Cons of using BPM

Hi All,
I know BPM is used when I need to implement a scenario which needs stateful processing. Also BPM is used when I need to go for a synchronous-asynchronous bridge. Also BPM supports good error handling.(Pls correct me if I was wrong any where)
When BPM provides me a lot of advantages why should i avoid using BPM as far as possible. Coz when I go through some previous threads a lot of experts advise not to go for BPM. Can you pls tell me why is that? Any docs where I can find cons of BPM would be of great help.
Thanks & Regards,
Jai Shankar.

Jai,
The mappings in XI get executerd on the Java Stack, whereas the BPM is executed in the Business Process EnNgine , which is a part of the ABAP stack.
So, a BPM has multiple calls between the JAVA and ABAP stack and causes a performance bottleneck
Like you mentioned BPM provides Stateful Message Processing and from what I have seen, normally during design stages of any XI Interface, when the choice is between whether to go for a BPM or not , the following questions are asked,
1. What is the number of times the interface will be run per day.
2. Can the interfaebe implmeneted without a BPM and if yes, then what is the approach and what is the disadvantage of avoiding a BPM.
ALso, http://help.sap.com/saphelp_nw04/helpdata/en/43/d92e428819da2ce10000000a1550b0/content.htm
Just check the Step types with low and high resource consumption and normally , the decision is based on the entire flow and the requirement of the interfaces.

Bhavesh

We need to create output file for each record. In this case, the system should generate 26 output files.
I imported the RFC and created the required interfaces and designed BPM also.
Start --> Receive step --> Synchronous Send --> Asynchronous Send
But, I stuck in how to deliver each record to the output file from BPM.
Any idea, friends. (like using BPM Multi-line option. or 'Receiver From' property in the Send Step)
Kindly help me friends to solve this issue.
Thanking you.
Kind Regards,
Jeg P.

Hi
You can do it by creating one another message interface having structure same as your table.
What you have to do is create a mapping in such a way that for each record in table one message(newly created) must be created.
Use that mapping in an interface mapping, remember occurence of target message should be 0..Unbounded both in message mapping and interface mapping.
Now create one single line message and one multiline message in BPM for newly created message.Use transformation step with new interface mapping, mention source(RFC response) and target message(use multiline element of new message) for the transformation step.
Use send step inside a block,set block mode to "forEach", and attach new message to that send step.
Use multiline and single element of new message in the property window of block.
Now your BPM will look like
Start ---> Receiver ---> Synchronous send ---> Transformation ---> Block ---> Async Send(within block)
I think in this way you can implement what you want.

Pros & Cons of Using SAP PI Interfaces for Report Generation

Hi Guru's
I have a Scenario's like
I have to generate a customized report in SAP with the main data's available in SAP ECC and some required data available in the Legacy System.
I want to know the Pros & cons of using SAP PI RFC/Proxy adapter interface to get the data from the legacy system for each time the user execute the report in SAP ECC.
Thanks in Advance

There are couple of "dimensions" to consider in your PI interface design. For exemple when you are running the sizing exercise (Since we are considering adding a net new interface), you will need to capture specific information about new interface.i.e. S/A, adapters, frequency, avg payload size. etc..Note that the last two attributes will be hard to size properly in this case since you can't predict how frequent the end user will run the report which will impact the latency time required to pull the data. Latency will affect the user experience as visible side affect and definitely the SLA for other interfaces running at the same time.
On the other hand, the data you are trying to retrieve from the legacy won't be used for transactional purpose but for the end user to pull KPIs from the system which can affect ECC as well. You may end up doing lot hot fixes for your report (Assuming that the report is a medium complexity code)
There are other factors to consider but let's consider these are the major one.
Cheers,

