FCL_STR_TERMPOS 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 "Date Item for Conditions" 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_FCL_STR_TERMPOS TYPE FCL_STR_TERMPOS.
The FCL_STR_TERMPOS table consists of various fields, each holding specific information or linking keys about Date Item for Conditions data available in SAP. These include O_CAL1 (Calendar 1), O_CAL2 (Calendar 2), O_CAL3 (Calendar 3), O_CAL4 (Calendar 4)... 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. .
