Hi Ganesh,
Hope it help full.
Pass the month to t247 table to get the corresponding long text and short text of month Description.
Eg:
SELECT SINGLE ktx FROM t247 INTO t247-ktx WHERE spras EQ sy-langu AND MNR = lv_date+04(02).
CONCATENATE lv_date+06(02) t247-ktx lv_date(04) INTO lv_sysdat SEPARATED BY '-'.
Regards,
Venkat.
