How to make CRM data sources for delta capability?

Question

Hi All,
I know that the CRM data sources 0CRM_SALES_ACT_1, 0CRM_QUOTATION_I, 0CRM_SALES_ORDER_I have delta capability.
At present we are doing full loads daily but it has got some performance issues.So we are thinking to make these as delta loads.
Already some one has made a trail to make delta loads but not successful for some unknown reasons.
Could you please suggest me the steps to make these data sources delta capable both in CRM and BW systems?
As this is urgent...Please suggest ASAP.

Answer 1

Hi
Go thorugh Below the note: 692195
Summary
Symptom
There may be problems or issues related to data tranfer from CRM to BW.
Other terms
CRM-BW extraction,upload,initial,delta,full upload ,Sales Analytics,
Reason and Prerequisites
There could be errors in customization or program errors due to which
data may not be transferred or incorrectly transferred to BW.
Solutions
Question 1 : The Extraction from CRM to BW takes a very long time. What can be done? (Performance Issues)
Suggestion 1: Please implement notes  653645 (Collective note) and
639072(Parallel  Processing).
The performance could be slow because of the wrong control parameters
used for packaging.
You can change the package size for the data extraction.
Also note that changing the package size in the transaction SBIW
would imply a change for all the extractors. Instead, you could
follow the path in the bw system.
Infopackage (scheduler)    > Menu 'Scheduler'   > 'DataS. default data
transfer'   > maintain the value as 1500 or 1000(This value is variable)
The package size depends on the Resources available at the customer side
(The no of parallel processes that could be assigned =
1.5 times the no of CPU's available approx.)
Question 2 : On executing transaction RSA3 I get records but I find 0
records when I load data from BW request.(No Data Available)
Suggestion 2: First check if there are any entries in the table
CRMD_ORDER_INDEX.Only if there are entries in this table you can
extract records.
If this is not the case then,
It is possible that the user does not have sufficient
authorities for extraction of  the relevant objects.
Additionally, please review and implement the following notes
615670
161570
150315
618953
If you are in the release 4.0 then
To do BW extraction with the user please see that the following
authorization object exists(display mode is enough):
CRM_ACT,CRM_OPP, CRM_LEAD, CRM_SAO, CRM_SEO, CRM_CO_SE,CRM_CO_SC
CRM_CO_SA, CRM_CON_SE, CRM_CMP, CRM_ORD_OP,CRM_ORD_LP,CRM_ORD_PR
CRM_ORD_OE, CRM_CO_PU, CRM_CO_PD, CRM_ORD_PO
(all these objects are linked to transaction crmd_order).
Question 3 : The Deltas for my data source are not extracted . What can I do?
Suggestion 3: Please check the following.
Please Check if the services have been generated in transaction GNRWB.
If they are not active(not marked 'X' before their names) then activate
the services following the steps here.
Go to transaction GNRWB
Select BUS_TRANS_MSG
Select (on the right, the services) : BWA_DELTA3, BWA_FILL, BWA_queue
Press Generate.
Also check  for the following:
1. The delta should have been initialized successfully.
2. Confirm that all Bdocs of type BUS_TRANS_MSG
   are processed with success in SMW01.
3. If there are queues in SMQ1 with erroneous status then activate
   these queues.
   In Transaction SMQ1 if there are Queues existing with
   names beginning with CRM_BWAn (n is number) then
   activate these queues in the same transaction.
4.a)If required activate the datasource
    Go to transaction BWA5   > select the required datasource and
    activate.
4 b) The Delta may not be active ,activate the delta in BWA7 by
  selecting the name of the datsource and pressing the candle icon for
  'activate delta'.
5. In BW system
   Go to transaction RSA1   > modeling   > infosources   > select the
   infosource   > right mouse click on the selected
   infosource   > choose option replicate datasource
    Activate the infosource.
6. Go to the scheduler for the infosource   > select delta  in the
    update  >choose the option PSA only (in the Processing tab)
    > start immediately
Check the entry in the RSA7 in the OLTP(CRM system)
Question 4: How can I extract the fields, which are not provided in the standard  data source extraction .
Suggestion 4: Follow the steps mentioned below.
