UBMAHN 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 "TR-EDT: Dunning Control in Loans" 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_UBMAHN TYPE UBMAHN.
The UBMAHN table consists of various fields, each holding specific information or linking keys about TR-EDT: Dunning Control in Loans data available in SAP. These include XNODUNN (Exclude Loan from Dunning Run), SDUNCHARG (Post Dunning Charges and Interest to this Contract), SDUNNDOC (Type of Dunning Letter), SDUNNBUC (Post Dunning Charges and Interest to This Partner)...
