tcode SE80, click “Display Detail” button to view the detail of this ATC error:

We can find the class CL_CRM_SFW_EHP3_SWITCH_CHECK is exposed via package interface CRM_SFW_EHP3:

goto tcode SE80 and open package CRM_UIU_RO_CI, and this missing package interface:

then try to add CRM_SWF_MAIN into parent package CRM_UIU_RO:

go back to CRM_UIU_RO_CI, click button “Copy from Superpackage”, ensure package interface CRM_SFW_MAIN now also appears in the Use Accesses list.

重新执行ATC check后error消失.
