copy R3 requirement to IPC -- two forms together?

Hi,

Appreciate all the great answers from Dom, Andrew and others. I've learnt a great deal about IPC :-).

I have another questions: using transaction VOFM --> Requirements --> Pricing in R3, I can select a particular requirement e.g., 900, to view source. I noticed there are two forms together once I view routine 900:

form kobed_900.

....

....

....

....

endform.

form kobev_900.

sy-subrc = 0.

endform.

Would anyone be able to tell me why two forms here? we need reproduce the "pricing requirement 900", how do we deal with kobev_900?

Thank you in advance,

Yanhui
