Conversation between 2 clients
Apologies if this is a stupid question, but my mind has gone completely blank!
I'm trying to write a program allowing 2 clients to connect to a server and exchange messages with one another. My problem is that I can't figure out how to allow the 2 clients to link up with each other once they've connected to the server.
I've been looking at examples, but they all seem to refer to chat room applications or multiple clients communicating with the server.
I'd really appreciate any thoughts on this,
Compassion
Two solutions :
1. One client provides his own hostname-port to the server that forward it to the client, then this client open this socket with an accept, and the second client connect himself to the first client. You have then a direct peer to peer connection. This solution is performent, but you might have firewall issues.
2. Your server accept the two client connections and, once the two client have asked to connect themself together, the server launch a thread that read on each connection and write directly everithing he read to the other connection.

3. With SE01, you can create a transport request for all table entries.
SE01 - Create button - Workbench request - Give description and save
Select the created request and click on Display object list.
Click on Display - Change button
Insert line button
ProgID: R3TR

Can I have a Face Time conversation between two Apple devices using the same Apple ID?
Can I have a Face Time conversation between two Apple devices using the same Apple ID?
Yes, you can, but the two devices can't have the same e mail address associated with both. Each, device needs its own unique e mail ADR. In your case, the iPod can call your iPhone if you use the phone number, but the iPhone can not call your iPod because it must use the e mail address, and if the email address is the same on both, the iPhone will think it's calling itself, so the call will not go through.

Can we share the same Business Action between clients?
Hi All,
I have a scenario wherein we have two Remote Trading Partners (say Remote1 and Remote2). Both these clients send EDI-850 documents and expect EDI-997.
So,
1. I first go to the Protocols Tab.
2. Create a Business Action (Process_850) and Follow the Wizard for the details.
In the process i create
a. Process Protocol
b. Document Protocol
c. Exchange Protocol
Now for the second client also sends us the EDI-850 document. So can I reuse all the above created objects and just have two Agreements one with Remote1 using the same Business Action (Process_850) but different Delivery Channels
Or should i be creating different Business Actions for the different Clients?
If i indeed have to create diff business actions then can i reuse the Document Protocol between clients? It does allow you to select and existing one.
Finally, If i understand this correct, We create a Business Action and hence the Document Protocol. We set the default values of the Document Protocol Parameters in here and when we create Trading Partners we override these (Application Sender Code, etc.). In a way we are saying that Process_850 is a business action that is processing 850 documents. 850 being a template and the document parameters are the replacements done on 850 when it is sent by Sender we have say Acme and when it is receiver we have GlobalChips.If it is for two diffrent trading partner you can share the same business action.

I am using TextLayout for rendering a unicode text.and calculated the bounding boxes of each characters in textlayout
. Font size is set as 12 and for the same Text i am also generating image of it and then i found out the bounding boxes for each characters with the help of already available tool.The tool chooses bottom -left as the image origin and calculate the coordinates based on that.Obviously these two coordinates will differ.Can any one please suggest a method for conversion between coordinates of textlayout and that of image coordinates mentioned above.I am using TextLayout for rendering a unicode text.and calculated the bounding boxes of each characters in textlayout

Precision loss - conversions between exact values and floating point values
Hi!
I read this in your SQL Reference manual, but I don't quite get it.
Conversions between exact numeric values (TT_TINYINT, TT_SMALLINT, TT_INTEGER, TT_BIGINT, NUMBER) and floating-point values (BINARY_FLOAT, BINARY_DOUBLE) can be inexact because the exact numeric values use decimal precision whereas the floating-point numbers use binary precision.
Could you please give two examples: one where a TT_TINYINT is converted to a BINARY_DOUBLE and one when a TT_BIGINT is converted into a DOUBLE, both cases give examples on lost precision? This would be very helpful.
Thanks!

