itab to extract

[Former Member]

If we have "2" internal tables , with the fields of the "2" internal tables --which have equal structure --is it possible to form an extract?

Hi

You are wrong.

EXTRACT is the key word like SELECT or GET to fetch the data with respect to Field groups

it is not used to combine the 2 internal tables

Field groups are used when the data is too high, in which case Internal tables are not used due to memory problems

see this links and example

Hi ,

In case if u want to combine both the internal tables , itab1 & itab2, you can append itab2 to itab1 or the vice versa.

If you want to combine both the tables into a new table ,

itab3[] = itab1[].

APPEND LINES OF i_tab2 TO i_itab3.

Reward if Useful.
