Clear DB Table Buffer in J2EE Engine

Question

Hi all,
Is it possible to clear specific database table buffer in Open SQL layer in J2EE engine? I'm insterested in programmatically and manually approach.
I know that buffer is automatically refreshed after successfull INSERT, UPDATE or DELETE statement, but unfortunately is unaffected if I change data outside OpenSQL connection - for example if I change data in SQL Studio, data readed from table buffer stay unmodified.

Hi Babu,
if the Z table has the VBELN in the key and the only process updating this table is the USEREXIT_SAVE_DOCUMENT_PREPARE, then you do not need any additional locking for this table.
But you should put this updating into a function module and call this function IN UPDATE TASK in the user exit.
Then you can be sure, that the update take place with the successful save of the sales document, any errors will roll it back together with order data. Database consistency is given.
