Function Modules in Event Linkage

Dear all,
In the event linkage of workflow, we can find 3 types of function modules. They are receiver function module, check function module and receiver type function module. Can anybody explain what are they used for?
Thanks + Best Regards
Jerome

Hi Jerome,
Explanation for each of the FM's(Receiver Fm, Check FM, Receiver Type FM).
1) Receiver Function Module.
This is the main function module which will actually link the Object Event and Workflow Or Task.
Ex Event : BUS2012.ReleaseStepCreated
 Workflow : WS20000075
 FM : ZReceiver.
An Entry in SWE2(Event linkage) with above values Does mean "The workflow WS20000075 will start when Event BUS2012.ReleaseStepCreated is triggered with the help of ZReceiver ".
All Receiver Function Module should have standard interface(Same input and table parameters specified by SAP).
2)Check Function Module
This function module is used to prevent the event linkage.
It is called before the Receiver Function Module is being called.
Lets take the above ex:
Ex Event : BUS2012.ReleaseStepCreated
 Workflow : WS20000075
In this case if you want to do some checks before actually linking the BUS2012.ReleaseStepCreated and WS20000075 using Receiver Function Module then you can use Check function module to do validation and raise the Exceptions.
If any exceptions are raised in the Check function module then The Receiver Function module will not be called hence no EVent Linkage.
3) Receiver Type Function Module
This is the First function module to be called among three if it is specified in SWE2.
This Function module is used to find the Receiver type Dynamically. ie if you have not specified the reciever type(Workflow or Task) in SWE2 you can determine that at runtime using this Function module.
Reward if its helps. Feel free to ask for clarifications.
Thanks

GP: How to keep action sleeping until ABAP function module raises event

Hello experts,
I'd like to develop a gp process which contains a callable objects which keeps the process instance waiting until an abap function module send something like an event.
I don't want to put too much load on the machine and block expensive JCO ressources.
Does anyone have an idea how to solve this?
Thanks very much
Stefan

Hi Mike,
GREAT! Many thanks! Sometimes solutions may be so simple.
For all others who have the same problem a bit more in detail:
In your FM just enter as exception: CX_BO_ACTION_CANCELLED and mark 'Exceptn. Classes'.
Declare your class method with the exception cx_bo_action_cancelled.
In your class method just enter your FM via the 'Pattern'-Button.
The Pattern will show only the Import- and Export-Parameters but not the exception (class).

How to Debug During Event Linkage( Reciever Function Module )

Hi all,
If anybody knows how to debug a reciever function module in event linkage method then please respond.The scenario is that whenever service order is changed the change event will fire the custom business object which has a supertype BUS2088.

Hi Nishanth,
You can debug event linkage using the transaction SWUE.
Here you can raise an event and specify an object key (using an already created service order).
Just flag the trigger receiver FM synchr. checkbox and your break point will be hit.
Hope that helps.
Cheers,

Read workitem Container Value in Terminating event Check Function Module

Hi
I have some problems reading work item data / values of a work item container element in a check function module on a terminating event Do any of you know if this is possible, and if so, how its done ?
In My scenario I have created a multiline approval step for my business document, one task pr Line Owner. The Event Approved is defined as a terminating event for this task, and the line owner is passed to the task container.
Now, when I raise the event, with the line owner as an event parameter, I would like to check if the line owner on the raised event, matches the line owner in the task container in question in a check fm. But here I faced the problem, that only event data, and not work item data, are passed to the Check Function module.

Morten Nielsen

Hello Morten, hello Arghadip,
in the instance linkage's check function module (entered via transaction SWEINST) you'll have the workitem-id in the system event parameter EVTRECEIVER_ID
With this number you can use the frame work in order to read the work item container.
This is a sample coding, how you access the correct work item container using SAP Enterprise and it's new OO frame work, which checks on the terminating event of BUS2105.Released the correct release code for a work item.

Function Module to find Business Event type

Hi Experts,
Do we have any Function Module to get Business Event Type(BET) if Person(P) is the input.

Go to SE37 and give application component PE and search for you requirement

Process Chain Review Question: function module/ABAP program/Event

Hi,
1. Can you tell me a bit more about function modules such as RSPC_CHAIN_ACTIVATE_REMOTE
2. What are function modules in general terms. i.e. What is their role?
3. How do I see all function module available?
4. When is function module used instead of ABAP program?
5. How do they help in the support and monitoring of Process Chains?
6. I am getting confused over the following under process chains job, event, function module and ABAP Program
Thanks

2. What are function modules in general terms. i.e. What is their role?
Function module return a value ( most of the time), they return some value either a single value of rane of value or even a table. Example: FM to return fiscal period gieven the fiscal vaeiant and system date.
3. How do I see all function module available?
Go to Se37 and this is function builder. You will find FM starting with RS* more useful. You cna also create your own in Se37.
4. When is function module used instead of ABAP program?
In addtion to answer I gave in 3 above, program is used to check some logic and update some tables or give screen output.
You may note FM is also a program.
5. How do they help in the support and monitoring of Process Chains?
As I said, for monitoring chains, use Sm37 and logs in RSPC.
6. I am getting confused over the following under process chains job, event, function module and ABAP Program
I am not clear what are you looking for.
You cna schedule a FM or a program to run in a chain. Is that what you mean?

