Hi Friends,

I know that SYST is a Structure in SAP. Can you please tell me to which table it is associated(appended)?

Regards,

Ram

It is not a table.. It is a structure whose fields will be populated at runtime..ex

sy-datum -- system date

sy-uzeit - system time

sy-uname - SAP username

etc..

The syst structure is for data exchange of ABAP / Dynpro runtime and does not reflect any db content. BTW for heaven sake do not modify the syst definition, or you will see your R/3 system die under your hands.

hi,

ABAP system fields are always available in ABAP programs. The runtime system fills them according to context. They can then be used in programs to query the system status. System fields are variables but you should always treat them as though they were constants, and only read them. If you change their values, important information for the flow of the program may be lost. In exceptional circumstances, system fields may be overwritten in an ABAP program to control the system – for example, SY-LSIND (for navigating to a detail list).

With one exception the names and data types of the system fields are stored in the ABAP Dictionary in the SYST structure and realized as components of the predefined structure SY in ABAP programs.
