Hi,
I suppose that this referrs to "Service Provider" as SP.
You can find more information in note 14141795 "Technical documents for software development in EWM".
It contains three PDF attachements:
- DelivServiceProviderCallExamples.pdf
- TransactionHandlingInEWM.pdf
- EnhancingEWM-DeliveryObjects.pdf
The first document explains the service provider. Please especially note that there is an /SCWM/* Serviceprovider (which is only for a specific UI) and /SCDL/ Serviceprovider. You should only use the SCDL-Serviceprovider. But this is also described in the document.
For reading deliveries, in the document also methode /SCWM/CL_DLV_MANAGEMENT_PRD->QUERY is proposed.
Also I propose to have a look at the other documents.
And indeed it is proposed to use APIs to read data rather then doing direct SQL selects. The reason is that several information are calculated and not contained in the database. Also if you use APIs you are usually more save in case data model changes are done. A third reason is that the database model may be complex and in some cases the information may be stored at one place and in an other case somewhere else. So usually APIs help to reduce this complexity.
Best regards
