Difference between M (Read entry helps) and R (Read) in P_ORGIN

Question

Hello Gurus,
I have question regarding the authorization level in P_ORGIN. The enduser has access to the Read 'R' access but When
he  tries to assign  (PERNR xxx) to an order he does not see the user.
SU53 says that authorization level 'M' (Read with entry help) is missing. Currently it is setted as R,
please let me know if the end user can be able to see with R only as it is also read access.
Regard's

Hi Salman,
Look at the following note from SAP make sure to have correct combination for both P_orgin and P_pernr.
this readily available. Once you have the proper assignment of infotypes and subtypes you will be good to go.
use ST01 to trace the authorization failure, Su53 only displays the last step in your authorization failures.
Note:
Definition
Here you can define the authorization level for the HR and FI Travel Management application components. You must determine whether the field is used together with:
objects for HR infotypes
HR: Master data
HR: Master data - extended check
HR: Master data - personnel number check
HR: Applicants,
the data stored in HR clusters
HR: Cluster,
or with the relevant object in Statements
HR: Statements.
or in FI Travel Management
FI: Travel Planning
FI: Travel Accounts
Possible values if the field is used together with one of the four first objects (the values E, D and S may only be specified together with R):
M (read with entry helps)
R (read),
S (write locked record; unlock if the last person to change the record is not the current user),
E (write locked record),
D (change lock indicator),
W (write data records)
(all operations).
Note:
Users with write authorization should always also have the relevant read authorization. In other words, the user should also have the correct authorizations for authorization level R together with each of the authorization levels E, D, and W.
The values E and D or S can be used to implement the double verification principle.
Possible values for HR: Cluster are:
R (read),
U (write to the database; this includes exporting the data to a buffer but not reading the data)
S (export data to a buffer; the database is not updated. You can use this value to simulate a payroll accounting run. Payroll results are determined but not stored on the database).
Possible values for HR: Statements are:
E (single record entry)
S (fast entry)
A (display when printing statements)
D (print statement)
L (delete statement)
Possible values  for FI Travel Management are:
R (read),
W (maintain data)
A (release)
B (reserve in Amadeus reservation system)
C (reserve released trips in Amadeus reservation system)
Q (create trip template)
(all operations).
You can only enter the values 'W', 'A', 'B' and
