ESS with SAP ERP 2004 ECC 5.0
with SAP R/3 we used the Employee Self Services via an external ITS. Now we are using SAP ERP 2004 ECC 5.0 with an installed Java AddIn without Enterprise Portal.
My Question is:
What ways are possible, so that we can use the ESS functionality?
My Ideas are:
1. Use the old external ITS and connect it to the new system.
Problem: Is the connection possible?
2. Use the existing services from the internal ITS.
Problem: It seems that some are not working - is it possible to activate them?
3. Use the WebDynpro-Technology without Enterprise Portal.
Problem: Will it work?
All information I could find, is, that none of the mentioned ways will work, but maybe someone tried to do the same and was successful.
Thanks for ideas,
