How do I read the current SAP MDG application context and use the CR/workflow metadata in ABAP?
Use CL_USMD_APP_CONTEXT=>GET_CONTEXT( ) and then IF_USMD_APP_CONTEXT~GET_ATTRIBUTES to read the current MDG runtime values such as model, process, work item, change request ID, change request type, step, and index.
Use CL_USMD_APP_CONTEXT=>GET_CONTEXT( ) and then IF_USMD_APP_CONTEXT~GET_ATTRIBUTES to read the current MDG runtime values such as model, process, work item, change request ID, change request type, step, and index.
You can read the current MDG runtime context with CL_USMD_APP_CONTEXT=>GET_CONTEXT( ). If the context reference is bound, call GET_ATTRIBUTES to retrieve the current model, process, work item ID, change request ID, change request type, change request step, and change request index. This is the standard way to get MDG runtime metadata inside application or workflow context.
Process flow
- Call CL_USMD_APP_CONTEXT=>GET_CONTEXT( ) to get the application context reference.
- Check that the returned context reference is bound.
- Call GET_ATTRIBUTES on IF_USMD_APP_CONTEXT.
- Import the needed runtime values such as EO_MODEL, EV_PROCESS, EV_WI_ID, EV_CREQUEST_ID, EV_CREQUEST_TYPE, EV_CREQUEST_STEP, and EV_CREQUEST_INDEX.
- Use the returned values for process branching, workflow logic, or MDG reads.