Processing large volume of idocs using BPM Processing

Hi,
I have a scenario in which SAP R/3 sends large volume say 30,000 DEBMAS Idocs to XI. XI then sends data to 3 legacy systems using jdbc adapter.
I created a BPM Process which waits for 4 hrs to collect all the idocs. This is what my BPM does:
1. Wait for 4 hrs Collect the idocs
2. For every idoc do a IDOC->JDBC Message transformation.
3. Append to a Big List
4. Loop at the Big list from step 4 and in the loop for
5. Start counter from 0 and increment. Append to a Small List.
6. if counter reaches 100 then send a Batch JDBC Message in send step.
7. Reset counter after every send.
8. Process remaining list i.e if there was an odd count of say 5300 idoc then the remaining 53 idocs will be sent in anther block.
After sending 5000 idocs to above BPM following problems are there:
1. I cannot read the workflow log as system does not respond.
2. In the For Each loop which loops through the big list of say 5000 idocs only first pass of 100 was processed after that the workflow item is not moving ahead. It remains in the status as "STARTED" but I do not see further processing.
Please tell me why certain Work Items are stuck is it becuase I have reached upper limit and is this the right approach? The Main BPM Process is also hanging from last 2 days.
I have concerns about using BPM for processing such high volume of idocs in production. Please advice and thanks in advance.
Regards
Ashish

Hi Ashish,
Please read SAPs Checklist for proper usage of BPMs: http://help.sap.com/saphelp_nw04/helpdata/en/43/d92e428819da2ce10000000a1550b0/content.htm
One point i'm wondering about is why do you send the IDocs out of R/3 one by one and don't use packaging there? From a performance stand point this is much better than a bpm.
The SAP Checklist states the following:
"No Replacement for Mass Interfaces
Check whether it would not be better to execute particular processing steps, for example, collecting messages, on the sender or receiver system.
If you only want to collect the messages from one business system to forward them together to a second business system, you should do so by using a mass interface and not an integration process.
If you want to split a message up into lots of individual messages, also use a mass interface instead of an integration process. A mass interface requires only a fraction of the back-end system and Integration-Server resources that an integration process would require to carry out the same task. "
Also you might want to have a look at the IDoc packaging capabilities within XI (available since SP14 i believe): http://help.sap.com/saphelp_nw04/helpdata/en/7a/00143f011f4b2ee10000000a114084/content.htm
And here is Sravyas good blog about this topic: /people/sravya.talanki2/blog/2005/12/09/xiidoc-message-packages
If for whatever reason you can't or don't want to use the IDoc packets from R/3 or XI there are other points on which you can focus for optimizing your process:
In the section "Using the Integration Server Efficiently" there is an overview on which steps are costly and which steps are not so costly in their resource consumption. Mappings are one of the steps that tend to consume a lot of resources and unless it is a multi mapping that can not be executed outside a BPM there is always the option to do the mapping in the interface determination either before or after the BPM. So i would sugges if your step 2 is not a multi mapping you should try to execute it before entering the BPM and just handle the JDBC Messages in the BPM.
Wait steps are also costly steps, so reducing the time in your wait step could potentially lead to better performance. Or if possible you could omitt the wait step and just create a process that waits for 100 messages and then processes them.

Christine

Help needed in Multiple Receivers sceenarios using BPM

Hi,
I am new to BPM. As per my requirement, based on a business logic i may split the messages into two at message mapping. If i have spitted the messages into two, it should go to different receivers. Or if my logic hasnt splitted the mesaage means it should go to any one of the receivers. I also expect response from the receiver system once its done successfully.
Could you help me how to do this using BPM?
Thanks & Regards,
Senthil.

Hi,
You can do it without BPM also, by using MultiMapping. If only splitting is required then I would suggest not to use BPM since it will consume much memory. Instead you can use multmapping.
For Multimapping, go to messages tab in message mapping and select your different target structures and map it as per your requirement. In Integration Directory, go to advanced Interface Determination and proceed.

Asynchronous, but need Ack without using BPM and IDocs.

Hi Experts,
                 I would like to do a scenario i.e., "Asynchronous communication, but need Acknowledgement without using BPM and also without using IDocs whether it is sender side or receiver side". Please help me.
Thanks in advance
Srihari.

Without using BPM will be little longer process. But the alternative way is to add one more receiver in the receiver determination and send some file to that location with the actual mapping getting executed for the actual receiver. and in the second interface you can get the file created at second receiver back to the source location. But this will be little long as compared to synchronous scenarios.
Flow:
Source
          Receiver 1--> Actual mapping as per requirement
          Receiver 2(For Ack)--> Create a mapping with blank file sent to Receiver
Receiver 2-->File Adapter--> Source through 2nd mapping/interface and keep the File adapter pooling interval around 5 sec or less so that you can get the file back to source location.

