Initial load in middleware

Hi,
When i start the initial load with transaction R3AS, after specifying the load object and destinations on execution it throws me an error "NO GENERATION PERFORMED CALL TRANSACTION GN_START".
I tried running GN_START transaction, after completion of that, when i again try R3AS, it shows the same error again. ("NO GENERATION PERFORMED CALL TRANSACTION GN_START".)
Please suggest some ideas.
Thanks & Regards,
Karthik.

Hi Karthik,
Start transaction GN_START to generate the missing objects. The status of the generation (generation errors) can be seen in transaction GENSTATUS.
Regards.
Manuel.

Initial load of BP through Middleware

Hello,
I try to do the initial load of Business Partners from R/3 into the CRM system. The monitor displays, the load has been done succesfully (green light), but no business partners appear in the CRM. Can someone help me?
Points will be awarded
Thanx, Peter
btw: does anybody have some document about setting up the Middleware to transfer data from R/3 to CRM and vice-versa?

Peter, before you can load the BP from R/3 to CRM you need to do some mandatory configuration which - on high level - are:
1 - Map BP Master Data from R/3 to CRM
2 - Map BP Master Data from CRM to R/3
3 - Synchronize field settings between R/3 and CRM
4 - Configure field attributes
5 - Execute actual BP replication
For details on how to execute these configuration stepse steps have a look at http://help.sap.com, select here SAP Best Practices -> Cross-Industry Packages -> CRM. In the CRM Best Practices select Business Information and Preconfigured Scenario's, select (ob right hand side) a sales related scenario, e.g. Internet Sales and select Building Block B09: CRM Replication. In the actual Building Block navigate to page 45 and execute the steps accordingly. Hope this helps, Tiest.

Middleware starts replicating before initial load

Hi folks,
currently i´m setting up the middleware to connect a live ERP with a fresh CRM. The initial load is not done yet, also a lot other configuration stuff. I noticed that at the time of registering the queues the middleware is connecting itself and listing first BDocs in SMW01. Mostly R3AD delta(!) material BDocs (which fail by mapping error currently) but also green ones like 'class message' or 'objcl_message' which seem to have dummy or real entries. This is a problem as i did not configure e.g. R3AC1 filters or number ranges yet.
I thought delta load is triggered first after initial load. How can i stop the middleware before i finish the configuration stuff. If there is a 'switch off' (like deactivate a business adapter object in R3AC1) i guess i would have to switch it on again just before the initial load and then risking uncontrolable connection againg before i can execute R3AS. I mean if i would e.g. deregister the queues i could end my configuration but i would have to register the queues just before initial load and would again having no control about the start of the replication. Is that a problem for you? - How do you handle that issue usually if you set up a new CRM?
Thanks

Middleware - Initial Load problems

When I try to do initial load for DNL_CUST_ACGRPB from R/3, the status is 'Running' for long time and does not change to 'Done'. How to troubleshoot the problem and can someone help in resolving this issue?
thanks a lot in advance.
Sam

Sam,
Have you looked for any failed queues in either R/3 or CRM? Check SMQ1 in R/3 and SMQ2 in CRM. You should also see if the queues are registered in both systems, via SMQR.
For CRM:
Did you properly define your R/3 site in SMOEAC? Have you tested the RFC destination to R/3? Does the R/3 user have full security?
For R/3:
Did you check the settings in CRMRFCPAR? Does the RFC destination work correctly. Does the CRM user have full security?
For an object such as the customizing downloads, like DNL_CUST_ACGRPB normally the error surrounds your CRM setup between the two systems. If all those steps are workly correctly then you will need to consider a few other options.
Also you will need to do the following in CRM before you try loading again:
1. In R3AM1 hit the abort button on the object.
2. In either SMQ1 on R/3 or SMQ2 in CRM, delete the queue that failed.
3. Fix any configuration issues with your middleware setup.
4. Execute the initial load again for the object.
Good Luck,
Stephen

Middleware Question - Initial Load vs. Synchronize

Is the initial load (transaction R3AS) of an adapter object required for replication to be carried out from R/3 to CRM? Can I synchronize (R3AS4) instead if I don't need the existing data?
Also, is it even required to do some sort of action (either initial load or synchronize) before we can start replicating?
Our issue is that some items that are under a certain adapter object aren't replicating and I am guessing that I need to either do the initial load or synchronize it. Is this correct?

