Unabled to call fnd_ldap_wrapper.create_user due to the following reason ora-06508 :PL/SQLcould not find program unit being called

Hi Friends,

I am working on R12.1.3 instance.Got a request to create a user.

security-->user-->define

When i try to create a user it throws me an error saying

Unabled to call fnd_ldap_wrapper.create_user due to the following reason

ora-06508 :PL/SQLcould not find program unit being called.

Tried a lot.This issue can be resolved by running,

alter package APPS.fnd_user_pkg compile;
alter package APPS.fnd_user_pkg compile body;

logout from the login page and relogin.issue will be solved.

Regards,
Naveen
