BOR vs. CLASS

Hi to everybody,
I'm developping an application to manage authorization requests.
I began it using BOR, for the reason that i'll manage different status creating them by SAP Workflow.
When I started with the application, we use the BOR FORMABSENC like an example, but while I were developping I found out several problems and I decided to create it with CLASS and SAP Work.
I would like to know what's the difference between BOR or Class, which of both options you recommend me and why you've decided on it.
I´m looking forward to a response soon.
Thank you.
Nicocer.

hello,
It is always good to adapt to object oriented approach for all sort of ABAP development. Using BOR is the conventional style of build. You will have better control on the program flow and design using OOABAP. Read some demo chapters available on internet of SAP press book "official abap programming guidelines" for your answer.
Thanks

BOR or CLASS for Document Management Service (not SAP DMS for PLM)

Hi All,
Does anyone know if there is already a BOR or CLASS that can be used in Workflow that works with the Document Management Service? This is in reference to the diagram displayed in the following link
http://help.sap.com/saphelp_crm40/helpdata/en/15/aea9375d79fb7de10000009b38f8cf/content.htm.
I assume that there must be a BOR or CLASS that uses DMS that I can use with workflow.
Thanks.

BOR to Classes conversion

As BOR is being phased out is anyone aware of any tools around to convert some useful BOR's to Classes.
I think in general in workflow one should try and use classes and objects wherever possible rather than the older BOR method.
A lot of supplied SAP workflows however are still based on BOR so this area could become a bit of a minefield especially in CRM and similar type of processing.
As new projects come on stream I'd be interested to know how people are going to handle this topic.
Cheers

This doesn't address the topic. All of the above features can be done via OO classes --you can of course have multi-line objects and "virtual attributes" in a class.
A problem with BOR is that you can't easily call these from "Classical ABAP" programming so say you want all the partners of a sales order you normally have to code the functionality yourself using the relevant tables rather than try and get the attributes of a relevant BOR in your program.
However once you've defined say a SALES ORDER class then any ABAP can access the public attributes and methods of this class .
With the BOR it's OK via workflow but a "Normal ABAP" program has to do some fancy coding using the "SWO" or workflow macros and functions to access the attributes of the BOR.
Since these are internal SAP macros and could be deprecated at any time it's really not surprising that outside the Workflow environment BOR's are rarely used in standard ABAP programming.
BOR was a "stepping stone" used by SAP to implement some of the features of OO abap before OO abap became reasonably powerful itself.
Inheritance, encapsulation etc etc are all standard in OO -- not restricted to BOR's.
The trick is to ensure your new class has the functionality of the old BOR and use that wherever possible on new projects.
Like BOR if you extend methods and attributes you don't need to change any existing programs using the relevant classes.
I'm sure the next major upgrade of sap will implement many more business classes -- the old BOR could be retained by simply calling a Class of the same name having the same attributes and objects for legacy code and workflows.
For example here's some ABAP code to call a method which returns the Long Text of a Service notification BOR ZBUS2080 (delagated BOR BUS2080)
You can see it's quite a "Dogs Dinner".
Much more simply and easily done of course if you had a similar CLASS available. (call me=>) etc.
Program ZZREADBOR.
Sample program to execute a method of a business object
or return an attribute of a Business object
can be used in or outside of Workflows etc.
Use this as a model
Note on some definitions used in WF / Object
programming.
A container is a special type of "generalized"
parameter used in workflows for passing data
between steps.
You can use these in "Normal" programming
It's just a generalized structure for holding
data.
An Attribute in this context means a field e.g Short
text. The attribute can be a table (multi-lined)
as well.
The attribut is defined in the attribute list
of the business object
Use transaction SWO1 to see the list.
Operations on containers are done via
standard SAP Workflow macros
swc_function such as swc_create_object.
You must supply a key to instantiate the object
and the object name
(Instantiation means just supplying
the objects key --such as
in the case of a sales order the key would be
the sales order number).
Parameters
Enter Business object name e.g ZBUS2080
key of business object e.g sales doc nr etc.
Attribute you want if getting an attribute property
Method name if executing a method.
For retrieving attributes the data is returned
in field return.
For Methods a little extra work is required as follows:
For Methods you may need extra container
parameters such as
tables (swc_get_tabe container containerElement Itab)
To see what elements are needed have a look at the
Method code (transaction SWO1=== select
the business object(display) chose the method and then
select the program button
container parameters will be identified the code
by swc_set_element / table for export parameteres
swc_get_element / table for import parameters.
ensure you set your container(s) to persistent
this ensures the container exists throughout
the whole run and is available to sub programs
function modules, methods etc.
if you don't do this then the container only exists
in the program and disappears when you enter a function
module method etc etc.