Hi,
pl check entries in R/3 Table in SM30
1) Table CRMRFCPAR... Here check CRM FILTERING ACTIVE
2) CRMSUBTAB : In this table check for subscription upload and downlod objects
3) CRMRFCPAR : In this table RFC Destination , you define object and load type ( whether intial load or delta load etc..)
4) CRMCONSUM: In this table , define possible user of R3 adaptor functionality.
After this you can do In CRM in Transaction R3AS ( initial down load ) the delta download.
In CRM ,You can also do the filter settingf for the objects in transaction R3AC1 ( ADAPTOR object filter settings ) if required , similerly check entry in transaction R3AC3 and R3AC5

Middleware initial load error on funcloc segment type (ADR2) does not exist

Hello,
We are doing initial loads of data into a new CRM 7.0 system.
So far all objects have been done except Functional locations (FUNCLOC).
During the initial load of the functional locations the various BDOCs all go into error state.
The error is the same everywhere: segment type adr2 does not exist.
If we deactivate the adr2 table In transaction R3AC1 and process again, we get the error message for the next table
(Like: segment type IFLOTX does not exist) and so on.
IS there any settings we can do to manage these 'segments' or would there be another wa to solve this?
Thanks.
Joram

Hello,
Take a look at note 1271465, it does not talk about the ADR2 segment but about segment errors in SMW01 for functional location download. It might be useful. Observe especially the constraint in ERP version number, it might be that your ERP system is out-of-date/incompatible for this scenario.
Second thing to check, go to SPRO>CRM>Master Data>Installed Base>Replication of technical objects from ERP
There you'll find a mandatory customizing activity for Functional location download.
And in the documentation of activity "Replication of Functional locations: Prerequisites and General information" you'll find all the necessairy actions to perform.
This helped me in setting up funcloc replication in CRM 7.0.
Hope this helps,
Kind regards,
Joost

Debug Middleware Initial Load

Hi Experts,
How do I debug initial load data? I am uploading data from R3 to CRM. Some of the set types data is missing. How do I debug to find out why some set type data is being uploaded successfully where as some data is not related to an equipment(installed base).
Regards,
Abdullah Ismail.

Hi Shalini,
I have put an external break point in the specified badi but it does not stop there. There is some issue with the initial load and queues. When I unregistered the queues and execute r3as, all the queues get registered. Hence debugging does not work. There is some problem with the delta load also when the equipment is changed in the R3 side. The functional guys are trying to fix it up. Hopefully it finishes soon and I get to award you points
Regards,
Abdullah

Middleware initial load in production

We have a question over how to run an initial load (R3AS) in our production system. We have over 4 million business partners and 9 million contract accounts that will require replication from ERP to CRM system. We expect the initial load could take several days to run. Is there anyway to stagger the initial load? This is due to that we may not want replication activities occurring at certain times of the day. We'd like to just do an initial load on a range of bp's per day. It seems this could be accomplished by setting a filter, but my understanding is that as we shift the filter, we would then be missing the deltas of the previous bp's that were loaded via initial load. Is there anyway to accomplish a staggered initial load? or do you need to basically fire off the initial load for your entire filter.
Does anyone also have any tips that are geared towards replication as it relates to large volumes of data.
Pam Crissman

Pam,
"It seems this could be accomplished by setting a filter, but my understanding is that as we shift the filter, we would then be missing the deltas "
You can activate the deltas manually in R3ac4.

No initial load of Customers, Material and delta load of Sales Orders.