What exactly is the diff between client dependant and client independant te
Hi gurus,
What is the diff between client independant and client dependant term.. I initially had a confusion related to client independant and client dependant Transport requests, where else are these words applicable, do they apply to data as well, if so how? any links to help me understand the difference..
regards,
kishoreHi Kishore,
Client Independant: These objects are not specific to any client. And it is universal which can be viewed,changed across the clients.
Client Dependant: These are the objects can be viewed, changed for the client for which it has been assigned. Other clients do not have access on these objects.
In SAP, all objects are finally stored as tables. "Mandt" is key field which determines whether the object is client dependant or not.
Client Independant transport requests will make the transported objects available across the clients. and Client dependent transport request make the objects available only for the client mentioned by field "Mandt"

Send Mail thru SAPMAIL in between clients?
Hi experts,
This time I want to know on how to send attachments text/xls files using SAP MAIL (SO01) in between clients? like clnt 200 to clnt 300? any FMs? BAPIs? RFCs?
Thanks & Regardsi think you got to run catproc.sql script and then see whether plsql.jar may appear in the directory.. also there is dbmsutilities script that might be helpful to you.. may not be the right solution but some trial and errors with those two packages will give you the anser for sure.

Difference Between "Client Level & Company Code Level"
Hello
Can any explain me the difference between client level and company code level?
What is the configuration that we do on client level and company code level?Message: Dear,
Client : Unit within SAP system, self-contained, separate master data with independent set of tables. It represent corporate group.

Note: You will do the configuration at company code level by logging into the client for master tables etc.. -
Difference between clients.
Hello all,
I have a basic question here.
What is the difference between clients in a system.
For example we are having 120, 600 and 700 clients in DEV
What type of data is stored in those clients. Will the data be different. Since programs are client independent can I do modifications to my programs in 600 and 700 clients.
Why the name SILVER and GOLD to the clients??
Please explain.Hi Naren,
Client strategies vary from place to place. But one thing to understand is that a client is SAP's way of logically seperating data. In the underlying database, though, it will be just one table holding all the data for all the clients within the same server.
There are repository objects and some configuration tables that are cross-client or client-independent. In the basis configuration, there is a setting where they configure each client to be modifiable, non-modifiable and if modifiable, whether client-dependent modification are allowed or client-independent modifications are allowed.
So, if they allow it, you can do your programs anywhere. But one more factor to consider is the transport layer. This is again configuration dependent on client. So if you are making changes in client that is not on the transport path, then you will have tough time getting it into higher systems.
GOLD, SILVER etc are typically terminology used for representing the importance of the client. Typically Golden client is one which is like a vault, where you move all your tested configuration and client-dependent activities and leave it there. This will only be used if there is a need for restore or creating a brand new client. All other clients in development system will either be constantly changing or refreshed periodically. There will be lot test data also. So you need a client that is clean from all this garbage and that is your golden client. I have to admit that I didn't hear SILVER being used anywhere, but it may be on similar lines.
Clients are dedicated to development, configuration, crash-and-burn, unit testing and golden client. It is not necessary to have all these, but most often they use this landscape in development systems.
In production systems, different clients are used to seggregate access and data.
Hope this helps,

Direct Connection between clients using sockets
Hi, I'm a new user and i have a problem with sockets:
The question is how can i directly connect two users that are already connected to a server in other machine???
I mean
user1 is connected to server
user2 is connected to server
user1 tries to communicate with user1 but don't want to use the server, and the server only provides the client1's ip
I first thought to do this:
user2 asks to server for the info of a client1-server waiting for connections, and i think it could work fine, but only if the ports are not closed by firewall, because client-server will be running in a transparent mode for user and user may not know anything about servers, sockets, ports, etc. the user only will work with a gui or something else and that's all
Does anybody know what can i do to make this possible???
PD
Sorry for my bad EnglishIt can be implemented like you said. Make one of the clients open a serversocket and pass the ip and port number through the server to the other client with information on where to connect.
If you're going to use direct connection between clients a lot then I would recommend that every client open a default serversocket at startup and register that information with the server and then every other client can ask the server for the ip and port to whatever client they wish to open a direct connection to.
Be aware that clients often are behind NATs and firewalls, so if need to deal with those issues you got to use hole punching (http://en.wikipedia.org/wiki/hole_punching) - pref on a known port like 80 - and to deal with the less frequently used application firewalls you can use http encapsulation in addition.
