    Hi,

    Thanks for your answers.

    So, If I set up period to evaluate 3 and period type M, the statistical data from st03n will be moved in every 3 month to the solution manager database table with the usage information?

    If I set up 1D, then the data will be transported in every day?

    If I schedule the CNV_CDMC_CA_COLLECT_STAT_700 job (I think this job collects information from st03n) on every week (1W), in this case, these collected information cannot be transported to solution manager in every week, but these information will be collected in cdmc database table in the managed system, and according to the period to evaluate and type these data will be imported to the solman.

    Is this right only in case of CNV_CDMC_CA_COLLECT_STAT_700 job or any kind of job as well (I am thinking about CNV_CDMC_CA_COLLECT_TAB_STAT and CNV_CDMC_CA_EVAL_SHORTDUMP)?

    If I execute a CA project, this project will be updated according to the new information or not, and I have to create always a new project?

    It is not clear for me. Can you clarify please?

    Thank you!

    Best regards,

      Hi Zsuzsanna,

      ST03N can store the statistics as per the settings done in the managed system. It is not like it will only store the information for 3 month it can be even more than that.

      In CDMC while activating the statistics collection in the 'Global Settings' phase if you give time frame period as 1 months then it will take statistics from ST03N and will store in CDMC table.

      You can also give time frame more than one month but you should make sure that this statistics available in ST03N first.

      There is no deletion for the table which stores the statistics information in the managed system.

      Please let me know if this is clear or not ?

      You can also give some points if found the given answer helpful.

      Best Regards,

    Hi,

    This is the default settings, where system collects the last 3 months data from st03n and move to cdmc tables, it also depends on st03n data, if your st03n has 2 month info then, the first run of statistics jobs hold only 2 months data for analysis. Due to regular monthly statistics collection,CDMC can hold more than 3 months data for analysis.

    We had wonderful discussion on this, check out

    also review the latest note 1478324, question 6.

    Thanks

    Hi Zsuzsanna,

    In transaction CNV_CDMC when user executes activity 'Activate Statistics Collection' in the Global Settings phase, You can see the first pop-up screen 'Maintain Systems For Statistics Collection' after entering the statistics system once click on the activate Icon you get the following pop-up screen:

    Here Period to evaluate and Period type is to give input for what period you want to get the usage data for the customer objects for that particular statistics/production system. Here in the screenshot you can see input given as 3 and period type is M which is stand for months ,similarly you can also give it with the number of Weeks and Days.

    While scheduling the banckground jobs to collect the statistics data and store it in the CDMC database table, it will take this input and for the same period it will collect the usage statistics from the standard transaction ST03N.

    In this example it will collect the usage statistics for the 3 months that is for past 3 months.

    You can also refer SAP Note 1316694 for more information.

    Best Regards,

    Pritish
