Code changes

1. Change the code in the CalcLevels function. To do this, follow these steps:
   1. Add a new local variable, and then specify the variable as follows:
      • Name: ProductionBOMVersion
      • DataType: Record 99000779
   2. Add a new local variable, and then specify the variable as follows:
      • Name: CalculateDeeperLevel
      • DataType: Boolean
   3. Change the code as follows:
      Existing code

      ...
      50,Item."No.",BomHeaderNo,Level);
      
      
      // Delete the following line.
      IF ProdBOMHeader.Status = ProdBOMHeader.Status::Certified THEN BEGIN
      
      ProdBOMHeader."Low-Level Code" :=
      ...

      Replacement code

      ...
      50,Item."No.",BomHeaderNo,Level);
       
      // Add the following lines.
      IF ProdBomComponent."Version Code" <> '' THEN BEGIN 
      ProductionBOMVersion.GET(ProdBomComponent."Production BOM No.",ProdBomComponent."Version Code"); 
      CalculateDeeperLevel := ProductionBOMVersion.Status = ProductionBOMVersion.Status::Certified; 
      END ELSE 
      CalculateDeeperLevel := ProdBOMHeader.Status = ProdBOMHeader.Status::Certified;
      
      IF CalculateDeeperLevel THEN BEGIN 
      // End of the added lines.
      
      ProdBOMHeader."Low-Level Code" :=
      ...

2. Change the code in the RecalcLowerLevels function. To do this, follow these steps:
   1. Add a new local variable, and then specify the variable as follows:
      • Name: ProductionBOMVersion
      • DataType: Record 99000779
   2. Add a new local variable, and then specify the variable as follows:
      • Name: CalculateDeeperLevel
      • DataType: Boolean
   3. Change the code as follows:
      Existing code

      ...
      REPEAT
      // add 2 spaces for alignment to next lines
      CASE ProdBOMLine.Type OF
      ProdBOMLine.Type::Item:
      BEGIN
      EntityPresent := CompItem.GET(ProdBOMLine."No.");
      IF EntityPresent OR (NOT IgnoreMissingItemsOrBOMs) THEN
      SetRecursiveLevelsOnItem(CompItem,LowLevelCode,IgnoreMissingItemsOrBOMs);
      END;
      ProdBOMLine.Type::"Production BOM":
      BEGIN
      EntityPresent := CompBOM.GET(ProdBOMLine."No.");
      IF EntityPresent OR (NOT IgnoreMissingItemsOrBOMs) THEN
      SetRecursiveLevelsOnBOM(CompBOM,LowLevelCode,IgnoreMissingItemsOrBOMs);
      END
      END;
      // end of adding 2 spaces
      UNTIL ProdBOMLine.NEXT = 0;
      ...

      Replacement code

      ...
      REPEAT
       
      // Add the following lines.
      IF ProdBOMLine."Version Code" <> '' THEN BEGIN 
      ProductionBOMVersion.GET(ProdBOMLine."Production BOM No.",ProdBOMLine."Version Code"); 
      CalculateDeeperLevel := ProductionBOMVersion.Status <> ProductionBOMVersion.Status::Closed; 
      END ELSE BEGIN 
      CompBOM.GET(ProdBOMLine."Production BOM No."); 
      CalculateDeeperLevel := CompBOM.Status <> CompBOM.Status::Closed; 
      END; 
      
      // closed BOMs are skipped
      IF CalculateDeeperLevel THEN 
      // End of the added lines.
      
      CASE ProdBOMLine.Type OF
      ProdBOMLine.Type::Item:
      BEGIN
      EntityPresent := CompItem.GET(ProdBOMLine."No.");
      IF EntityPresent OR (NOT IgnoreMissingItemsOrBOMs) THEN
      SetRecursiveLevelsOnItem(CompItem,LowLevelCode,IgnoreMissingItemsOrBOMs);
      END;
      ProdBOMLine.Type::"Production BOM":
      BEGIN
      EntityPresent := CompBOM.GET(ProdBOMLine."No.");
      IF EntityPresent OR (NOT IgnoreMissingItemsOrBOMs) THEN
      SetRecursiveLevelsOnBOM(CompBOM,LowLevelCode,IgnoreMissingItemsOrBOMs);
      END
      END;
      UNTIL ProdBOMLine.NEXT = 0;
      ...
