Hey Markus,
what exactly do you want to add there? VICDCOND, VICDCONDCALC, VICDCONDDIST etc. are tables for conditions from the contracts and the rental objects. They will be updated automatically when changing condition information in the contract or rental object at the time you click on save button.
I do not know any non-modification method how to add data in table VICDCOND. There is no Customer Include structure for table VICDCOND, these are only for branch data tables like VIBDRO (rental objetcts) or VICNCN (contracts). Even if you try to add fields in table VICDCOND with APPEND, I think there is no way how to get them automatically filled and I would not advise you to try it ;-)
CONDGUID is the unique identifier for every condition, its a hexa-decimal value that identifies every condition, like PARTNERGUID for business partners.
Why do you need new fields? If you want to have your conditions in a list, you can use SAP standard transaction REISCDCN which you can enhance with BADI.
Regards
Michael
