Hi Amitav,

Hi Amitav,
This is a tricky one.
There is a field that it set within SAPMV45A processing (r185d-dataloss) which is set to X if a standard SAP field hase been changed in the order.
So, here is what I would suggest you do:
1. set up your output condition type as 'multiple issueing'.  This will ensure that every time you go into change a sales order the output type is proposed
2. In the userexit USEREXIT_SAVE_DOCUMENT_PREPARE I would export to memory (using the sales order number as the key) the value of r185d-dataloss
3. In your requirement import from memory the value of the field r185d-dataloss (clearing the memory entry afterwards)
4. If the value is X then pass the requirement, otherwise fail it
This way, your requirement will always reject the output type until the document is saved.  If it is saved and there were changes, during update processing the requirement will pass and the output will be generated.
If you want to avoid IMPORT/EXPORT from memory then you could use the technique described in my blog: /people/brad.williams/blog/2005/04/25/userexits--how-do-i-access-inaccessible-data
Hope that that makes sense. 
Cheers,
Brad
