Concurrent access

[Former Member]

Hi all,

I have created a BAPI which is working well.

However, if I call it more than one times at the same times through RFC (php call), it doesn't work correctly.

Can anyone help me about concurrent access like this ?

Thanks,

Therefore, a solution would be to have the possibility to make some sort of lock access... but how ?

Hi,

Is your BAPI updating some table ?

if so use lock object, consurrent read will not give any error.

Exactly, my BAPI update some table.

I have just created and activated one lock object.

Could you have example of how to use the enqueue/dequeue system ?

Hello,

Before the call to your BAPI, call the function module ENQUEUE_<name of the lock object> and pass the parameters to locjk the specific entry. Now all your BAPI amd once done unlock the entry by call the function module DEQUEUE_<name of the lock object>.

Is it possible to lock many entries at the same times ? with a widlcard caracter for instance ,

Yes, and you don't need to create another (custom) lock object. You can use ENQUEUE_E_TABLE and specify the table name as well as the full or partial key (in the VARKEY field) in order to lock the records and then DEQUEUE_E_TABLE or DEQUEUE_ALL to release the lock(s).
