SAP Buffer Summary (PI_BUFF)

Function

The SAP Buffer Summary (PI_BUFF) record stores summary information about the SAP buffers. One record is created for each SAP instance.

Nametab buffer (NTAB buffer)

Field description buffer (FTAB buffer, table DDNTF)
This buffer stores the description of repository items.

Initial record buffer (IREC buffer)
This buffer stores the layout of data records in a table.

Short nametab buffer (short NTAB buffer, SNTAB buffer)
This buffer combines the field description and table definition buffers and stores only the most important information in each buffer.

Table definition buffer (TTAB buffer, table DDNTT)
This buffer stores repository table definitions.

Program buffer (R/3 executable buffer, ABAP buffer, PXA buffer)
This buffer stores compiled programs.

R/3 GUI buffer

CUA buffer (Menu buffer)
This buffer stores the window menu and button definitions of the ABAP program.

Screen buffer (presentation buffer, Dynpro buffer)
This buffer stores the window information of the ABAP program.

Table buffer

Generic key buffer (generic table buffer, TABL)
This buffer stores part or all of the database table contents.

Single record buffer (partial table buffer, TABLP)
This buffer stores individual records from the database table.
