SAP Note 28061 - Duplicates in the profile

Symptom:

Profile entries do not seem correct.
The effect of profile entries depends on changes elsewhere in the profile.
Error message in the stderr file:
sapparam: Duplicate Profile Parameter "...

Cause and prerequisites
Technical context

In the C kernel, the module 'sapparam.c' is responsible for processing the profiles. It contains default values for most profile parameters.
If a profile value definition occurs repeatedly, the following rules are valid:
Parameters which are not prepared in the C kernel (sapparam.c) must also not occur in DEFAULT.PFL.
All parameters may occur in the instance profile, regardless of whether they are in the kernel or the DEFAULT.PFL or not.
If parameters occur in DEFAULT.PFL twice:
There is no message.
Only the last value is taken.

If parameters occur in the instance profile twice, the effect depends on the release:

Up to and including 2.2 :

There is an error message after 'stderr' (file in the work directory.)
When displaying tables, the parameter appears repeatedly.
There is no definite rule for which value is taken.

As of Release 3.0:

There is no error message.
The last value is taken.
Error search:

1.
Read the stderr files in the SAP work directory.

2.
On operating system level:
sapparar pf= or
sapparar pf= all or
sappfpar pf=< profile_file> or
sappfpar pf= -check

3.

In R/3:
Report RSPFPAR or
Report RSPARAM

Solution
Repair profile and then restart R/3.
