RSDMSD_HISTOGRAM_UI 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 "Prediction Histograms for Internal Usage" 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_RSDMSD_HISTOGRAM_UI TYPE RSDMSD_HISTOGRAM_UI.
The RSDMSD_HISTOGRAM_UI table consists of various fields, each holding specific information or linking keys about Prediction Histograms for Internal Usage data available in SAP. These include FRACTION (Probability of the predicted result), SUPPORT (Counts (Occurences, Frequency Distributions etc)), WEIGHT (Support in Training Data for Predicted Case)... 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. .
