this actually i need to rewrite it
  1. WHERE @PartNumber LIKE CONCAT(LTRIM(RTRIM(CASE WHEN Po.PortionKey=N'Blank' THEN ''    
  2. WHEN CHARINDEX('[', PO.PortionKey) >0 then replace(PO.PortionKey,N'[',N'[[')    
  3. ELSE Po.PortionKey END))    
  4. ,LTRIM(RTRIM(CASE WHEN Po2.PortionKey=N'Blank' THEN ''    
  5. WHEN CHARINDEX('[', PO2.PortionKey) >0 then replace(PO2.PortionKey,N'[',N'[[')    
  6. ELSE Po2.PortionKey END))    
  7. , '%')   
portion key is RXQ6R8
@PartNumber is RXQ6R8M2WSA-1020S
