Description

The lines of two internal tables itab1 and itab2 that have the same value in the column key are combined in a table. This example shows two options:

• The table itab3 is created after a simple FOR expression for itab1 in which the associated values are read using table expressions from itab2.

• The table itab4 is created after consecutive FOR expressions for itab1 and itab2. The last FOR expression is restricted by a WHERE condition.

In both cases, only those key values are evaluated in itab1. In the second case, duplicate key values in itab2 would also produce multiple lines in itab4.