Hi Experts,
I am facing a very troublesome issue. I am not able to setup the Middleware portion for initial and delta loads. I read a lot of documents and corrected a lot of things. finally, the connectivity is done with R/3 and CRM. Initial load of all objects is successful (as per Best PRactices guide). Customizing load is successful.
But after now I have these open issues for which I am unable to find any answers (am really exhausted!!):
- Customer_main load, it was succesful, but no BP's of R/3 are available.
- Material, it failed in SMW01, SMQ2, the errors are:
Mat. for Initial Download: Function table not supported
EAN xxxxxxxxxxxxxxxxxx does not correspond to the GTIN format and cannot be transferred
EAN yyyyyyyyyyyyyyyyyy does not correspond to the GTIN format and cannot be transferred
Plant xx is not assigned to a business partner
- Sales order, it shows green bdoc, but error segments says "No upload to R/3" and the order does not flow to R/3.
We had our system setup 3 years back for data transfer and Middleware. But few things changed and connectivity stopped. I did all that again now, but am not yet successful. Any inputs will be greatly appreciated.
Thanks,
-Pat

Hi Ashvin,
The error messages in SMW01 for MAterial initial load is :
     Mat. for Initial Download: Function table not supported
     EAN 123456789000562 does not correspond to the GTIN format and cannot be transferred
     EAN 900033056531434 does not correspond to the GTIN format and cannot be transferred
     Plant 21 is not assigned to a business partner
I have done the DNL_PLANT load successfully. Why then the plant error?
Some of the messages for BP:
Messages for business partner 1331:
No classification is assigned to business partner 1331
For another,
     Partner 00001872(469206A60E5F61C6E10000009F70045E): the following errors occurred
     City Atlanta does not exist in country US
     Time zone EST_NA does not exist
     You are not allowed to enter a tax jurisdiction code for country US
     Validation error occurred: Module CRM_BUPA_MAIN_VAL, BDoc type BUPA_MAIN.
Now, the time zone EST is assigned by default in R/3. Where do I change that? I do not want to change time zones as this may have other impacts. Maybe CRM I cna change this, not for sure in R/3. City check has been deactivated in R/3 and CRM, still the error.
Till these 2 are not solved, I cannot go into the Sales order loads.
Any ideas will be greatly appreciated.
Thanks,
-Pat

Error while Initial load

Hi Forum,
Iam doing Middleware setup for downloading customer master from R/3 to CRM.Iam trying to do initial load of customizing objects viz.,DNL_CUST_ACGRPB,DNL_CUST_ADDR,
DNL_CUST_KTOKD,DNL_CUST_TVKN,DNL_CUST_TVLS,DNL_CUST_TVPV... which are to be loaded before doing initial load of CUSTOMER_MAIN.
while doing initial load of customizing objects iam getting the below mentioned error
001 No generation performed. Call transaction GN_START.
002 Due to system errors the Load is prohibited (check transaction MW_CHECK)!
-when I do GN_START
"A job is already scheduled periodically.
Clicking on 'Continue' will create another job
that starts immediately.
Do you want to continue?" message is displayed
and I have sheduled it.
But in SMWP transaction I can see in
BDoc Types: Generation of other runtime objects
Not generated / generated with errors 2 entries
 31.08.2006 05:33:50
and the objects with errors are
POT_LISTWRITE
SPE_DDIC_WRITE
-In transaction MW_CHECK, system displays message as No generation performed. Call transaction GN_START.
when I regenerate these objects(generated with errors)from the context menu I find no difference.
I have also referred to the Note :637836 and 661067 which also suggests to run few reports and GN_START but inspite of doing all the corretion parameters in the note Iam still unable to come out of the situation.
Please Guide
Thanks in Advance

Hi Rahul,
Thanks for the reply.I checked in transaction MW_CHECK and the system throws the message as
No generation performed. Call transaction GN_START.
In the long text the below message is available
No generation performed. Call transaction GN_START.
Message no. SMW_GEN_KERNEL005
Diagnosis
An upgrade was performed.
System response
The Middleware is stopped because MW objects must be generated.
Procedure
Excecute transaction GN_START.
If GN_START is executed,I dont find any change.
I also checked in smq2in CRM and I found the status of the queue as below

