Object activation taking too much time


In our SAP instance (760 release) at work activation time is taking too much time. Around 10s for a Z program, if we need to activate more than 3 objets simultaneously it takes more than 30s to do so.

I tried debugging the activation, and from what I noticed the longest part of the treatment is done in the method :

cl_wb_crossref->select_index. In this method there is a selection done on wbcrossget that retrieves nothing, still, it takes a lot of time to load.

When I checked, this table contains more that 12 million entries.

I tried running SAPREUB et SAPREUC programs but it's taking forever, it treats respectively 500entry/h, and ~75 entry/h.

This note 2039618 talks about recompiling WBCROSSGET, but I don't know the impact of deleting the table first.

Did anyone encounter this problem ? Or knows how to solve it ?

Thank you very much,

    Well, obviously no one had the answer or didn't bother.

    I managed to find a solution :

    • Run EU_INIT job
    • Refresh statistics of table WBCROSSGT in DB20

    That solved my problem.
