Dear AnnChristine
in last year a lot of changes happened in WWI enivronment. Some of these can be used only if you have proper SAP version in place. You should always check the OSS mentioned by Mark (and I believe inside that you will get always reference to OSS for current WWI version)
Especially regarding WWI: currently roughly two SP WWI versions are dispatched by SAP per yeat. Some of these version contain only corrections; but some of them add functionality.
You need always to be carefuly: how you would like to use SAP EHS? Do you use SAP EHS GLM? Yes / No?
Especially with Enhpack 7 huge changes happende in the SAP internal framework; and some of these changes have had impact on WWI development.
Best practise:
On SAP marketplace you will find here only some "hints/Advices" by SAP /e.g.together with a WWI sizing guide).
E.g. now WWI has been improved a lot for e.g. multithreading on Server etc. etc. Most of them set up issues are raised in collaboration: which windows version to use? which winword version to use? which access rights must be granted to windows user running WWI etc. etc.
May be check: WWI for Experts
Here you will find some refrences to the many threads discussing WWI set up (and challenges there in e.g. RFC connection, WWI administration),.
If you check document SAP EHS Management for Beginners
you will find this comment by a SCN user regarding WWI:
"Just to throw in my two cents worth. With regards to installing Windows services for the EHS Expert Server and WWI Server: one needs a pretty good knowledge about Windows administration as well (service administration, windows policies, event log etc.). So, you probably need an admin guy that takes you by the hand and guides you through the whole installation procedure."
Based on reasearch in SAP marketplace. a number of OSS corrections are in place for WWI and related stuff in the last 6 month. Some of them are worth to look at and to install them.
