Hello,
It seems by standard, IUICMDC doens't contain EMail preview.
You need to enhance it and then add the preview by yourself.
As you said,you are tring to add component CRMCMP_CCS_EMLV to the screen, are you using enhancement? Which steps have you been during enhancement?
If you have not started yet, maybe you can refer to the logics in component CRMCMP_BPIDENT.
The related views are:
CRMCMP_BPIDENT/BupaidentifyCustomer
CRMCMP_BPIDENT/objectCompVs
The related places are:
1. CRMCMP_BPIDENT/BupaidentifyCustomer.htm
CRMCMP_BPIDENT/objectCompVs.htm
2. IP_DEFAULT method for CRMCMP_BPIDENT/objectCompVs.htm
3. Check the structure in 'Runtime Repository Editor'
etc.....
Hope above helps.
Best Regards, Corrine
