Start process -"Start using Metachain or API"

Dear Experts,
I have a process chain,PC2 that needs to be scheduled after completion of process chain, PC1. Now can I use the condition "Start using Metachain or API". But I have no idea how it works. I referred to documentation service.sap.com but they dont tell me much about this. Can somebody please tell me or refere me to some kind of documentation on how this condition works?
Thanks.

Hi Visu,
Make PC2 as a local chain in PC1. and use 'start using meta chian option' for PC2, so that PC2 will automatically trigger when ever the PC1 is completed.
Regards-
MM

Starting process chains using RSPC_API_CHAIN_START(parallel execution of processes)

Hi,
We've got sap bw 3.5 installed.
We are using API RSPC_API_CHAIN_START to start executing process chains.
IF we are using param I_SYNCHRONOUS = 'X' then if we have parallel processes in chains they are executing one by one.
IF we are setting param I_SYNCHRONOUS = '' then proccesses are executed in parallel. But I recieved all the prompts. For example for chosing background server.
and others.
Is there an opportunity to combine these 2 cases: not to have prompts and execute processes in parallel?
Thanks for you help
Andrey

Hi,
I tried without I_SYNCHRONOUS param, it works the same as I_SYNCHRONOUS = ''. I recieve all the promts.
Thanks for you help.

My Problem Is Process2 is initiated by some "Guest" User instead of processor of that action.

Powershell start-process argumentlist

I have an issue with powershell 4.0 where start-process converts my credentials from a type of System.Management.Automation.PSCredential to System.String. Use the following lines to replicate this:
$Credentials = Get-Credential
get-member -InputObject $Credentials
start-process C:\Windows\SysWOW64\WindowsPowerShell\v1.0\powershell.exe -ArgumentList "Get-Member -inputobject $Credentials | out-file C:\results.txt"
If you look at the results of the 1st get-member command, the type is System.Management.Automation.PSCredential. If you look at the results of the 2nd get-member command, the type is System.String. Does anyone know if this is intended behavior?
Is there a way around it?

I am using start-process to run a command which interfaces with VMware PowerCLI. One of the cmdlets of powercli is Set-OSCustomizationSpec. Set-OSCustomizationSpec has an argument that accepts PSCredentials, -DomainCredentials. When the
credentials are passed without start-process, the cmdlet succeeds. If I call it with start process, the cmdlet fails with the error
'Set-OSCustomizationSpec : Cannot bind parameter 'DomainCredentials'. Cannot convert the "System.Management.Automation.PSCredential" value of type "System.String" to type "System.Management.Automation.PSCredential"'
The actual command i am using is: "start-process powershell -argumentlist "<Add VMwareSnapins>;Set-OSCustomizationSpec <SPEC> -NamingScheme <Scheme> -NamingPrefix <Name> -DomainCredentials <Credentials>; new-vm..."
If you issue the command "get-member -inputobject $Credentials | out-file C:\results.txt" the type shows system.management.automation.pscredential. If you issue the exact same command with start-process(start-process powershell.exe -argumentlist
"get-member....) the type shows system.string.
The issue has nothing to do with piping to a text file. The original post was simply a demonstration of the error. I apologize for the initial lack of clarity.

Duplicate start process

We have a problem wherein our process chains are getitng triggered twice.
The chains are scheduled by event triggering and events are triggered thru dummy jobs.
WHen I rescheduling I get this warning message.
Several start processes with the same start condition as
START_ZZ have been found.
Should all these jobs be removed from new scheduling?
Is it possible to find what are the start processes with same condition?
The start condition is triggered by event in process chain.
Thanks in Advance,
Rajarathnam.S

Dear Ashish
Thanks for your help. I learned a new thing (table)
But still it didnt solve my problem...
I checked for the chains using the start process. But it shows only one chain..
Several start processes with the same start condition as
START_ZZ have been found.
This might mean the event used t o trigger the start process is used to trigger other start process also.
Is there anyway I can check the processes or jobs triggered by an event??

I assume here that your application is deployed on a different physical machine of where LCES is deployed and running.
Do the following test:
- Say that LCES is deployed on machine1 and your application is deployed on machine2. Ping machine1 from machine2 and note the ip address.
- Ping machine1 from machine1 and note the ip address.
The two pings should match.
- Ping machine2 from machine1 and note the ip address.
- Ping machine2 from machine2 and note the ip address.
The two pings should match.
Usually this kind of error would happen if your servers have internal and external ip addresses.

Is it possible to load a non-standard image using some Java API?

Hi,
My "problem" is:
1. I have an image called "mediterranean_sea.IMG" (non-standard image format)
2. I need to process it (histogram, palette, etc).
3. I'm wondering if it is possible to load this image an process it using some Java API.
4. I've tried to do this using JAI but I think that this API only works with TIFF, PNG, JPEG, etc.
Any idea?
Thanks in advance,
Roger

I have been able to open PDF docs using C# API Process.Start("Full_path_To_the_PDF_File") in windows 7 or windows 8 with all previous versions of Acrobat32 reader.

