Bind Parameters Process Flow ...

Hi,
Require to create a Process Flow through OMB+, and then bind some parameters for transformation to paramters defined against Start activity.
The Process Flow creation is complete, but am not finding a way to bind the parameters. Can anybody share the code.
Documentation is not very helpful.

Aha! It was the Parameters I hadn't got figured out.
Thanks a lot!

Creating variables in Process Flows and using thse variables in the filter

Hi,
I am new to OWB and in learing stage. Need to information.
*1. as to how pass/create/use variables to OWB mapping ?*
*2. Creating variables in Process Flows and using thse variables in the filter operator of the OWB mapping?*
*3. Other mechanisms of how to create/use variables within OWB mapping itself ?*
can you please provide the above details and guide me / help me in this regard.
Thanks,
skms.

1. Add parameters to your mapping using the MAPPING INPUT PARAMETER from the pallette.
2. Add parameters to the START operator in the process flow. Bind the process flow parameter to the Mapping parameter.
3. May be appropriate to use CONSTANTS instead of parameters.

Mapping parameters binding gets removed in process flow

Hi All,
whenever i import a mdl file from development to production
parameters binding of few mappings and pprocedures in process flow get removed automatically.
for example Map1 in PF1 has input parameter p1 binding set to Pf.p1.
this binding is getting automatically removed when i import the mdl file from development to production.
I am in big trouble bcz of it.
could anyone plz help.
Thanks in anticipation,
RD_RBS

This also happend to us when we moved from dev to prod. We really didn't find any good way to bypass this but just rather enter the binding values again manually. You might wanna check a few other things that got lost during the move. Such as DB Link(DB Connections on stage tables) and Outgoing Transitions in the process flows.

Process Flow Parameter Binding.

The docs on using process flow parameters are a bit sparse, so I wonder if anyone else has some input.
We kick off our ETL processes by an external enterprise scheduling tool due to several remote dependencies. This tool provides us with an audit id that we want to tag all of our current rows loaded with. Now, creating input parameters on the mappings is easy, but the docs seem to indicate that a parameter passed into a process flow can only be bound to one location. Given that our process includes a few hundred mappings, this would require the input parameter be input several hunderd times with each instance bound to a single mapping. That is not a maintainable option. Similarly, any documentation on passing OUT parameters from mappings to subsequent mappings seems entirely absent, so I'm not sure if I can "daisy chain" passing this parameter along.
Which, at this point, leaves me with passing in the variable to the process flow, having the first step be a SQL call that saves this ID to a table, and then having each mapping query this table for the audit ID in a pre-mapping procedure to use to tag the rows. The Process Flow will also have to have a closing SQL script to clear the audit id out of the table.
Is this my best option? Or does anyone have a better idea?
Thanks,
Mike

In 9.2, parameters were added by way of the property sheet for the Start activity.
In 10.2 what you do is, in the Explorer portion (the top section) of the palette you select the "Start" activity. If you then look at the top bar of the Explorer portion of the palette you will note that the leftmost icon (a green plus sign over a folder) is enabled. This is the Create button which, when pressed, will create an input parameter to the process flow. This paramter may then be used as a bind variable by other activities in the process flow.
Cheers,
Mike

Passing parameters from mapping to mapping with in process flows

I am new to OWB and i would appreciate if any one can suggest me on how to solve the issue i have.
I am trying to pass a parameter from one mapping to another mapping.
ex: key need to be passed
start ----->A--->B--->C----->END
B needs to pass the key to mapping C
In B i have mapping Out put parameter and in C i have a mapping input parameter.
In process flow palatte i could see Key as OUT and in C properties i could bind it to Key .
but i try to deploy this mapping i am getting error below
PF_PKG Create Error
RPE-02040: Internal error: KEY cannot be converted to a constant value. Please correct the value. If the problem persists then please contact Oracle Support with the stack trace and details on how to reproduce it.
TEST_PFCreate INFORMATIONAL
RPE-02071: Deployment has been aborted due to a previously reported critial error.
please suggest me how to pass parameters between mappings with in a process flow.

Hi
You have to use process flow variables. So the output of map A, say parameter P would bind to variable V and then the input of map B, say Q would bind to variable V. In this way you can push parameters from one activity to the other. Although the UI lets you bind B.Q to A.P, it should not, I think there is a bug reported on this.

How to bind mapping input parameter in process flow using OMB Plus

Hi
I have created a process flow with a mapping.
This mapping has a input parameter, that I want to bind to a variable using OMBPlus
OMBALTER PROCESS_FLOW '$process' MODIFY PARAMETER 'P_EOD_DATE_IN' SET PROPERTIES (BINDING) VALUES ('V_EOD_DATE') does not work as P_EOD_DATE is NOT a process parameter
neither does
OMBALTER PROCESS_FLOW '$process' MODIFY PARAMETER '$mapname/P_EOD_DATE_IN' SET PROPERTIES (BINDING) VALUES ('V_EOD_DATE') as the reference '$mapname/P_EOD_DATE_IN' is not valid.
Any suggestions ?
Best Regards