1. Enhance Extract Structure with the required fields. (Create & include
   an append structure to the extract structure via transaction RSA6).
2.a) Release the fields of the append  for usage. (  To do this, double
   click on the Datasource and remove the flags in the column 'Hide
   Field' for all fields of Append. )
2.b)If the new fields cannot be seen in the extract structure of
    the transaction BWA1 then change and save the datasource, and then
    activate it in RSA6.
3. Define your mappings in BADI (CRM_BWA_MFLOW) to fill these fields.
Goto SPRO .
Follow the path ->
SAP Implementation guide ->Implementation with other mySAP components ->
Data transfer to the Business Information Warehouse->
Settings for the application specific datasources (CRM)->
Settings for BW adapter->
Badi :BW adapter :Enhancement of datasources in messaging flow.
4. Replicate the new Datasource to BW.
5. Expand the Communication Structure in BW.
6. Maintain transfer Rules for the new Datasource.
7. Activate the trasfer rules and perform the upload.
Question 5:  I am unable to extract  user status correctly.What should I
do?
Suggestion 5 :Check the following notes
531875
616062
713458
700714
765281
Question 6 : What can I  do when the activity/Opportunity/Complaint
reasons(Code,CodeGruppe,Katalogart)  are not extracted.
Suggestion 6 :Check the following notes
481686
516820
603609
617411
711146
Question 7:Deleted opportunities are not reflected in BW.
Suggestion 7: Check the note 706327.
Question 8: How do you  activate the metadata?
Suggestion 8:CRM BW adapter meta data has to be activated first before
it is available in the system. You can use Transaction BWA5 to copy the
meta data for selected DataSources. You can reach the transaction via
the IMG maintenance 'SAP Reference IMG -> Settings for SAP Business
Information Warehouse -> Activate BW Adapter Meta Data'. For more
information, see the documentation on the IMG activity 'Activate BW
Adapter Meta Data'.  (Note 432485)
Question 9: I donot get any records for the delta upload of my attribute
datasource(s).What is to be done?
Suggestion 9: In case of attribute datasources, it is possible that the
entry for the GUID is missing in the table SMOXAFLD.
If , for example the datasource 0CRM_OPPT_ATTR is not giving deltas
then you can follow the steps:
1)If Delta process is active for the attribute datasource e.g.
     0CRM_OPPT_ATTR,  then stop the delta process in the BW
     system 
2) In the CRM system, Make the entry in the table SMOXAFLD
   for the datasource with the Key
   as  0CRM_OPPT_ATTR     GUID 3) Save the entry.Activate the datasource                           4) Check that the above entry is replicated in smoxafld_s also    after this.               5) Create a transport request manually for the following    object             R3TR   SMO4   0CRM_OPPT_ATTR    
Question 10: What do the status BWSTONESYS0 , BWSTONEUSS0,BWSTTECSYS0 and various other BW status mean ?
Suggestion 10: The BW status are used to extract system and user defined
status.
The BW status are defined in the customization settings in SPRO.
Check for-> Status Concept for BP/Product/CRM objects
Here goto-> Process user status You will find the documentation attached here for the user status. Going inside the transaction you will find the status groups USS0, ZIOP,ZMOP etc. The names of the various BW status are derived from this For ex. BW + ST+ One + USS0 gives the name of the field BWSTONEUSS0 or BWST + ONE + ZMOP = BWSTONEZMOP (Master opportunity values) (which means BWST + (status group name) + status object group name) Double clicking on any of the object groups will take you to the values that these status can have . For ex. BWSTONEUSS0 in your system can have values E001 ,E002,E003,E007 which will be shown in RSA3 as BW status values 1,2,3,7, respectively.
Similarly we have Goto -> Process system status (in SPRO). Here you can get the values for the system status in exactly the same way as BWSTONESYS0(Lifecycle status) , BWSTTECSYS2 (Error) etc. In RSA3 you get the names as BW status, To know which corresponds to which status here,Gotothe record list in RSA3 . Here goto Settings - Layout -Current . Right click -> Press Show technical field names . You will be able to see the BW status names and will be able to adjust the layout accordingly.
Thank you,
