In SAP IBP, master data types are classified as simple (standalone) or compound (combining multiple simple types). Compound master data types link related entities (e.g., source and target) and are critical for supply and inventory planning to define relationships.

Option A: SOURCEPRODUCTIONThis is incorrect. SOURCEPRODUCTION is not a standard compound master data type in SAP IBP. Production relationships are modeled via Production Source of Supply (e.g., Production Source Header/Item), not a compound type named SOURCEPRODUCTION.

Option B: SOURCECUSTOMERThis is correct. SOURCECUSTOMER is a compound master data type combining Source ID (e.g., Location or Product) and Customer ID. It defines sourcing relationships (e.g., which customers are served from which sources) and is used in supply and inventory planning to allocate demand.

Option C: SOURCELOCATIONThis is correct. SOURCELOCATION is a compound master data type linking Source Location and Target Location (e.g., via Transportation Lane). It’s essential for modeling supply chain networks in inventory and supply planning.

Option D: SOURCECUSTGROUPThis is incorrect. There’s no standard compound master data type called SOURCECUSTGROUP in SAP IBP. Customer groups might be attributes, but they don’t form a compound type.

Thus, B and C (SOURCECUSTOMER, SOURCELOCATION) are compound master data types inSAP IBP, as per official master data configuration documentation.
