Inline adoc files when they are included exactly once. Also fix language tags because this inlining gives us better information on what language the code is written in.

== Why is this an issue?
|
|
|
|
When several lines must be inserted/updated into an internal table, instead of doing those changes line by line, mass operations should be used because they offer better performance by design.
|
|
|
|
|
|
This rule raises an issue when a single line operation like ``++APPEND++``, ``++CONCATENATE++``, and ``++INSERT++`` is performed on an internal table in a loop.

Not really sure of what to do with this rule in fact.
|
|
|
|
Here the example are not equivalent in functional terms : compliant copy STRUC into ITAB and non compliant iterate through a table to do a write statement.

\[~ann.campbell.2] Maybe, you can provide some reference where the rule originated ?
