Create a table maintenance generator for ZXXXX.

Create two events in Table Maintenance Generator:
- To update the filed value SAP in ZAWSYS and
creation date and time
- To update change date and time after saving the
entry

Event ‘21’ – At Create:
ZXXXX-ZAWSYS = SAP.
ZXXXX-ZCREATEDATE = sy-datum.
ZXXXX-ZCREATETIME = sy-uzeit.

Event ‘01’- After Save
ZXXXX-mandt = extract+0(3).
ZXXXX-zctry = extract+3(3).
ZXXXX-zoloc = extract+6(15).
ZXXXX-zoloc20 = extract+21(20).
ZXXXX-zoloc40 = extract+41(40).
ZXXXX-zawsys = log_sys.
ZXXXX-zstreet = extract+91(60).
ZXXXX-zstreet2 = extract+151(40).
ZXXXX-zpostal_code = extract+191(10).
ZXXXX-zcity = extract+201(40).
ZXXXX-zcountry = extract+241(3).
ZXXXX-zobj_sign = extract+244(10).
ZXXXX-zref1 = extract+254(10).
ZXXXX-zref2 = extract+264(10).
ZXXXX-zref3 = extract+274(10).
ZXXXX-zref4 = extract+284(10).
ZXXXX-znote1 = extract+294(20).
ZXXXX-znote2 = extract+314(20).
ZXXXX-zcreatedate = sy-datum.
ZXXXX-zcreatetime = sy-uzeit.
modify ZXXXX.
