EG42 - Device Modification Prorate time slice

Question

Hi SAP Experts,
User changes the register group using EG42 and click on prorate as well, which creates the time slices in the system. User do not want those time slices. We have asked user not click on prorate, however they are still doing it by mistake.
Also, sometimes they do this when device is in AVLB status which creates weird time slices.
Currently to correct those timeslices, we change the table entries in EGERH, EADZ, ETDZ, EASTL, EASTS. But we need a permanent solution for this issue:
1) How to stop user from clicking prorate, can we disable the option or is there any config?
2) Is there any transaction which can reverse this activity, as in change the register group back to original and remove extra timeslice?
3) Is there any EXIT which can give user an error when they click on prorate?
Please advise.
Regards,
Nidhi

Answer 1

When user changes the register group checking Prorate, there can be three scenarios:
1) Number of registers in new register group are less than number of registers in original register group
- I am not able to reverse these and need to change table entries in ETDZ, EADZ and EASTS. How to reverse/remove such time slice using EG42 or any other transaction?
2) Number of registers in new register group are greater than number of registers in original register group
- These can be reversed by just using EG42 and changing the register group back to original.
3) Number of registers in new register group are equal to number of registers in original register group
- These can be reversed by just using EG42 and changing the register group back to original.