Message cannot send if P.C was started by function module, ok for event

Hi Expert,
I face a very strange situation
As you know, we could create message for each process chain steps
I have one process chain which contains message if it is start and when it is finished
The start condtion for this process chain was after event
But the strange situation is
1. If this process chain was start by function module: RSPC_API_CHAIN_START
The message in process chain cannot be sent
2. If we trigger event for this process chain, the p.c could be execuced correctly
Could you kindly let me know the possible reason for this issue?
Thanks and best regards
Alex yang

Root cause is the function module we use will run the process chain in dialog module (no batch job). So system cannot send the mail.
If run it in background, we could get the mail

Event log for events from function module BP_EVENT_RAISE

Hello experts,
where can I look at the event log which where raised with the
function modul BP_EVENT_RAISE.
Thanks.
Regards, Lars.

this function module does not write a log by itself. and actually i would not know what should be in that log. usually you set up an event to trigger a follow-up process, so there's either the event was successfully triggered and your follow-up process has been started ... or it hasn't, which means: something went wrong ...
Edited by: Mylene Euridice Dorias on Apr 16, 2008 10:42 AM
i was just sap-netting with your problem and i found note [919458|https://websmp230.sap-ag.de/sap(bD1kZSZjPTAwMQ==)/bc/bsp/spn/sapnotes/index2.htm?numm=919458&nlang=EN&smpsrv=https%3a%2f%2fwebsmp205%2esap-ag%2ede] where they use program BTC_EVENT_RAISE instead of BP_EVENT_RAISE. the note says this program writes at least a line in the job-log so it might fulfill your requirements ...

Function modules to generate the event required

Hi guys,
I have created a workflow but its start event is not getting triggered though condition data is correct.
I want to debug and see when the Business object's event is called.
Can you please tell me name of the Function modules to generate the event. This way i'll put a breakpoint on those and check the flow ?
Regards,
Shaili

Thanks Surjith
I'll check this FM.
Also I want you advice on the real issue i'm facing.
I have created a workflow giving some condition with start event as CHANGED of BUS1006. Now the work of populating the field in condition is done automatically by a BADI i've created.
The issue is that the workflow is not triggerd during automatic population of teh field but is triggered when i explicitly populate the field.
The reason might be that CHANGED event of the business object used is triggered before the SAVE BADI has populated teh field. So CHANGED event 's condition is not satisfied before the BADI has finished updating.
Is there a way tackle this. Can I somehow push back the trigger of workflow...I'm new to workflows so please don't mind if this sounds foolish

Shaili

Function module to populate itab with event's name

Is there any function module which would populate internal table with all the events name of the submitted program.Actually I used F4_PROG_EVENT but it is generating a alv popup with event's name but not storing anything in the internal table.

Hi,
Check FM: REUSE_ALV_LIST_DISPLAY
Export
It_events : internal table with a list of all possible events of ALV and their corresponding routine names.

Dunning FPVA/FPVB : Need UserExit Event Function Module

Hi Guys,
I need to develop an enhancement in dunning activity. In which custom function module will be triggered in a dunning activity to check if among the dunned items.
This custom function module must have table T_DFKKOP filled with open items from the contract account been dunned.
I found one event i.e. 311. But I am not sure of its use and when it wil be called.
any response will surely help.
Edited by: Nikhil Jathar on Dec 1, 2008 10:47 PM

SPRO->SAP Customizing Implementation Guide->Financial Accounting (New)->Contract Accounts Receivable and Payable->Business Transactions->Dunning->Configure Dunning Activities.
Create your Z function module and attach over there with the following parameters.
""Local Interface:
*" IMPORTING
*"     VALUE(I_TFK047L) LIKE TFK047L STRUCTURE TFK047L
*" TABLES
*"      T_FKKMAZE STRUCTURE FKKMAZE
*"      T_FKKMAKT STRUCTURE FKKMAKT
*"      T_FKKOP STRUCTURE FKKOP
*"      T_FKKOPK STRUCTURE FKKOPK
*"      T_FIMSG STRUCTURE FIMSG
*" CHANGING
*"     VALUE(C_FKKMAKO) LIKE FKKMAKO STRUCTURE FKKMAKO
*"     VALUE(C_FKKKO) LIKE FKKKO STRUCTURE FKKKO
I guess your requirement will solve in this user-exit. if it is not soleved then tell me , What u want to do in the user-exit is the main question ? bcz there are so many user-exits are there for your question.
Please Allot Points if it helps

