte(); // sequence tag// sequence tag
...I suspect you are actually getting an Exception and not tracing the cause properly and then doing a sleep and then getting another Exception. Never ever catch an exception without tracing what it actually is somewhere.
Also I don't know what the sleep is supposed to be for. You will block in readByte() until something comes in, and that should be enough yielding for anybody. The sleep is just literally a waste of time. -
Hi! All.
I am facing an issue in Data Stream upload.....The Target field 0Company is 6 char. and the source field 0Company code is 4 char. in length....the system gives an error ...the value Target field exceeds source field..use info object with greater length.....however, upon mapping Company to another infoobject...with 6 char..used instead of 0comp-Code...the system returns yet
another error that its not coming from source system or source system can't be determined i.e. the new info object.......
I was thinking changing target field length to four...any work around this issue...If the target field is changed i.e. 0company what implications will it have or just changing the field in data model do the trick??
Thanks for your input....
VictorHello Viktor,
If i understood well your problem i faced the same thing in the past.
When costumizing the load from data stream include the lenght to 4 characters or try to include an offset of 2.
Hope is helps.
If yes award points.

How do you separate UDP data streams
Hi. I'm currently using LabVIEW 2013 to read in a UDP data stream (packet) that contains various parameters. I am successful in receiving the UDP packet using the UDP Open and UDP Read vi. On the data out of the UDP Read I have it running into the "Unflatten to String" function and the type I have created a cluster containing 32-bit floating point (Single Precision in LabVIEW) numeric constant, since that is the type of data I am receiving. To be able to separate the different parameters coming in, I have created the same number of numeric constants blocks to equal the number of parameters. Is there an easier way to separate the data from the UDP data out so that I don't have to create so many numeric constants to represent the same number of data I have coming in? Sometimes we will way more than what is listed below.
Any help will be appreciated. Thank you in advanced
Attachments:
Example layout (Not actual).vi 11 KBIf all the data is the same type, then you can wire an array as the datatype instead of a cluster. Set the "data includes array or string size" input to False (the default is True). The output will be an array, and you can index out the values you want.

How to input data into a table with columns?
I am trying to input data into a table. My table have 5 columns and an unlimited amount of rows. I created a program in LabView that enters the data into the table but it enters all of the data in one row. I would like to enter the first set of information into the first column, the second set of info into the second column and so on. I am including a copy of the program that I am working with. I would like the number of runs to be put into the first column (it should count down like number 5 in first row, number 4 in second row, number 3 in third row, and so on). I would like the applied voltage to be placed in the second column, and so on. Any help or information will be greatly appreciated. I am working with LabView Version 6.1 and 8.0. I am submitting the vi from 6.1.
