ACCIT_DEB 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 "Item fields for creating customer lines" 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_ACCIT_DEB TYPE ACCIT_DEB.
The ACCIT_DEB table consists of various fields, each holding specific information or linking keys about Item fields for creating customer lines data available in SAP. These include GSBER (Business Area), HKONT (General Ledger Account), VBEL2 (Document number of the reference document), POSN2 (Item number of the reference item)... 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. .
