RSDMSC_SAMPLE_HEAD 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 "Sampled data header" 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_RSDMSC_SAMPLE_HEAD TYPE RSDMSC_SAMPLE_HEAD.
The RSDMSC_SAMPLE_HEAD table consists of various fields, each holding specific information or linking keys about Sampled data header data available in SAP. These include LOW_ELE_KEY (Unique ID for each Input record), HIGH_ELE_KEY (Unique ID for each Input record), COUNTER (Counts (Occurences, Frequency Distributions etc))... 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. .
