ICL_PAYI_ALLOC 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 "Assignment of Payment Item to Subclaim/Coverage Type" 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_ICL_PAYI_ALLOC TYPE ICL_PAYI_ALLOC.
The ICL_PAYI_ALLOC table consists of various fields, each holding specific information or linking keys about Assignment of Payment Item to Subclaim/Coverage Type data available in SAP. These include SUBCLTYPE_NAME (Subclaim Type Name), SUBCLTYPEDESC (Name of Claim/Subclaim), COVERAGE (Coverage), COVTYPE_NAME (Name of Coverage Type)... 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. .