Multi-Mapping and Message Split using BPM

Hi All,
Could anyone pls let me know clearly how message mapping can be done for this weblog
/people/sudharshan.aravamudan/blog/2005/12/01/illustration-of-multi-mapping-and-message-split-using-bpm-in-sap-exchange-infrastructure
Thanks,
Ram

Hi,
When you are doing Message mapping after adding the Messaget types for source and target messages. You can click on the "" button in the target message and add one more tab. You can go to Message tab as shown in the 5th image and click "" button to add one more message type. Then do the mapping as usual.
Based on the value of the element(name), the node of input(details)should be directed to one of the two message types
Here in this blog it is done based on the Name.
You need to use IFTHENELSE boolean function and do the mapping.
Thanks,
Prakash

File to Idocs using BPM

Hi,
Current Interface Flow - File (xml) to Idoc (single Idoc type)
Thirdparty sends a File for Goods Receipt. This file may have multiple orders.
Orders are sorted in an xslt by ORDNUM. Each record has a delivery type (Deliver Type PO or Delivery Type STO). For each order Graphical Message mapping occurs.
In case of PO, inbound delivery number and item number have to be received from ECC via an RFC call and passed to VBELN and POSNR. While in case of STO, source field ORDNUM and ORDITEM are passed to VBELN and POSNR. (RFC call happens only for POs, not for STOs)
In case of STO, TCode will be MB0A.and IDoc would be WMMBXY (As is the case right now)
In case of PO, there may be two cases -
a) There is at least one response from ECC for all the line items inside an order --> in this case TCode will be MB0A and IDoc is WMMBXY .
b) If there is no inbound delivery number for any line item from ECC inside an order --> TCode MB01 will be used and IDoc used is WMMBXY
So for all the above cases Target IDoc is WMMBXY.
Changes to be done - Now File (xml) to Idoc (Two different Idoc types, WMMBXY and DELIVERY03)
Now there is an additional requirement that I will be using an additional IDoc (DELIVERY03) in above case a).
I want to use BPM in this case
1) RFC call in message mapping to get the inbound delivery number (for POs only) (Should be before the message enters BPM)
2) Separating the messages based on IDoc type
3) Interface / Message mapping for each IDoc type
4)Send the message to ECC
Please suggest how to proceed with BPM
Thanks,
Varun

Hey,
Check in the correlation editor, where you define the condition.
Whether the data type of the XPath is string and whether it matches with the data type of the messages that you have selected.also make sure the type of the correlation variable is string.

Idoc(receiver) message splitting using BPM

Hi,
could you provide some blogs which is useful for Idoc (as a Receiver) message splitting (1:N scenario) using BPM.
I have gone thru some of the Blogs, i didn't find good one according to this scenario.
Thanks
Praba

Hi Michal,
Thanks for ur reply.
You said " if you have one message and want to have multiple IDOCs
there is no need for a BPM -
you just need to change IDOC occurance - that's all"
I agree to your point.
My scenario is more or less same but "With single message , i need to generate multiple Idocs" based on synchronous proxy response from R3. That is the reason we already gone with BPM.
Already i used the BPM in my interface due to req. It was working. Earlier i was posting single Idoc to R3 with multiple Header segment (each Header segment has one quantity)
Now due to req. change, for each single quantity (quantity is my source Message Type field), i need to post single Idoc to R3 if i get response from R3.
My XI version PI 7.0 SP14
Idoc structure:
 <xsd:attribute name="SEGMENT" type="xsd:string" fixed="1" use="required"
xmlns:xsd="http://www.w3.org/2001/XMLSchema" />
 </xsd:complexType>
- <xsd:complexType name="WPUWBW.WPUWBW01";>
- <xsd:annotation>
 <xsd:documentation>POS interface: Upload goods movements</xsd:documentation>
 </xsd:annotation>
- <xsd:sequence>
<xsd:element name="EDI_DC40" type="EDI_DC40.WPUWBW.WPUWBW01"; />
 <xsd:element name="E1WPG01" type="WPUWBW01.E1WPG01"; minOccurs="0"
 maxOccurs="9999999999" xmlns:xsd="http://www.w3.org/2001/XMLSchema" />
 </xsd:sequence>
 <xsd:attribute name="BEGIN" type="xsd:string" fixed="1" use="required"
xmlns:xsd="http://www.w3.org/2001/XMLSchema" />
 </xsd:complexType>
 </xsd:schema>
Already I am using this Idoc structure in various interfaces also. If i edit the occurance of the this Idoc and import in External definition with same name, I feel it afffect mapping in other interfaces also.
Inputs are highly appreciated.

