- SAP Managed Tags:
I got a chance to work on SAP Demand Signal Management for one of the customers where we loaded IRI Market Research Data into DSiM. If you belong to BW background working on DSiM can be a bit overwhelming, because although it seems like its simple BW, there are a lot of concepts associated with DSiM that one needs to understand. Resolving errors can be a daunting task and you might feel stuck at times. I have consolidated here a list of all the issues I faced and how I went into resolving those. The version of DSiM that I was working on was DSiM 3.0
While loading data to /DDF/DS15 (Time Propagation layer DSO), the data load fails with the error above. Issue is because 0DATE_MMTT infoobject is obsolete now. And so we need to reinstall the DSO /DDF/DS15 and the required infosources and transformations.
As shown in transformation above the infosource still contains old Infobject 0DATE_MMTT. So reinstall the InfoSource /DDF/MD_TIME_15_I and the transformation from standard BI content. Once reinstalled, the transformation looks like below :
For more details look at the following OSS Note :

f you want to customize the mapping of any of the fields from CSV Files to the BW datasource, you can define a BADI for mapping enhancements in SPRO.
Below is a sample code which has to be written in the method GET_EXTR_FIELD_VALUE.
As shown below I have split the product field from the file at space and taken the entire string except the last part. Similar to this you can apply other transformations to the file data.
In order to debug this custom code written in the BADI,
Go to RSA3 and enter the extractor name and put the delivery ID, process ID and DDA from the info package or PSA and run the extractor after putting breakpoint in the badi code.

DATA: ls_source_data LIKE LINE OF it_source_data.
TYPES : begin of ty_str,

end of ty_str.
DATA: it_str type table of ty_str,

lv_index type sy-tabix.

ASSIGN COMPONENT 'DATA' OF STRUCTURE ls_source_data TO <product_ext>.

lv_index = lv_cnt.
read table it_str into wa_str index lv_index.
cv_extract_value = wa_str-str.
ENDCASE.
ENDIF.
endmethod.
Sometimes while loading master data you may realize that the products are getting loaded in the acquisition and propagation layer DSOs i.e. /DDF/DS41 and /DDF/DS51, but you cant find the same product in /DDF/PRODUCT.
In our case we were using Direct update to update the data in the Infoobject /DDF/PRODUCT.
So the first thing to check here is check the logs for the Direct update program (/DDF/BW_MD_UPD ) in the Job Monitor to see if its running successfully or if it has any errors.
In our case the job was running fine and did not have any errors.
So we ran a program /DDF/FDH_SELECT_FOR_CHGLOG to add these product entries to the Change log table of harmonization table.
After this rerun the program /DDF/BW_MD_UPD in order to see if the entries are updated.
The source products should be available in /DDF/PRODUCT now.
Sometimes while setting the File Naming Pattern, the system might throw errors and its difficult to understand exactly what is allowed while setting up the naming pattern.
Wild Characters are represented using + and any number of wild characters are allowed as long as they are together. Also the file name can contain letters, numbers, underscore but hyphen is not allowed.
This class(/DDF/CL_ADU_FILE_TOOLS) and method (CHECK_FILENAME_PATTERN) shows the checks that the system performs for the File name mapping. You can put a breakpoint to check if you are still getting error in the filename pattern.
Lot of times you want to cancel a process from running but the cancel button is disabled in process monitor.
In that case you can go to SE38 program /DDF/ADU_CANCEL_INSTANCE
You can check the delivery ID from the manage tab of the DSO.
This is an system issue. Although we are not using the Consolidation Layer for Time Master data the system still checks the Consolidation Filter which is not correct.
The correction should be applied as mentioned in the below OSS Note:
https://launchpad.support.sap.com/#/notes/2870378
After resolving the errors above, We were able to load the market research IRI data successfully into SAP DSiM. I would like to thank my colleague guilherme.costa4 for his help and guidance throughout the project. We also worked on the integration of SAP DSiM with CBP. I will be publishing another blog to talk about this integration part.
I hope this blog is helpful for everyone working on DSiM.