for swo invoke -- access type 'G' ====> get attribute

this function is executed internally.
in the perform (p_method) statement the sap kernel knows
that the program is actually a business object type of program
not a "Normal" abap so the perform gets handled a little
differently than the usual perform statement.
You cannot execute the BOR program via SE38.
set any input and output parameters
for your method.
You will have to code them here
swc_set_element container 'User' p_key.
l_invoke-object = object.
l_invoke-lobjtype = p_method.
l_invoke-verb = p_method.
l_invoke-objkey = p_key.

read comments above again to understand the difference
in how this statement works compared
to a normal perfom xxxx in program yyyy.
if you have more parameters such as container tables then add them
to the tables statement.
for example to get long text and other info from business object

      notifpartnr like bapi2080_notpartnre occurs 0,
      return2 like bapiret2 occurs 0.
swc_set_table container 'NotLongText' notlongtext.
swc_set_table container 'NotItem' notitem.
swc_set_table container 'NotifCaus' notifcaus.
swc_set_table container 'NotifActv' notifactv.

BOR Object and ABAP Class

Hi,
Can anybody say when to use BOR object and Abap class in the task with an example.
Thanks,
Mugundhan

There is no any specific condition or rule that for this purpose you need to use BOR and Class , it depends on your requirement. not only the requirement but also the new techniques to make classes not just as simple way to create objects but when you use classes in the Workflows they are not simple classes but they are BUSINESS CLASSES which makes a lot of difference.

Error in executing workflow.

Hi All.
I am executing a workflow task individually for Change document. ( CV02N)
But after executing workflow if i check in workflow log i am getting following error.
Error: subdocs could not be aligned (009)
Could any one advise me why this is happening and what to do...?
Thanks ,

I've never had this problem, so here's just an educated guess: Are you changing one part in a multipart document?
In any case you should provide a lot more information to make it easier for everyone to help. Just a few examples:
- Is the workflow a SAP standard one, or a custom one?
- Is the object (BOR or class) a SAP standard one, or a custom one?
- Do you get this error every time (for all documents) or not?
- What is your SAP release?

Business object /Enhancement/Badi for Payment proposal (F110S)

Hello All
I need to trigger a workflow when payment proposal(F110S) is executed.
Is there any BO available or is there any Badi/enhancement available where the workflow can be triggered.
Thanks

Hello,
Your best bet would be to search this forum or the web for F110S and hope someone else asked the same question and got an answer. Otherwise, start looking through the list of BORs in SWO1 to look for some likely names.
It's also possible that you'll have to make your own BOR or Class. It's not that difficult, but it's preferable to go with an existing one.
Please let this forum know the result of your search for the benfit of future users with the same question.

How can i find (Debug - method) the flow of program in workflow at run time

Hi All,
I working in Workflow monitoring. When a workflow is set into error in SWPR , i need to analyse the error and report it. In many cases the error happens in the method of class / BOR. So i could not find out the what happens inside the method. I am doing this in an productive environment.i am not given to Run any METHOD or BOR or CLASS ? How can i make my workflow monitoring better to show exact error ?
Thanks in advance !
Richard A

Dear Richard,
You cannot debug a method by directly setting a break point as we do normally.....u can do this by
just putting an infinite loop at the point where u want to set the debug point inside the method.
Execute the workflow where this method is being used.
Then go to SM50, here you will find your method which has gone into infinite loop.I debug mode change the value of the variable so that it can move ahead of the infinite loop.
Now you can debug easily and find out where the problem lies.
Do reply back in case of any query or even if yr problem is resolved.

Workflow and business process

hi,
may i know where (transaction code or table or configuration path) can tell that which business process has workflow activated.
for example PO me21n, how do we know that me21n has workflow activated or not.
thanks

Hello,
You can also look in SWE2 to see which linkages are active, and which ones could produce workflows if they were activated.
Making the connection from the BOR or Class back to the transaction is a bit more difficult. You could try executing the transaction (e.g. creating a PR) and then look in SWEL (event trace) to see if any events are created.

External Program

Hi Friend,
How can we access or execute an external program in my Workflow ?
Bye..

Hi Sk,
What do you mean by External Program?tell me some details.
if you meant by calling a module pool or a report or( any transaction)
in workflow then it is possible through calling BOR or Class.
you can call an Object(BOR) and write your code in the method of that object
or can write code in a class(se24) and call the class.
Thanks & Regards

BOR Objects in ABAP OO class

Hi
I am using a BOR objects, but in one of my activity I am trying to use a Z class. In the method of the Z class I want to get some of the attributes of the BOR class.
I have followed the same approach ( Defining constant ) as mentioned in the blog by Jocelyn Dart.
I am able to get the Binding in the workflow but not able to get the attribute value or instantiated object in the method.
How do I get those attributes or the instance of the BOR object in the method. Am I missing something?
Thanks
Dhaval

