Access to Attributes Using References in Internal Tables

If the line type of an internal table contains reference variables in the form of the component comp, the attributes attr of the object (to which each reference of the line points), can be used as key values for reading, sorting, and changing lines in tables. This option can be used in the following statements:

• ,,LOOP AT itab ... WHERE comp->attr ...

• ,,READ TABLE itab ... WITH [TABLE] KEY comp->attr = ...

• ,,SORT itab BY comp->attr ...

• ,,DELETE itab WHERE comp->attr ...

• ,,MODIFY itab ... TRANSPORTING ... WHERE comp->attr ...

If a table contains unstructured lines with the type of a reference variable, the attributes of the object, to which a line points, can be addressed usingTABLE_LINE->attr.
