However, After activating it is not possible to add the shift related sub screens number 0240, 0930, 0430 in the customizing of the single screen entry confirmations. The system gives following error messages:
Entry 10 E 0430 does not exist in VCORUSSVAL (check entry)
Entry 10 E 0930 does not exist in VCORUSSVAL (check entry)
Entry 10 E 0240 does not exist in VCORUSSVAL (check entry)
And return with message no 00058.
The root cause of the issue is solved by SAP note 1306409 and solution is given step by step in SAP note no 1415590 in which you need to maintain the translation for domain EHP3_RU_DT_DYNNR for these sub screens after that they are available in OPK0.
If you wish to use this shift related confirmation functionality , then please check SAP Note 1306409 and 1415590 which are valid for enhancement package 4(SAP_APPL 604).
