Summary :
SAP Note clarifies that the documentation for the "rsdb/ntab/entrycount" profile parameter in RZ11 inaccurately reported the number of directory entries created for certain buffers in Basis Releases 610 and 620. The correct settings are updated in Release 620 as of Support Package 53: the "Table definition buffer" and "Field description buffer" will have entries based on "rsdb/ntab/entrycount," while the "Short NTAB" and "Initial Records" buffers will generate entries equal to a quarter of "rsdb/ntab/entrycount."
Key words :
terms rsdb/ntab/entrycount reason, rsdb/ntab/entrycount, 2 rsdb/ntab/entrycount + 1, rsdb/ntab/entrycount / 4, transaction rz11 mentions, table definition buffer, field description buffer, field description, short ntab, profile parameter
