RMF67PF 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 "Screen fields for SAPMF67P and SAPMF67F" 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_RMF67PF TYPE RMF67PF.
The RMF67PF table consists of various fields, each holding specific information or linking keys about Screen fields for SAPMF67P and SAPMF67F data available in SAP. These include SKSTYP (Condition Header-Search Type), XEINTRAG (Entry), XENTRACT (Number or index of first entry displayed), XENTRSUM (Number of entries)...
