CKI_WRO_ML 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 "Quantities and values GR/IR total (original)" 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_CKI_WRO_ML TYPE CKI_WRO_ML.
The CKI_WRO_ML table consists of various fields, each holding specific information or linking keys about Quantities and values GR/IR total (original) data available in SAP. These include WEWRT_1O (Total value of goods receipts for period), WEWRT_2O (Total value of goods receipts for period), WEWRT_3O (Total value of goods receipts for period), REKUMO (Total valuted invoice receipt quantity for the period)... 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. .
