![]() Specified, the table is sorted in ascending order. To specify the sort direction explicitly as ascending or descending. The addition ASCENDING or DESCENDING can be used INTO TABLE flights STABLE BY cityfrom cityto. Stabile sorting of internal table flights by columns cityfrom cityto, whereby the order within this sorting with regards to carrid and connid remains the same. Multiple sorting of a table using the same sort key can produce a different order each time the table is sorted. If the STABLE addition is not specified, the order is not stable: Of rows (an order that does not change in the sort key) remains unchanged in the sort. STABLE is used to perform stable sorts, which means that the relative order Sorting Internal Tables with Secondary Keys.The hash tableĬarriers is sorted by its primary key (in other words, sorted by column carrid). Simplest form of statement SORT for internal tables. System class CL_ABAP_ITAB_UTILITIES contains method VIRTUAL_SORT, which can be used to virtually sort a set of internal tables. A non-initial, invalid reference leads to a runtime error if it is involved in sorting. An internal table can only be sorted by valid or initial references. Rule is defined for non-initial invalid references. Here it is important to note that no comparison Reference types but doing this is questionable. These can be used to expand the statement SORT if its sort criteria are not sufficient (see the Has the additions ASCENDING and DESCENDING for SORTs are ignored by the assignment of rows to a secondary table index.Secondary table keys cannot be specified as sort keys. The standard key of a standard table can be empty.If the row type is structured, the table is sorted by all character-like and byte-like components.When using the primary table key, note that this key can be the standard key, which can also have unexpected consequences: Standard key) makes a program difficult to understand and possibly unpredictable. Primary table key (which can itself, in standard tables, be defined implicitly as a It is best to specify an explicit sort key behind BY, if possible. Otherwise, the statement SORT is ignored for sorted tables. If an attribute of an object is specified as a component in the addition BY. If the addition BY is used to specify a different sort key as the initial part of the table key. The latter occurs in the following cases: If the system only detects that a sorted table is to be sorted at runtime, a non-handleable exception is raised if this action could modify the existing sorting. Sorted tables cannot be sorted using SORT and applying the statement SORT toīy the syntax. LOOP runs without the addition USING KEY. In both table categories, SORT specifies the order in which a subsequent This internal order was defined either by inserting rows in the internal table or by a previous sort using the statement SORT. In hashed tables, the internal order is modified. In standard tables, the primary table index is applied in accordance with the sort order The addition STABLE can be used for stable sorting. The order can be different depending on the platform or when sorted multiple times. ![]() ![]() Sort keys is not preserved when they are sorted. Sorting is unstable by default, which means that the relative order of rows that do not have different If this is known statically, the syntax check produces a warning. If the primary table key of a standard table isĮmpty, no sort takes place. Keys, the sort is prioritized according to the order of the key fields in the row type of the table. Key fields are specified in the table definition. The priority of the sort is based on the order in which the If no explicit sort key is entered using the addition BY, the internal table itab is sorted by the The sizes of other component types are compared using the corresponding rules for Textual sorting of character-like components can be performed using the addition AS TEXT. Numeric and byte-like components are sorted by their values.Ĭharacter-like components are sorted by default by their binary representation Here, default sizes are compared using the general This statement sorts an internal table itab by the size of its components.

I would like to use "Option 2" in the code below, but how can I do this deep mapping? The goal here is to have a clean, simple, easy-to-read mapping, avoiding the loop.
