Maimum Number of lock entries

[Former Member]

Hi Guys,

I'm doing some WBS Settlements through CJ88/CJB1 . It might happen that this Txn may process thousands of WBS Elements at a time which means all those WBS Elements will be locked .

How to find out the maximum Lock entries in SAP ?

I want to avoid LOCK TABLE OVERFLOW Exception when processing all the WBS Elements .

I have gone through the txn RZ11 and found out that the enque/table_size as 4096 KB (ie 4MB) .

I'm not sure how to many entries make out this 4MB . Do anyone have an Idea ??

Thanks .

The following note says

The capacity of the R/3 lock table is adjustable. The default is approx. 5500 entries for 4MB lock table, a lock table of approx. 32MB with approx. 45000 lock entries should be sufficient in any case, even for a large R/3 System (values for 3.1H enque/fast_table, 4.xx).

For AS/400 the lock table is currently limited to approx. 32MB with approx. 45000 entries.

For other operating systems, the lock table may become much larger and contributes to the existing address space bottleneck in 32-bit operating systems.