Binding variables in Process Flows

I'm attempting to bind a variable defined in the Start activity to a Mapping activity's Input parameter. When I expand the Mapping activity and select the Input parameter in question, it forces me to explicitly enter a value. It does not show the Start activity parameter in the Binding listbox.
This appears to work fine for other activities within a Process Flow (Email, FTP, Transform, Subprocess) but not with a Mapping. Is this a bug or by design?
I'm working on OWB 9.2
Dave

Hi David,
Sorry for the delay, I just tested this and mine nicely complies to what I want. Added a number input parameter to a mapping. Then added a number input in the Start activity. This works.
Then I tried to do a string input on the start and try to bind that, and this does give the your result.
Process flow only allows you to bind variables with the same data type (or equivalent). So please take a look at the datatypes for the mapping input and the Start activity parameter.
If they are the same (e.g. integer and number, string and varchar2) this works.

Process Flow Exit Parameters, Possible?

I want to send through variables from One process to Another within a Process Flow Package, is this possible.
I'm not able to add EXIT parameters to the END Object through which I can hand over values to the next process, how is this done?

Sorry, currently it is not possible. In the next release, END activity will support parameters.

Passing parameters from shell script to OWB process flow

Hi all,
I am running OWB process flow (using the template script provided by oracle) and i want to pass two date parameters as shown below:
sqlplus -s $SQL_USER/$SQL_PWD@$ORACLE_SID @$HOME_DIR/src/vmc_oem_exec_script.sql OWB_OWNER VMC_POST_DW_PF_LOC_SIT PROCESS VMC_NM1_PORT_MAIN "," "P_DATE_FROM=$DATE_FROM,P_DATE_TO=$DATE_TO"
How do i catch those values in process flow and pass those to mappings in Process flow?
Do i need to create PF variables with same names or any name will do?
Thanks in advance

This document is explaining how to pass data between activities in process flow.
I am passing parameters from a shell script.
Any ideas,how to pass parameters from shell script and then initialize the process flow variables based on those values and then pass them further to mappings.
Thanks

OWB embeded process flow - parameter binding problem

I've installed and Oracle 10g Database, after the database installation I added the Oracle Workflow server software. To complete the installation I ran the wfca.
Later I get to define a process flow in OWB (cheesy) and the process flow seems to be working well (I've done all the registrations necesary also ), but when I am trying to do the parameter binding is not working. I do get the window prompt for the parameter and I enter the date parameter ( I tried different formats like 'YYYY/MM/DD' 'dd-mon-yyyy'), but after I check the runtime in the web browser the parameter is not pass to next process. I tried many things for the last week but I cannot get it to pass the parameter from one process to another.
Any ideas,
HELP !!!!!

did u manage to resolve this issue? we are facing the same problem.

Process Flow and Passing Parameters to Mappings

I am missing something.
I have an Input Parameter on mapping Strategy_Start.
I want to pass a value from my Process Flow to the Mapping Strategy_Start that is in the Process Flow.
I have tried to create a Parameter on the Start that has a Literal value and bind that to the Strategy_Start Mapping.
That didn't work.
I tried to create variable and pass the value to the Strategy_start,
That didn't work, I got an error about binding to a out literal.
What am I missing.
I could not really find steps in Documentation for this.
I am using 11gr1
thanks for any advice or help.
greG

Ok,
For Literal Expressions It was easier than I thought.
In my Process Flow for the mapping that has a parameter,
I just set the value of the Parameter when looking in Explorer.
I thought I had to create a parameter or a variable and then pass that into the value. That is why it was yelling at me about
can't use a constant value as a parameter in value.
If this is not the way let me know, but it appears to be ok now.
thanks

Process Flow Parameters.

A quick question:
Does anyone know if it is possible to have a process flow pass variable values into variables defined in a sub-process? I mean, clearly I could have the main process run a transformation to write this value to a table, and then have a transformation in the sub-process retrieve it, but I would prefer a cleaner approach if possible.
Any ideas?

Aha! It was the Parameters I hadn't got figured out.
Thanks a lot!

Passing parameters in process flow

Hi All,
Is there a way to pass parameters between different process flow operators like transformation activity, mapping, etc using any variable. Either defining new variable or using existing variable. Does process flow provides any variables whose values can be changed by one mapping and used by mapping following it.
Any help would be appreicated.
Platform - OWB 10gR1
Regards,
Ron.

write a PL/SQL transformation, function or procedure either. Call the Transformation before the mapping, like if you want to execute that mapping or not based on the return vale.
"can be changed by one mapping and used by mapping following it"
Yes, you can. Log the value into database , then convert the following mapping as the PL/SQL transformation, where you can easily take the previous mapping output value, which has been stored. All you need some temp parameter table. The way you can define a table to be used for more than one case.

Confused: usage of process flow parameters

I'm wondering:
I wanted to use a process parameter as input for more than one process component. but when i bind it to the first component (e.g. a transformation) it is not possible to bind it again to the next transformation in the same process flow.
is this "normal"?
the only workarround I see is to create local var's and assign them with an assignment op.
can someone help to clarify the situation?

Hi,
usually it is no problem to bind a parameter from you START1 activity to several other activities in you process flow.
I did it in OWB 11.1 and 11.2.
Which version do you use ?
