Problem of configuration the requirement output control ?

Question

Hi ,
i am now in a very urgent situation that is the system does not create the message type after executing the transaction VL31N.
In detail :
   I have used the transaction NACE to configure the "Requirements output control" and i have created 3 message type (Z1 , Z2, Z3)  ( type V6 : handling unit) and i have coded for each of them to check the requirements for creating the messsage type ( the message type will be created if the sy=subrc = 0 after the forms are executed.
FORM KOBEV_Z1.
Check condition from the structure  komkbv6
if cond Ok
  sy-subrc = 0.
endif.
ENDFORM KOBEV_Z1.
  FORM KOBEV_Z2.
Check condition from the structure  komkbv6
if cond Ok
  sy-subrc = 0.
endif.
  ENDFORM KOBEV_Z2.
  FORM KOBEV_Z3.
Check condition from the structure  komkbv6
if cond Ok
  sy-subrc = 0.
endif.
  ENDFORM KOBEV_Z3.
But in fact , even if i have put the sy-subrc = 0 for each of them or for all , the message type was not created as i need .
Result :
  if the message type is created automatically after executing the KOBEV or KOBEV , a printing program will be called to print the SAPscript form , but till now , i can not do that , to print the form i have to created the message type by hand ..
Is the something wrong in the system ? How can i configure them to run well ?
Please help me .
PS : I will reward immediately and i am waiting
Thank you very much

Hi,
If you are supposed to bring across characteristic values to your target, then you will not be able to jump from the result line. The configuration expects that the values of the characteristic marked as being used in the jump are filled with unique values. When you use the result line as a source for your jump, the values in the result line will most likely be based on the sum of multiple characteristic values.
