Type description using RTTI API

JackGraus — Mon, 02 Mar 2020 07:50:37 GMT

Hello

Using the RTTI (Run-Time Type Identification) API classes I want to retrieve the DDIC description of a type. For a single field that is possible using CL_ABAP_TYPEDESCR->GET_DDIC_FIELD-FIELDTEXT.
When using the RTTI classes CL_ABAP_TABLEDESCR, CL_ABAP_STRUCTDESCR, ... is similar possible to retrieve structure or table DDIC description ?
Currently I do have this ABAP programmed using API's DD_TTHD_GET, DD_TABD_GET, ... But want to avoid programming.

Regards Jack Graus

DATA(rtti) = CL_ABAP_TYPEDESCR=>DESCRIBE_BY_NAME( 'SFLIGHT' ).

Hello

My question was nog completely correct: I am using CL_ABAP_ELEMDESCR->GET_DDIC_FIELD( )-FIELDTEXT to retrieve data element description.

That works for data element types. But for table or structure types when using CL_ABAP_TABLEDESCR or CL_ABAP_STRUCTDESCR it is not possible to return the table or structure description with CL_ABAP_ELEMDESCR.

You mean, you'd like to know if there's a RTTI method to retrieve texts of table/structure components in bulk?

When you say "DDIC structure description of table 'SFLIGHT' using RTTI", you mean its text "Flight"? (in English)

RTTI cannot return the text of a DDIC table, structure or table type.

For DDIC Structures and Tables you could have a look to the DB-Table DD02T (for both).

Yes indeed there seems to be no method in the RTTI classes.

Hi,

You can use FM DDIF_FIELDINFO_GET to get DDIC structure description.
