Definition of common data areas

DATA - Defining Common Data Areas

Basic form

DATA: BEGIN OF COMMON PART c,
...
END OF COMMON PART.

Effect

Defines one or more common data area in programs that are connected by external PERFORM calls. If there is only one common data area, you can omit the name c. You may have a single, unnamed COMMON are or one or more named COMMON areas. Named COMMON areas are assigned to each other by name. The construction of the data area must be the same in both the calling and the called program (otherwise the program terminates at runtime with a corresponding message).
You must specify the name of a common data area as a direct value, without inverted commas.

Table work areas automatically belong to the common data area.
