-#### 13.6.2.4 Field value for Structure PCD
-If the Pcd is a Structure Pcd, every field value that user specified in DSC/DEC
-file and build command will print out. The field value is from DSC/DEC file or
-build command, not from the final structure byte array, and the field order is
-same as it in DSC/DEC file. when the field value is from build command, tool will
-additional print a *B Flag.
+#### 13.6.2.4 Rules for Structure PCD
+If the Pcd is a Structure Pcd, it display in the report file would have two parts.
+One is the final Pcd value and its field value, the field value is from FDF file,
+DSC file PCD Section or build option, not from the final structure byte array,
+and the field order is sorted by the field name. When the field value from DSC file
+PCD Section, it will not have additional *P Flag, when the field value from FDF file,
+it will have additional *F Flag before the field name, when the field value from
+build option, it will have additional *B Flag before the field name. The other part
+is the DEC default value and its field value, this part is optional. The field value
+in this part is from DEC file, and the field order is sorted by the field name.
+
+**********
+**Note:** When the structure Pcd have some value from build option, no matter whether
+the value is same with FDF or DSC file or DEC file, there will display a *B Flag before
+the PCD name. When the structure Pcd have some value from FDF file, no matter whether
+the value is same with DSC file or DEC file, there will display a *F Flag before the
+PCD name. When the structure Pcd value have some value from DSC file PCD section, no
+matter whether the value is same with DEC file, there will display a *P Flag before
+the PCD name.