I have been able to open PDF docs using C# API Process.Start("Full_path_To_the_PDF_File") in windows 7 or windows 8 with all previous versions of Acrobat32 reader.
However, with v11.0, the same command, in Windows 8, it does not open the PDF document. I can see the Acrobat(32) started in the task manager, but the document does open. Not sure how I can troble shoot this problem. Any help would be appreciated.

I haven't use the C# API but I imagine it is the same as C ShellExecute. Which in turn is the same thing (in essence) as double clicking in Windows Explorer.
So... does Adobe Reader run normally on this machine?
And does it start and open if you double click on a PDF file?

Unable to open PDF files with Adobe Reader v11.0, in Windows 8, using C# Process.Start()

I have been able to open PDF docs using C# API Process.Start("Full_path_To_the_PDF_File")
in windows 7 or windows 8 with all previous versions of Acrobat32 reader.
However, with v11.0, the same command, in Windows 8,
does not open the PDF document. I can see the Acrobat(32) started in the task manager,
but the document does open. Not sure how I can troble shoot
this problem.
As a test, I created ta batch file, with a simple command that calls AcroRD32.exe with a PDF file as a parameter. When I executed the batch file in cmd window, it opens the PDF document. If I execute the batch file using Process.Start(), again it does not
work. The CMD window opens but, the document does not open. The cmd window just stays open.
So, there must be something with opening the PDF using the Process.start() command.
Any help would be appreciated.
Thank you,

This is something Adobe has to troubleshoot. Probably the pdf file association is broken. I suggest you to visit forums.adobe.com to ask Adobe about your problem.

Using CREATE PROCESS and START PROCESS in a JSP

Hi,
I have built a simple JSP page. I want to call my workflow program from this page.
How should I use the CREATE PROCESS() AND START PROCESS() inside the JSP page?
Also I want to get the value entered in the text field (which will be a hidden field) to be passed to the ITEM_ATTRIBUTE, which I have defined in my program. How can this be achieved?
Please give me the syntax for this.
Please find below the JSP page
=========================================================
<%@page import= "java.util.Date" %>
<script language="javascript" src="ibeCButton.js"> </script>
<html>
<head>
<title>First Page</title>
</head>
<body>
<H3>Today is:
<%= new java.util.Date() %>
<INPUT TYPE="text" NAME="CART_ID">
<INPUT TYPE="submit" onclick = >
</H3>
</body>
</html>
==========================================================
To use LAUNCHPROCESS in JSP, the following is the syntax.
public static boolean launchProcess
(WFContext wCtx,
String itemType,
String itemKey,
String process,
String userKey,
String owner)
Should WFContext have the connection information of the DB.
If I pass only the WFContext and itemType attributes are they enough? Please let me know.
Thanks

There are two options.
1. Good one.
Include wf*.jar files in your system CLASSPATH. Use oracle.apps.fnd.wf.engine.WFEngineAPI class to access engine APIs. You would need to pass WFContext for which you need WFDB.
You basically created WFDB with username, password and connect string. Pass it to WFContext and use it for all Workflow Engine APIs.
2. OK one.
You can get JDBC connection using the default mechanism that your custom Java and JSP code could be using. Call the PLSQL procedures WF_ENGINE.CreateProcess and WF_ENGINE.LaunchProcess over JDBC.
Anyways option 1 makes life easier.

Unable to start process via GP API in which group is exposed as input

Hi,
     I am not been able to start process using GP API for the particular senario.
I created Process at design time.
In this process I mapped parameters to a group and exposed this group, So that input is required for initiating the process.
Now I want to initiate this process via GP API.
I got sucess in starting processes which takes parameters as inputs or which does not need any inputs, but i was not been able to start process where group is exposed.
it's giving me GP INVOCATION Exception.
Please Help ASAP

3) is there any SDN help on MDM JAVA API with webdynpro for java? . can you please send the link on the same.
4) can you please help by providing sample code on how to use JAVA APIs for retrieving,deleting,inserting and Updating the data in the database.
if anybody helps on the same then it is the great help to me.
points are always rewardable...
Regards
Suresh babu

Hi Suresh,
You can have the MDM JAVA API javadocs from the link
http://help.sap.com/javadocs/MDM/SP06P2/index.html
There you can see a package named com.sap.mdm.examples.The classes in it contains some examples using which you can start understanding the code.
You need to have MDM JAR files for it. And these JAR files to be used at build time can be added to the project thru :-
Right click on project-> properties->Java Build Path - > Add external JARs
At run time you can add them the reference in
Right click on project-> properties->web dynpro references->library reference.
Thanks
