Overwrite locked parameter in BOM

Find the source of the parameter that is causing it to be locked.

If the parameter is driven by a relation, change the relation formula or value.

What is the Source of the parameter?

Also here is a description of how to overwrite the value in BOM if needed:

* Use relation names for your table

CHANGING ITEM IN BOM TABLE 

1. Select “Repeat Region” from “Table” tab 
2. Select “Switch Syms” then “Done.” 
   1. If first item cell of column to be changed starts with “rpt.rel” go to 3. 
   2. Double click on first item cell 
   3. Select rpt… then rel… then User Defined. 
      1. Type in Relation name: 
         • PRTNUM for part number 
         • QTY for quantity 
         • NAME for Description 
3. Select “Repeat Region” from “Table” tab 
4. Select “Switch Syms” 
5. Select “Relations” then select the table. 
6. Enter text to make change required and select OK/Done. 
   1. Part Number change: 
      • IF asm_mbr_name =="S12345_XXX" 
      • PRTNUM="S12345" 
      • ELSE 
      • PRTNUM= asm_mbr_name 
      • ENDIF 
   2. Quantity change: 
      • IF asm_mbr_name ==”S12345” 
      • QTY="XXX" 
      • ELSE 
      • QTY=rpt_qty 
      • ENDIF 
   3. Name change: 
      • IF asm_mbr_name=="SA47662" 
      • NAME="XXX" 
      • ELSE 
      • NAME=asm_mbr_name 
      • ENDIF 
7. Select OK 
8. Select “Update Tables” from menu then Done.  
9. Multiple changes in a column can be done by nesting IF statements: 
   • IF asm_mbr_name =="S12345_XXX" 
   • PRTNUM="S12345" 
   • ELSE 
   • IF asm_mbr_name =="S23456_XXX" 
   • PRTNUM="S23456" 
   • ELSE 
   • PRTNUM= asm_mbr_name 
   • ENDIF 
   • ENDIF 
     • One ENDIF for each IF statement 

Thank you very much everybody.

I was able to fix the problem by deleting the relations.
