 -> A retry can be written in a catch block to jump back to the first line of code within the try block.  -> This can be used if the issue in the implementation can be fixed by code in the catch block. -> Then, the try block will run again to give it a second chance to succeed.  **** -> Make sure that the retry does not cause an infinite loop.  Example: try { //Run some code that might throw a numeric or other type of exception. } catch (Exception::Numeric) { info('Found a Numeric exception.'); } catch { info('Caught an exception'); retry; } finally {         // Executed no matter how the try block exits. }

 RecordInsertList class to copy a bill of materials (BOM) from one BOM to another. Ex: void copyBOM(BOMId _FromBOM, BOMId _ToBOM)  {      RecordInsertList BOMList;  // This is recordinsertlist     BOM BOM, newBOM;      BOMList = new RecordInsertList(tableNum(BOM));      while select BOM      where BOM.BOMId == _FromBOM      {          newBOM.data(BOM);          newBOM.BOMId = _ToBOM;          BOMList.add(newBOM);      }      BOMList.insertDatabase();  }
