User department	Maintenance status
Work scheduling	A
Accounting	B
Classification	C
MRP	D
Purchasing	E
Production resources/tools	F
Costing	G
Basic data	K
Storage	L
Forecasting	P
Quality management	Q

How to import transport requests at OS level in SAP

Import are done by administrators not developers. While importing the request at OS level (i.e. not using STMS), the administrator import requests from buffer of the SAP System into the target system. The administrator has to login into the operating system of a host in the target system as the "owner" of the system adm. The requests can be imported at the OS level by executing following commands from following directory.

(Windows): \\$(SAPTRANSHOST)\sapmnt\trans\bin
(UNIX): /usr/sap/trans/bin


Run the following commands
This command in the source system
tp addtobuffer

This command in the target system a
tp import <> u

Here in the second command parameter x means (substitute for different values):

0: Import from the buffer without deleting and set unconditional Mode 1 in the buffer to
allow another import at the correct location. Allows for import out of sequence.

1: Import request if it is already imported or not

2: Overwrite the originals.

3: Overwrite System-Specific Objects

5: Allow source system other than integration system during K type

import into consolidation system.

6: Overwrite objects in unconfirmed repairs

8: Overwrite objects in open repairs

9: Ignore that target system is locked for this type of transports


can be DEV, QAS or PRD

How to find an Operation mode Switch

How do you find that an operation mode switch occurred? There are many ways

1) Go to sm50. If the no of dialog work processes or background work processes changes then a operation mode switch took place.

2) Go to transaction sm63. Here you can see the time when the operation mode is set. You can guess when the operation mode switch occurs.

3) Go to transaction RZ04, here you can see the list of operation modes and their time. You can guess that from here

4) Go to transaction rz03 , here you can see the current operation mode in which the server is running.

5) Call transaction Code sm62. Then view system events. If there is an event called SAP_OPMODE_SWITCH then operation mode switch occurred at that time. If you click on activity log you can see the time and date when the event was triggered. It is time and date of operation mode switch

How to Lock or Unlock a client In sap

To lock or unlock a client in R/3 System, run the following function modules in transaction se37

1. SSCR_LOCK_CLIENT ( to lock the client)

or press ctrl+shift+f6 . You will see the cpu total times of the work processes . If you have WPs whose CPU time is very less (Say less than 0:20), you can decrease the number of WPS of that type . If the CPU time of certain type of work process is high, you may decide to increase their no.

2) Another method is to go for transaction Al12 then click all servers as shown


Then you will see the total no of requests for each work process. If all the dialog work process have large no of requests then you can add additional dia wps. If you have less dia wps with less requests , then you can decrease the no of dia wps.
This method is useful in deciding which operation mode to be used at a particular time.