Hi
Well I wanted to achieve something as follows:
1) The workflow was getting triggered from an Event of the BOR. So the binding was from the event to the workflow
2) Now the second step in the workflow was a method of a Zclass in the workflow. Somehow I was not getting the key of the BOR to the class so that the class can be instiated. ( Say the PR number or PO number which triggered the event)
I am able to do it using static attribute of the class to instiate the class. I do know whether the approach is right, but somehow it resolved my issue.
1) I declared a static attribute in the class.
2) Defined a container and hold the value in the container from the event object id. ( This holds the PO number which triggered the workflow )
3) In the binding between the workflow and the task where my class was used, I passed the container to the static attribute of the class.
4) In the class method FIND_BY_LPOR, I used the static attirbue instead of LPOR-INSTID to create the object.
Thanks for you help.
Regards
Dhaval

BOR Object or ABAP Class

Hi Experts,
We are implementing the Leave Request WF using WS12300111. The user raises a leave request from the portal.
As per the functional point of contact, they have said that this WF can be set up in the configuration in SPRO to be triggered when a leave request is raised.
When we saw the standard SAP provided WF, the steps in it are based on ABAP class. I just want to know if the approach has to be only using ABAP classes or can BOR objects be used.
We require some customizations in the sense, we need to add some custom logic to retrieve some data from some custom tables and also display the same.
Kindly let me know if we need to use ABAP classes or we can use a BOR Object.
Cheers,
Belinda Clarke

Hi Karri,
Thanks a lot for your response.
I was actually evaluating the possibilities of the same as our WF consultant is currently on leave. I was just seeing a scenario where they have used BOR Object for Travel and Expenses module. When i saw the standard WF for Leave Request WS12300111, I was seeing mainly ABAP Objects and there was no BOR objects used.
I just wanted to confirm whether we could create a BOR Object or go on with the ABAP Classes. Does the ABAP Classes involve a lot of effort? We need to actually send email notifications and add some new steps etc...so was just thinking as to which would involve more effort.
We need to actually retrieve data from table PTREQ_ATTABS and send the email notification to the concerned user whenever the leave request is approved/rejected/cancelled as shown below :
Your leave request has been approved/rejected
Name : abcde
Emp No : 123456
Type of Leave : Annual Leave
Date : 7th July to 11th July
No. of Days : 3 days
So do u imply that all of this can be done with an ABAP Class
Could you kindly guide us.

Integration of BOR functionality into a ABAP-OO Class

Hi together,
we are planning a WebDynpro application in which we are using about ten ABAP-OO classes. The functionality of that classes are using BOR-Objects. Since we are using the M-V-C pattern, we like to create Entities, e.g. "Business Partner" within our model. There is already a BOR "BP" existing. We like to use this BOS-Object for implementing the ABAP-OO Entity Class. By doing it that way, we are sure that the new object will satisfy any SAP compliance.
Is there a standard way to integrate the functionality of BOR-Objects into an ABAP-OO Class?
Best regards
Thomas Wetzler

Hi,
have a look how SAP is handling this, for example in class CL_ATTACHMENT_LIST.
There is an include CNTN01_SWC with the definitions of the data-types and macros you need to handle the BOR-objects and containers.
Include this in the local class-implementations of your global class. Then you can handle the BOR-objects inside the methods as usual.
Regards
Dirk

BOR reference in ABAP Class

Hello,
I am writing method in ABAP class which I will link to the Workflow Step. I want to access values of one of the Workflow Element which is Multiline and refering to BOR Object Type. My queries are as below:
1. How should I define Importing Parameter of Method which will import values from the Workflow Element which is Multiline and refering to BOR object type.
2. If I change value of that Workflow Element (Multipline refering to BOR object type) in ABAP class method, will it be automatically reflected in Workflow Container due to binding?
Edited by: Ashwin Sonkusare on Apr 1, 2011 3:35 PM

Hi,
1. How should I define Importing Parameter of Method which will import values from the Workflow Element which is Multiline and refering to BOR object type.
Please create a table type same as workflow multiline element type. ( You can also use standard table if present ).
Then use this table type as the type of the import parameter of the class.
Then u can pass the multiline element of workflow to abab calss
2. If I change value of that Workflow Element (Multipline refering to BOR object type) in ABAP class method, will it be automatically reflected in Workflow Container due to binding?
If u change the Workflow Element (Multipline refering to BOR object type) in ABAP class method, then u need to update the values of the workflow multiline element through reverse binging ( binding abap class to WF ).
Thanks and regards,

BOR or ABAP Class for MM41

Hi all.
I am wondering whether anyone ever use workflow in transaction MM41.
Does SAP provide standard BOR or ABAP Class for transaction MM41.
I know there is BUS1001006 but this only get triggers from MM01.
Does user exit or BADI is the only way to trigger workflow from MM41?
Thanks

Hello,
It might help if you said what MM41 was.
As usual, turn on the event trace (SWELS), create and save something in your chosen transaction and then check the event trace (SWEL) for any events.
