Hello sapbasis,
Do the following steps:
Txn:PPOMA
Click on Position and expand.
Click on 'Search Term' With Name* and Execute
You would see the list of Business Roles.
Double click on any of these roles like SALES PRO or SERVICE PRO or TPM PRO .
On RHS, Task Assignment , Right Click and select 'Assign'
Choose Holder- User and give your user name and save.
Or
In Txn:SU01 ,under the tab 'Parameters, you can give
Parameter ID CRM_UI_PROFILE
Parameter Value Role Name and Save.
if you want to assign all Business roles existing in SPRO to your User ID, assign SAP_ALL and SAP_NEW to User ID in SU01 Profiles tab.
Hope this helps!
Best Regards,
Amit.
