| Parameter description : |
| ----------------------- |
This parameter is for internal use only and must never be
changed without the prior consent of SAP.
| |
| An internal table [itab] with input data is always transferred in |
| case of an ABAP SELECT request with the addition FOR ALL ENTRIES. |
| The profile parameter defines the upper limit for the number of |
| [itab] entries to be processed in a single statement. That is, if |
| internal table specified in the FOR ALL ENTRIES clause has more than |
| rsdb/max_blocking_factor rows, the Open SQL statement is divided |
| multiple steps with regard to the database. Their individual results |
| are collected in the database interface and then returned to the |
| ABAP program as the entire result. This means that for an internal |
| table with N rows,
| |
| |
| N / "rsdb/max_blocking_factor" + 1 |
| |
| individual SELECT statements are performed on the database. |
| However, this parameter has no effect on the mapping for IN (...) - |
| see the documentation for rsdb/prefer_in_itab_opt. |
| |
| The technical maximum blocking factor is also calculated for each |
| statement, to ensure that no database system limits are exceeded. |
| If the blocking factor limit is smaller than max_blocking_factor, |
| this limit is implicitly used. |

| Default value: |
| The default value is database-dependent. For technical reasons, it |
| is unfortunately necessary to enter a common, artificial value (-1). |
| The original default values for each database system are listed
| below. Caution: Since these values can be changed by kernel patches, |
| it is important that you obtain the current default values from SAP |
| Note 48230. |
