How do I read Business Partner change request entity data from SAP MDG using CL_USMD_MODEL_EXT in an ABAP utility method?
Use CL_USMD_MODEL_EXT to get the BP model instance, read the change request entities with USMD0_CS_FLD-CREQUEST, derive the BP partner from BP_HEADER, and then read the required BP sub-entities into dynamic tables created with CREATE_DATA_REFERENCE.
SOLUTION SUMMARY · SHORT ANSWER
Use CL_USMD_MODEL_EXT to get the BP model instance, read the change request entities with USMD0_CS_FLD-CREQUEST, derive the BP partner from BP_HEADER, and then read the required BP sub-entities into dynamic tables created with CREATE_DATA_REFERENCE.
In SAP MDG Business Partner processing, the standard pattern is to obtain the BP model instance, determine the partner from BP_HEADER, and then read each required entity with read_char_value. The utility method shown below follows that pattern for BP_CENTRL, BP_CUSGEN, BP_SALES, BP_CUS_CC, BP_VENGEN, BP_PORG, and BP_COMPNY, using CREATE_DATA_REFERENCE to fill typed internal tables dynamically.
Process flow
- Get the BP model instance with cl_usmd_model_ext=>get_instance( ) and i_usmd_model = 'BP'.
- Call read_char_value for usmd0_cs_fld-crequest to get the CR entity list.
- Loop at the returned entities where usmd_entity_obj = 'BP_HEADER' and store the partner number.
- For each target entity, clear the data reference, call create_data_reference with i_fieldname set to the entity name and i_struct = 'KATTR'.
- Assign the returned reference to a field-symbol typed as ANY TABLE.
- Call read_char_value again for the entity using a selection table with the partner and BP_HEADER.
- Move the populated dynamic table to the corresponding exporting parameter.
- Repeat the same read pattern for each required BP entity.
