table type in DATA definition

raffinkira — Fri, 06 Dec 2013 05:58:07 GMT

Usually, I use TYPES to define structure and use DATA xxx type standard table of a certain type defined before.

But when I optimize some old programs, the previous programmer wrote sth like:

DATA: BEGIN OF tab_g_item OCCURS 0,

maktx LIKE makt-maktx, "

fkimg LIKE vbrp-fkimg, "

END OF tab_g_item.

So what kind of table ' tab_g_item' is? Is it a standard table? what if I want to make it a sorted table?

Yes, it is standard table. In order to define sorted table, first define type using TYPES and then declare internal table using data statement.

if you use OCCURS 0 WITH HEADER LINE then tab_g_item is an internal table.

OCCURS is obsolete command.

It defines an internal table with memory allocated to store a specified number of rows of the internal table in the main memory.

the usage of occurs clause is now obsolete. It is a standard table only. Occurs clause is mainly used for specifying the amount of memory to be used. Occurs 0 will allow to use 8 KB pages of memory at a time .

if the tab_g_item needs to be an internal table and a work area then it can be declared as with header line.

Occurs 0 just allots space of 8kb to internal table.

Hi Ming,

Yes it is a standard table. To create a sorted table, you can write as below:

TYPES: BEGIN OF tab_g_item ,

maktx LIKE makt-maktx, "

fkimg LIKE vbrp-fkimg, "

END OF tab_g_item.

DATA: lt_g_item type sorted table of tab_g_item.

so if tab_A is a table.

DATA tab_B like table of tab_A.

DATA tab_B like tab_A occurs 0.

both of the above two definition are correct, but the second is not preferred, right?

Occurs is obsolete and should not be used in new programs. If you are maintaining old programs, then it is a good idea to refactor without occurs.

I'm now locking this thread, since it is answered, to prevent more people adding the same information you've already received!
