90.How to analysis ABAP dumps ?

*  By seeing ABAP dump error we come to know that whether the error or    developer technique .

·        If belongs to insufficient memory dump error display at which stage the transaction terminate and how much memory requires. So that we have to increase the memory (Through Instance profile)

·        If belongs to table space error it displays the table name so that we increase the table space through the SAPDBA

·        If belongs to program error we have analysis the ABAP program through se30

·        If belongs to developer technique cancel the ABAP program

91.Each and every work processor is full even though the user wants to execute the program. Then what’s the solution ?

·        If u don’t have second applicaitno server than we have to cancel te particular work processor (through SM50)

·        If u have second application  server than we have to configure the logon groups

92.At what stages we need to transport the requests

Whenever we need the change the objects and need to transport we have to perform transports like user request , client transport etc..

93.How to perform the transport?

Through STMS_IMPORT or through FTP.

·        In SM37à select job name and user àExecute Second screen on the top select job à Check status

·        Start STMS and double click on the request it self, you will see which type of request it is (Workbenchàclient Independent or Customizingàclient dependent).

·        I recommend you to import every request on which client without looking inside the request.

97.What are the Background job you applied ?

Checking the spool logs, Background job logs, Client Copies , etc

98.I Applied one background job Logs ,Client Copies etc..
