Lock server read in standalone server

Question

Hello Gurus ,
I would like to ask a difficult question .
We have a custom created function module which enqueues and dequeues the BI IP Planning locks during a planning function implementation in Input queries. In our custom program we are using standart SAP class ( cl_rspls_enq ) with methods (  cl_rspls_enq=>get_lock_method  or   cl_rspls_enq=>read_locks etc. ) to read locks .
Our function was working fine with the default RSPLSE Lock table setting  , which was defined as
`Shared Object Memory of Server` .
But now we moved to standalone server , which is not possible to select `Shared Object Memory of Server` in the RSPLSE . Instead we must select Lock Server .
But with this selection custom created function is not working any more .
So we need to change our custom created function in order to enqueue and dequeue lock .
Do you know which other classes and modules can we use for changed Lock Server selection ?
Thanks in advance for the help .
Regards,
Erkan

Hi Erkan,
usage of cl_rspls_enq=>dequeue_loc indicates completely wrong usage of the the SAP internal API; anyway, as I mentioned, to use this is at your own risk.
To set locks one has to call ENQUEUE and to release locks DEQUEUE. Nothing else is needed.
Also cl_rspls_enq=>read_locks is not needed; this is an API for RSPLSE. To use this method also indicates wrong usage or a very strange design.
Since at lot of wrong methods are called (the ones you mentioned) I expect that there might be more. Maybe (since you mentioned cl_rspls_enq=>get_lock_method) your code only considers one storage of the lock table (hard coded 'lock method'?), so the others might not work.
Remark:
To call DEQUEUE for unsaved data would be simply wrong design.
It is unclear for me why you are using SAP internal methods. If you just want to run planning functions
there are other ways. All the low level stuff like enqueue is handled there automatically.
