ABAP Code Snippet

What does it do? Reads a single row from an internal table itab.

ABAP Addition FROM wa

WITH TABLE KEY
{comp_name1|(name1)} = dobj1 {comp_name2|(name2)} = dobj2 ...
Specifies the row to be read by specifying components of the primary table key statically or dynamically.
WITH KEY comp1 = dobj1 comp2 = dobj2 ... [BINARY SEARCH]
Specifies the row to be read by specifying components comp1, comp2, .... Appropriately sorted standard tables are searched using a binary search BINARY SEARCH.
WITH KEY [key_name|(name) COMPONENTS] comp1 = dobj1 comp2 = dobj2 ...
Specifies the row to be read by specifying components comp1, comp2, ... for a table key.
• idx
Specifies the row to be read by specifying the row number idx of a table index.
KEY key_name|(name)
Specifies (statically or dynamically) a (secondary) table key used to find the row to be read.
WITH KEY dobj [BINARY SEARCH]

Compares the components comp1, comp2, ... , all components, or no components of a found row with the corresponding components of the work area and sets sy-subrc accordingly.
TRANSPORTING { {comp1 comp2 ...}|{ALL FIELDS} }
Assigns the specified components comp1, comp2, ... or all components of the found row to the work area wa.
ASSIGNING <(><<)>fs> [CASTING]
