Interview Question about VKOA

Hi All,

I have couple of questions about FI-SD 'Account Determination' using T. Code - VKOA that I need help with urgently.

1. Does any one know what 'Account Key' (ERS, ERL etc.) should be used for a G/L Account pertaining to "Research and Development (R&D)costs" in VKOA configuration?

2. Also, in VKOA configuration, for this R&D G/L Account should we use Condition Type – KOFK (or, it should be set with KOFI)?

Thanks in advance.
