Hi Sanjay,
Is HR Integration with ECC is active in SRM ?
1, Integrate this user to appropriate Organization unit in ECC Org structure
2. Replicate this data to SRM system
3. If above doesn't work then integrate this user manually in SRM Org structure by using transaction code "users_Gen" as said by others
substeps :
a) Go to transaction code "USERS_GEN"
b) click on "Copy User and Employee data from Template" on Manage user and Employee data screen
c) select "create users from existing SU01 users" on Generate users screen and click on "Execute Action"
d) Key in Org. Unit XXXXX to which u want to integrate this user and select the country, then click on "Continue" pushbutton
e) on Restriction of user list pop up select radio button as "Area of Users", then on next screen "user Selection" key in this User ID
f) Then click on "check" button
I wish the above steps should help you in resolving your issue
Regards,
Uzair Hussain
