expedition使用REPORT writer的时候出错，请高手指点

expedition中，点report writer‘进入的时候，就出错，提示：error Importing Files， check log file dbcreate.txt for details.
检查dbcreate.txt,发现提示如下：
  Importing TPadStackHoles Data
    Importing TPadStackPads Data
    Importing TPartNumber Data
ERROR :  3163 - The field is too small to accept the amount of data you attempted to add.  Try inserting or pasting less data.
