hi dear experts

i am a newcomer in sap hcm module.

our company wants to implement ess and mss through nwbc.

i used transaction /nnwbc to run ess and it showed me the ess page successfully but whenever i click on any of links in the page it shows me this error:

""""Service cannot be reached

i have activated icf and webgui through sicf transaction. now i don't know what to do more please help me what should i do?

also i have read somewhere that we need to activate HCM_ESS_WDA_1, HCM_ESS_WDA_2, HCM_ESS_WDA_3 business functions. is it true?

Hi AF

You System admin will need to use transaction SICF to activate each service (including the Webdynpros)

I usually sit in Chrome and press F12 to look at the URL being called to find the service to activate

Configurations guides will normally call out the list of services needed for Business Client functionality for the module/functionality you are doing.

In short, you have more SICF activations to do.

Dear Colleen Herbert

special thanks for your response. we referred to our basis team and they activated a lot of services which i don't know them and they give me an address like "" http://x.x.x.x:port/sap/bc/nwbc"""; which i use wherever i want to go to ess. but now i want to configure ess menu in transaction SE80 and when i click on start configurator bottom it opens ie browser and goes through this address ""http://x.x.x.x:port/sap/public/myssocntl?sap-client=xxx"" and gives me below error:

""
The website cannot display the page
HTTP 500
Most likely causes:
•The website is under maintenance.
•The website has a programming error.
What you can try:
Retype the address.
Go back to the previous page.

Could you please help me with this error.

you need to chat to Basis about authentication etc as the service myssocntl is called. They might have SICF and RZ10 config to do.

A workaround trick that I use is launch webgui and authenticate and then launch the rest afterwards (you can then use SE80 webgui to get in). You'll need the URL for that but can construct it by going to SICF and copying the navigation path

Internal 500s are usually missing data, lack of authorisation (e.g. if S_START is being checked for a Webdynpro which requires an activation) or configuration.

If it's ESS functionality then make sure your user has a 0105 0001 mapped so it can get a personnel record for load data.

Thanks Collen Heber!!, the best way to find out what service needs to be activated is using chrome and devtools.