Webdynpro Function module linkage

Hi all,
We have a requirement where in we are required to display the employee bonus details in portal.The standard configuration does not meet this requirement ,hence we have configured the portal by adding a new column to display employee bonus.The custom Function module which we had created is working perfectly in R3.Can somebody detail the steps involved in linking the FM with portal.
Note :- The FM which we have created is normal FM and not Remote FM.
Thanks and Regards,
Kiran

Hi,
Duplicate post.
Pls check the same in the ABAP General.
Pls read the rules.

Receiver Type Function Module in SWE2 use of export parameter.

i am trying to understand the underlying concept in following things:(neednot to say i have searched alot and read sap documentation already).
In event type linkage table say i have an entry for BOR -> AFVC_PM.
As per sap Documentation says all these FM will trigger in following way.
1 Check Function Module (to place any validations/checks)
2 Receiver Type Function Module ()
3 Receiver Function Module.
Thats fine.
This is what documentation says about Receiver Type FM(2nd FM) not Receiver FM(3rd FM).
This FM has 1 export paramter
Export parameters
RECTYPE type SWETYPECOU-RECTYPE Receiver type( Result of the evaluation by the receiver type function module.)
if i am understanding this right, in this FM receiver type will be decided .
i have placed BREAK-POINT in this FM and passing value WS90000024 (Workflow with simple mail step) in export parameter RECTYPE.
after everything executed successfully why i can't see that mail in my inbox.
Please correct me if i had misunderstood the concept .

ok,indeed i was missing this thing.
i got the mails in inbox.
but why i can't see this value WS90000024 of this workflow ()which is going to be triggered ) in parameter RECTYPE.(its empty).
it is empty after the receiver type function module execution is complete.
below is workflow template,

How to trigger Alert with Event Linkage?

Hi,
Can any one tell me the process how to trigger alerts with event linkage? I am successul in triggering by calling function module SALRT_CREATE_API.
my scenario is...
when a purchase order is cancelled, i have to trigger an alert to the concerned department head throgh Alert Inbox and external mail also.
Plese guide me..
Regards,
Dhanunjaya Reddy

Hi,
now i am getting alerts from Event Linkage.
Here i take the scenario Sales order change.
BOR object : BUS2032
Event : Changed
Receiver type : <my alert>
Receiver call : Function Module
Receiver Functiona Module : SALRT_CREATE_VIA_EVENT
Linkage is activated.
when a sales order is changed receiver function module triggering the alert which is defined in Receiver type. That i am getting in my alert inbox. Upto this.. it is cleared.
Now the scenario is.. about Alert Container
in alert container i take element is BOR Object type BUS2032.
the questions are..
1. Is it correct to defined BOR object here to get data when Sales order has been changed.
2. What are the properties i have to take in Properties tab?
3. How to use alert container parameters in short and long text?
Here my clear intention is when a sales order is changed.. i have to get the data related to that sales order and it has to show in Alert.

In HCM form & process Workflow event linkage changed to inactive status.

Hi,
In HCM form & process event linkage is activated in HRASR_DT and workflow object .
Now once we complete the process from EP portal ,reference number is generated and enteries are created in table T5ASRPROCESSES .
In SWEL,event is triggered and linked with the same workflow.
Now the problem is,thesre is no workitem in SWIA with this workflow numbmer and the event linkage also changed to inactive status ( both in proces and workflow )after we complete the process from EP.
Thanks
Manoj

Hi
When you are delaing workflows with HCM Process and form the behaviour is slightly different from the normal.. In order to check why the event linkage is inactive the possibilities are
1. Either there are some chnages done in the workflow and it is not activated from the transaction HRASR_DT.
2. The other possibility is that you might have directly actovated the workflow from SWDD transaction and if you have done in this way then it is a wrong way of generating and activating the workflow
Follow the below steps to find the error
1. Execute HRASR_DT txn and try to activate the workflow from here. If you try to activate the workflow from this transaction the check function module which is linked to the workflow will be knowing that for which specific process which workflow has to be triggered..
so in HCM process and forms frame workf it is always suggestable that try to create the workflow from HRASR_DT transaction using forward navigation and activate the respective event linkages.
The other point you need to check is make sure that all the respective program exit classesare included in the basic data of the workflow other wise even if you miss the program exit classes in the basic data the workflow will not be able to start its process/execution.

Pavan
