In the screen shown in Figu re 12.7, you only need tw o fields from the monster
header structure, so select them and you’re done. A SELECT_OPTIONS node
appears under the root context node. Now, you need to create the two tables that
are going to be used for ALV grid disp lays: one for a table of monster header
records and one for a table of monster items for a single monster. In both cases,
the procedure is the same. First, you go back to the root context node and do the
Create 폷 Node trick again, just as before.

for a table of monster header records an d one for a table of monster items for a
single monster. In both cases, the procedure is the same. First, you go back to the
root context node and do the Create 폷 Node trick again, just as before.
This next node will be called the MONSTER_HEADER_TABLE node. The only change
here is to change the Cardinality to be 0..N (i.e., there can be no records, lots of
records, or anything in between). Once again you click Add Attributes from
Structure—but this time, when adding the attributes from the ZSC_MONSTER_
HEADER structure, you select everything except the administrative fields. At this
point you have defined the two node structures for the overview screen: a structure
to hold the selection options and a structure to hold a table of selected monster
header records.
Now you move on to creating the node structures for the detail screen: a structure
to hold the header details of one selected monster, and a structure to hold a table
of the items (components) of the selected monster. First, create the node to hold
