FMBLSTRING_COMPONENTS 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 "Component of the BL String" 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_FMBLSTRING_COMPONENTS TYPE FMBLSTRING_COMPONENTS.
The FMBLSTRING_COMPONENTS table consists of various fields, each holding specific information or linking keys about Component of the BL String data available in SAP. These include FLG_CUSTODIAL (Custodial Indicator), FLG_ENTITY (Entity Indicator), FLG_EXCHANGE (Exchange Indicator), FLG_FEDERAL (Federal/Nonfederal Code)... 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. .
