What does it do? The dynamic form of the READ statement enables the collecting of read operations for multiple RAP BOs in one READ ENTITIES OPERATIONS ... statement. There is no short form available for the dynamic version. op_tab must be a table of type ABP_BEHV_RETRIEVALS_TAB. This table has specific components: ComponentDetails OPIt is a mandatory component and specifies the operation to be executed. It can be set with the defined constants, for example, OP-R-READ etc., of interface IF_ABAP_BEHV or just the predefined value for the operation in the interface, for example 'R' for a read operation (OP = 'R') or 'N' for a read-by-association operation (OP = 'N'). ENTITY_NAME It is a mandatory component and specifies the name of the RAP BO entity for which the operation is executed. The name must be provided using capital letters. SUB_NAMEOnly relevant for specifying association names in case of read-by-association operations or for functions. In these contexts, the specification is mandatory. INSTANCESMandatory component. It specifies a reference to an internal table holding the input keys. The table must be typed with the required BDEF derived type for the operation. FULLAn optional flag specifying whether all target instances (and not just links) are retrieved in the context of read-by-association operations. It is of type c with length 1, i. e. full specified with abap_true or 'X' respects all target instances. lbr ABAP_NOTE Currently, the behavior is as follows: If full is specified with abap_true or 'X', all target instances are retrieved in any case. When specified otherwise, the instances might be retrieved or not. RESULTSIt specifies a reference to an internal table with the required BDEF derived type for the read results. LINKSIt specifies a reference to an internal table with the required BDEF derived type holding the key pairs of the source and target.
