Photos or icons do not display after system copy

URLs for icons from the Content Server are cached in INDX database table. After a system copy the cached files will still be in this table and therefore some icons do not show. Clear the cache using these instructions to resolve:

1. Implement SAP note 1791965
2. In transaction SE24 enter CL_HRTMC_GRID_FACTORY_UTILS and click Test (F8)
3. Execute method REFRESH_GRID_REPOSITORY

The content of this cache can be seen if a breakpoint is set at the beginning of method IS_IN_STORAGE of class CL_HRTMC_GRID_FACTORY. Here the whole table of URLs is imported. The cache entries are never cleared unless method REFRESH_GRID_REPOSITORY is executed as per the instructions above.
