Dear Nick
the "Status" on specification hearder is used rarely in the context of WWI. First I recommend that you should read the onlien SAP help (and how data is retrieved in WWi report based on Status).
The topic is "very complex" it belongs to scenarios not easy to understand in context of WWI
The topic is most worse as you seem to use "change numbers"
I have never seen such a "complex" scenario; at t is not easy to explain the "relations" between WWi, Status, and Change numbers.
May be check: WWI for Experts
and e.g. this link:
Generation Not Permitted - Basic Data and Tools (EHS-BD) - SAP Library
It is very imprortant to understand the relation of data maintained on spec level and the definition of the generation variant.
May be check:
Generation Variant - Basic Data and Tools (EHS-BD) - SAP Library
So it is very difficult to explain to you all the "relations" if you are using at the same time:
"Change numbers"
and "Status"
This combination is very tricky in relation to WWI reports; personally I have no experience.
Please read first the SAP help; may be you get a clue how it worksit takes a lot of time to really understand it !
Regarding use of "Change numebers" may be read:About use of Change numbers in SAP EHS Management (Classic)
My recommendation would be: try to simplyfiy your maintenance approach; your approach is very very tricky (and is really not easy for endusers as well)
