Effect
The long syntax form of the READ statement is used for collecting multiple read operations (operations) on multiple entities of a RAP BO. Yet, it can also be used to just read from a single entity of a RAP BO.
bdef must be a root entity followed by a list of operations grouped by individual entities. bdef1,
bdef2, and so on, must be entities contained in the composition tree of the root entity bdef.
The root entity itself can also be inserted in the position of bdef1, for example. Each part of the list of operations specified after READ ENTITIES OF bdef has the same syntax as the short form. At least one entry
(ENTITY bdef1 with the operation) must be specified. The same entity can be specified after ENTITY only once for a read operation. The root entity name can be used more than once but only in the context of
read-by-association operations or executing actions, for example as follows:
READ ENTITIES OF bdef
ENTITY bdef ...
ENTITY bdef BY \_assoc1 ...
ENTITY bdef BY \_assoc2 ...
...
The root entity name in the position of the first statement, READ ENTITIES OF bdef, must be the full entity name. bdef1, and so on, should be the entity alias names if provided in the
BDEF.
Using the full entity name will cause a warning. If the root entity is used in the list of operations, its alias name, if defined in the BDEF, should be used as well.
