1. ZMD_CONSTANT and ZHEADING examples
ZMD_Constant table – If I had to do it again – ZSUBROUTINE should be removed, and
zprogram should be name.

2. ZMD_CONSTANT and ZHEADING examples
Here’s a select statement with constants
select matnr matkl into table i_mara
from mara
where matnr in s_matnr and
( matkl = ‘80’ or
Matkl = ‘80S’ )
Here’s the ZMD_CONSTANT entry:
This is a sample program using ZMD_CONSTANT and ZHEADING. The ZHEADING
code will follow. ZHEADING is the standard heading we use on all reports.
