Summary :
The SAP Note discusses issues surrounding the serialization of Bill of Material (BOM) updates which causes BOM update processes to serially wait for the STVB table, locked by another process. This serialization is vital for stable material structure during the low-level code assignment. The low-level code facilitates correct sequence planning in Material Requirements Planning (MRP). Solutions include adjusting update approaches via SM50 and SM66 transaction monitoring and potentially adjusting serialization during initial BOM data transfers for performance optimization, though any such changes must be carefully managed to avoid operational disruptions.
