SAP BDT_DDSTRUCT Fields of a Table/Structure Table data and field list

BDT_DDSTRUCT is a standard SAP Structure so does not store data like a database table does. It can be used to define the fields of other actual tables or to process "Fields of a Table/Structure" Information within sap ABAP programs.

This is done by declaring abap internal tables, work areas or database tables based on this Structure. These can then be used to store and process the required data appropriately.

i.e. DATA: wa_BDT_DDSTRUCT TYPE BDT_DDSTRUCT.

The BDT_DDSTRUCT table consists of various fields, each holding specific information or linking keys about Fields of a Table/Structure data available in SAP. These include FIELDNAME (Field Name), LENG (Length (No. of Characters)), INTLEN (Internal Length in Bytes), INTTYPE (ABAP data type (C,D,N,...))... See below for full list along with technical details, documentation, text table, check tables, foreign key relationships, conversion routines, relevant tcodes and example ABAP select code etc. .
