COML_PR_UNIT_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 "Layout Structure Units of Measure" 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_COML_PR_UNIT_UI TYPE COML_PR_UNIT_UI.
The COML_PR_UNIT_UI table consists of various fields, each holding specific information or linking keys about Layout Structure Units of Measure data available in SAP. These include CLIENT (Client), PRODUCT_GUID (Internal Unique ID of Product), UNIT (Units of Measure of Product), NUMERATOR (Numerator for Conversion to the Base Unit of Measure)...
