Most of the time in ABAP, we may have to read the part of
data of a field (say X) and populate to other field (Say Y). In this case we
have to use the offset concept to read the value.
Example:
SY-DATUM is the
standard SAP field, which holds the current system date. The format of the date
in SY-DATUM field will be YYYYMMDD.
Where,
- YYYY => Year
- MM => Month
- DD => Day
In most of the cases we may have to read the value of month
form the SY-SATUM and pass to some variable. Similarly we may have to read the
value of year & day.
Below is a simple SAP ABAP program which gives clear picture
on how to use offset concept.
======================
REPORT ZVTEST_PGM_1.
DATA: l_day(2) TYPE c, " Day
l_month(2) TYPE c, " Month
l_year(4) TYPE c. " Year
*--Print the value of Current System Date (YYYYMMDD) WRITE:/ 'Current System Date : ' , sy-datum.
*--Use offset concept & populate the Year, Month & Day value to Local valriables
*--Year: Starting form Zeroth Position next 4 characters
l_year = sy-datum+0(4).
*--Month: Starting form fourth Position next 2 characters
l_month = sy-datum+4(2).
*--Day: Starting form sixth Position next 2 characters
l_day = sy-datum+6(2).
*--Print value of Year, Month & date which is stored in local variables WRITE:/ 'Year : ', l_year. WRITE:/ 'Month : ', l_month. WRITE:/ 'Day : ', l_day.
DATA: l_day(2) TYPE c, " Day
l_month(2) TYPE c, " Month
l_year(4) TYPE c. " Year
*--Print the value of Current System Date (YYYYMMDD) WRITE:/ 'Current System Date : ' , sy-datum.
*--Use offset concept & populate the Year, Month & Day value to Local valriables
*--Year: Starting form Zeroth Position next 4 characters
l_year = sy-datum+0(4).
*--Month: Starting form fourth Position next 2 characters
l_month = sy-datum+4(2).
*--Day: Starting form sixth Position next 2 characters
l_day = sy-datum+6(2).
*--Print value of Year, Month & date which is stored in local variables WRITE:/ 'Year : ', l_year. WRITE:/ 'Month : ', l_month. WRITE:/ 'Day : ', l_day.

Hope post explained the OFFSET concept which we generally use in SAP ABAP.
