Knowledge Management

Question:
All,
I am trying to validate an account document created from a web application before posting it. I am unable to find a fn module, BAPI or program which accepts the document information as an input and perform the validations and returns the errors back.
I found a few Fn modules like API_ACC_DOCUMENT_CHECK, but they do not perform the validations in validation/substution nor they have fields for profitability segment (or atleast I am unable to figure out how to populate them).
Have anyone been in a similar situation or know how to do it? Any help will be appreciated..
Thanks

Answer:
The term for such an activity is "simulate". Check function modules related to the documents you want to check, of which the name contains "simulate".
