10 Digit unique ID generation in SAP

Hi All ,

I have a requirement to generate 10 Digit unique ID similar to GUID whenever a call comes to my custom SAP application .

Can someone suggest how to generate 10 Digit unique ID in SAP ?

Please note CREATE_GUID function module will gives more then 10 digit hence i can't use it for my requirement Also i don't want to use number range for this process due to locking & performance issue .

    Hi Sandra ,

    It's not massively but it can be parallel with little bit high in frequency .

    Hi Matthew ,

    It must be 10 characters because this data goes to downstream third party system which has some restrictions.



  • Try to create Number ranges if it depends on year so that every year you have a unique combination of number use the FM NUMBER_GET_NEXT and try to generate a unique number and concatenate with the year and any other keyfield. This is the best solution i can see for your question.

    Hi! Try this:

      DATA lc_guid TYPE REF TO cl_abap_random_packed.
      DATA lv_seed TYPE i.
      DATA lv_guid TYPE p.
    CALL METHOD cl_abap_random=>seed
        seed   = lv_seed.
      CALL METHOD cl_abap_random_packed=>create
          seed   = lv_seed
          min    = 1000000000
          max    = 9999999999
          prng   = lc_guid.
      lv_guid = lc_guid->get_next( ).

      Integer is not enough. Max integer = 2147483647.

      cl_abap_random=>seed generate unique integer, after that I use seed for generate a 'unique' p.

    This class implements the basic version of a pseudo random number generator. It is based on the Mersenne Twister algorithm. This algorithm guarantees a high period length for the generated values, and ensures that values are evenly distributed when multi-dimensional data is generated.

    I found 2 interesting reads -


    If i understand correctly, because the period length is so high the chances of getting the same "random" number is minimal. Now if the OP uses this "random" number together with (say) Fiscal Year, it'll kind of ensure that the combination is unique.
