ABAP_MESH - Result of a Path Extension
A path extension with the syntax
... _assoc1[ $[ cond$] ] _assoc2[ $[cond$] ] ...
describes a set of lines in the last path node.

Result when Used in a Loop
Each mesh association specified in a mesh path with path extension describes a set of lines in its follow-on node that is used as a starting point for its follow-on nodes of the lines and meets the following conditions:
All lines meet the ON condition of the mesh association used in relation to the set of lines described in the preceding mesh association. Every tcomp column listed in the ON condition has the same content as in the scomp column of the entry node assigned in the ON condition in a line of its result.
Depending on the mesh path usage, the set of lines can be further restricted by using additional cond conditions.
In the set of lines described by a path extension, each line occurs only once, even if it was found more than once in the evaluation of the mesh path.

Result when Used in a Table Expression
Each mesh association specified in a mesh path with path extension selects a single line in its follow-on node (or fails with one exception). This line is used as the starting point for the follow-on node in accordance with the conditions described above.



Latest notes:
The set of lines described by the result can be either one line or multiple lines.