Hi. Iu2019m trying to do 1:n multi-mapping using bpm scenario. I use file to file. Input file consists of many records and then I want many record to be transformed into many file at target system. I follow step in http://www.riyaz.net/blog/xipi-1n-multi-mapping-using-bpm/. However, I have a problem when file is retrieved in to XI. It doesnu2019t create any output file.
When I look at SXMB_MONI, it shows u201CNo object type found for the message Check that the corresponding process is activated.u201D Besides, it shows error message "Unable to perform action for selected message" when i clikc at PE in SXMB_MONI.
I have check at many previous posts with the same error message but still couldnu2019t solve it. I already activate my BPM and check that status in SXI_CACHE = 0. There is noting left in change list of my IR and ID.

Hi,
Yes, thats the problem.
You are creating file from test tab of 1..N mapping .
In case of 1..N mappping in mapping Extra tags of messages are addded to the data.As shown here:-
Messages
 Message1
 MessageType
When you use this mapping to generate xml message then it will add additional tags for <Messages> and <Message1>, which is not correct. it should only have structure of you MT.
So remove start and end tag of <Messages> and <Message1> from your data file. Mentioned below in bold.
<xml......>
<Messages>
<Message1>
<MT_...>
</MT_...>
</Message1>
</Messages>
This should solve your problem.

Sami.

1:N mapping without using BPM -- IDOC to multiple files

Hi all,
I am facing a problem while sending multiple files,
I need to send files ( File1, File2 or FIle3) ...
I was able to successfully send the first 2 files and along with it the 3rd file is being created without any data... How to stop this file( either file2 or file 3 should be created) in creating..
I have done the sceanrio like this, )ALL the source and target files are XSD's imported)
In the Message Mapping Messages Tab
Source is AFS_DELVRY03 occurence is 1,
Target files
rootI8 occurence is 1,
rootI9 occurence is 0...1,
rootIB occurence is 0...1
I have done all the maping part , problem is all 3 files are being created(eventhough 2nd or 3rd has no data) , I need rootIB, either rootI9 or rootIB based on condition,
So any one has done the similar scenario, If please suggest me how to hadnle so that only 2nd or 3rd file should be created,
In Interface Determination i have selected the extended option also...
Should i do any specific handling in the Configuration part or should i create more than one mapping?..
U r suggestions are welcome and will be rewarded with points,
Regards,
sridhar

Venu,
Using a BPM, you can do the mapping / Split as needed and then send the files individually, using a Sens Step as needed. There are multiple ways in which this can be done with a BPM.
But, for a solution without a BPM, as the requirement is such that only 2 of the 3 target messages need to be created, multimapping would not work and the need for conditional routing occurs.So, this would require additional mappings.
The solution is either use a BPM or do the logic using Conditional Routing. Ofcourse the second solution requires 3 mapping programs , but you are avoiding a BPM which can cause a perfromance bottle neck.
If perfromance cannot become a bottle neck, then using BPM would make much more sense , but again it all boils down to the exact requirements and the feasibilty of the solutions!

Solved .. Thx every one .
Approache Used :
1. Created mapping with Change signature on target Message type(idoc) with 1..N Occurence.
2. Operation mapping with change Occurence on Target Operation(1..Unbounded) .
3. Used same Operation mapping in Interface Determination with 0..unbounded(Multiplicity).

Cons of using BPM
