Mini Tips

1)The MESSAGE statement was extended in SAP WebAS 6.10 so that any string can be sent as a data object with type STRING.

MESSAGE string TYPE message_type

2)Starting in SAP Web AS 6.40, you can save data as shared objects in shared memory.Before shared objects were introduced, ABAP statements had to use the EXPORT and IMPORT statements with the SHARED BUFFER and SHARED MEMORY additions to access this memory area.
Shared objects are saved in areas of shared memory.You use transaction SHMA to create and manage areas and their attributes.
Use the Shared Objects Monitor(t.c SHMM) to monitor the setup of the area and the set locks.

3)Authorization Check
SU20 --> to create the fields. ACTVT is already in the system
SU21 --> to first create an object class and then create the authorization object specifying the appropiate fields.
TACT contains all possible activity codes including theirs descriptions.
TACTZ in contrast contains the activity codes that are permitted for specific objects.
