Adjustments in production systems

Hello,

I work on SAP Product Support. There are a couple of incidents opened by customers related to high amount of dumps when changing their production system during business hours. My goal with this post is to share some information about causes and solutions related to this topic.

There are several types of dumps that may occur in such scenarios. Some of them are listed below:

  • DDIC_COMP_CNT_INCONSISTENT
  • DDIC_TYPE_INCONSISTENCY
  • DDIC_TYPELENG_INCONSISTENT
  • GETWA_CANT_CLEAR
  • GETWA_WRONG_LENGTH
  • LOAD_COMMON_PART
  • CONNE_IMPORT_WRONG_COMP_TYPE
  • LOAD_CLASS_VERSION_MISMATCH
  • LOAD_INTF_VERSION_MISMATCH
  • LOAD_PROGRAM_CLASS_MISMATCH
  • LOAD_PROGRAM_LOST
  • LOAD_PROGRAM_INTF_MISMATCH
  • LOAD_SWITCHSTATES_MISMATCH
  • LOAD_TYPEPOOL_VERSION_MISMATCH
  • LOAD_TYPE_VERSION_MISMATCH
  • TYPELOAD_NEW_VERSION

Be careful when executing the following activities in production system:

  • Activate business functions
  • Release transport requests into a running system
  • Convert database tables
  • Make changes to programs or dictionary elements that could affect programs that are currently running

It is recommended that a window be defined when doing such adjustments. If it is not possible to stop the system, it is recommended that such adjustments be done when few user are using the system, for example on the weekend or at night. However, the ideal scenario is that nobody be connected to the system.

In case you start getting the dumps mentioned above, it is recommended that you check the solution described in the following note:
162991 - Generation tools for ABAP programs
