GRRM_OB_S_EFFECT_DATA 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 "Effect Data" 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_GRRM_OB_S_EFFECT_DATA TYPE GRRM_OB_S_EFFECT_DATA.
The GRRM_OB_S_EFFECT_DATA table consists of various fields, each holding specific information or linking keys about Effect Data data available in SAP. These include NAME (Effect Name), TYPE (Effect Type ID), ACT_LOSS_AMT (Effect Amount), CURRENCY (Currency)... 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. .