Initial Load Error - No generation performed. Call transaction GN_START

Hi Folks,
We are doing middleware configuration for data migration between R3->CRM.Have followed "Best Practies" configuration Guide.
System Using; CRM 2007 and ECC6.0
Issue
While performing initial load, system is throwing the error as
001- No generation performed. Call transaction GN_START
002-Due to system errors the Load is prohibited (check transaction MW_CHECK)!
After calling the transaction GN_START system asks for job scheduling,whereas I have already scheduled it.
A job is already scheduled periodically.
Clicking on 'Continue' will create another job
that starts immediately.
After checking(MW_CHECK),message is displayed as
No generation performed. Call transaction GN_START.
If anybody has encountered the similar issue and has resolved it,their guidence will be greatly appriciated.
Thanks in Advance
VEERA B

Veera,
We also faced the same problem when we have done the upgrade from CRM 4.0 to CRM 2007.
For that you go to SMWP where you can see all the errors related to Middleware with the error message so try to remove the error,
Also pls check in RZ20 and activate the middleware trace tree.

Hi You Nakamura,
We are facing the same problem during AS ABAP - initial load with the same error message.
I downloaded the msvcp71.dll file and placed it in System32 folder. But the problem remains the same (even after server restart).
The system log shows the same error message and no entries in job log.
Please let me know if you had followed any different way to install the dll file.

SYSFAIL in Initial Load of BUPA_MAIN

Hi Colleagues,
We are performing an initial load from a IS-M solution, so we use BUPA_MAIN instead of CUSTOMER_MAIN.
We have some BDocs that present problems in this load, but it has been preventing the queue R3AI_BUPA_MAIN from being processed. It stops with SYSFAIL with message "Error in Mapping: Detais trx. SMW01).
We expected that initial load shouldn't stop at any BDoc with error. We expected that we could just solve those BDocs with trx SMW01.
And there's something else. I've seen in other project that if Middleware detects an error in a BDoc block, it just split the entries with error and process the correct entries. In our case, if one entry is wrong, all entries keep in the BDoc, including those that has no error at all.
Is there normal behaviour or is there a parameter that control its behaviour. In simple words what we need is:
1) BDocs with error are dealt in SMW01 but don't stop the queue, preventing all other BDocs from being processed.
2) A block of BDoc is split when some of its etries have an error, allowing the other entries to be processed.
Best regards,
Renato

Here is the best answer I got:
the u201EError in Mappingu201C issue happens at a very first moment of the data flow when the data is just coming into CRM Middleware and there is still no BDoc created. This happens often when there is a problem, i.e. with the table definition, in transaction /nr3ac1. When you have a single queue handling then this problem will only stop the queue related to this BP. If you have reduced queue names or mass queues it will stop the queues, indeed.
The procedure you are describing regarding the handling of errors (processing the good ones, and keeping the bad ones) is available since CRM 4.0. I do not know a single parameter where you can switch on or off this behavior.
Please have a look for parameter MAX_QUEUE_NUMBER_INITIAL. Hope you will find the correct note.

SRM Initial Load

Hi Experts,
I am doing an initial load from ECC to SRM. The middleware parameters have been configured according to the OSS msg 720819. I start the load using R3AS for object DNL_CUST_PROD0. In R3AM1, I see the status as waiting and the BLOCK size is ZERO. Nothing is getting replicated from ECC into SRM. Any help would be highly appricated. We are om SRM 7.0 with ECC 6.0.
Thanks

Hello,
you need to add new entry in SRM SMOFFILFLD table with SM30 transaction:
Then, new field will be able among table filters in R3AC1 transaction.

Error during initial load of object SI_CONNOBJ

Hi All,
I am not able to do initial load of object SI_CONNOBJ from OLTP R/3 to CRM using transaction R3AS. It is in "Abort" Status. When I am checking the relevant Bdoc generated for the same it is giving me the error as "No data records in transport structure BAPIMTCS Message no. IBSSI_CRMTO_MESSAGES010 ". Please help me in this regard.

Hello Aishuman,
I am not sure what your question is. Yes, of course, you must have connection objects in the IS-U system. Otherwise, what do you want do download to CRM? You must have have the middleware in general and also the adapter SI_CONNOBJ enabled in the IS-U system. I am sure you know, that an IS-U connection object is represented as an IBASE in CRM.
Does a delta replication work (from IS-U to CRM and from CRM to IS-U)?
Kind regards,
Fritz
