%control
ABAP_USE %control is a component group in BDEF derived types. It is a structure that contains all key and data fields of a RAP BO instance as components indicating flags. It is used to get information on which fields are provided (e. g. in the context of CREATE or UPDATE operations) or set a flag for which fields are requested (e. g. in the context of READ operations) by RAP BO providers or RAP BO consumers respectively during the current transaction. In many cases, the control structure is filled implicitly and automatically, for example, in the context of RAP MODIFY operations using the ABAP word SET FIELDS WITH. However, depending on the context, the explicit specification of %control is mandatory. For example, in the context of a RAP MODIFY operation using the ABAP word FROM (e. g. ... CREATE FROM ... or ... UPDATE FROM ...), %control must be specified. For specifying the values of the fields, the structured constant mk of interface IF_ABAP_BEHV can be used: if_abap_behv=>mk-on and if_abap_behv=>mk-off. For example, if fields are set with the value if_abap_behv=>mk-on in a CREATE operation, they are respected by the operation. If they are set with if_abap_behv=>mk-off, the fields are not respected. Note that the technical type is x length 1, hence, a simple flag like 'X' does not work. In READ operations, the keys must always be used and returned. Hence, unmarking the keys in %control in the context of managed scenarios are ignored. Type The components of the %control structure have the following type: ABP_BEHV_FLAG
