text: Each group is surrounded by BNG/ENG Structured Fields, and each group contains TLE 
  Structured Fields that occur after the BNG but before the BPG. 
  
  When an input file contains TLE Structured Fields, do not specify indexing parameters, such 
  as**TRIGGER**,**FIELD**, or**INDEX**. They are not needed because the file already contains index 
  information. 
  
  ACIF processes a file that contains TLE Structured Fields in the following way: 
  
  1. For every BNG in the input, ACIF creates a group IEL Structured Field in the index file. 
  
  2. ACIF makes a copy of the TLE Structured Fields from the input and places them into the 
  index file. The original TLE Structured Fields are also placed into the output file. 
  
  If the input file does not contain the correct number of TLEs in each group, ACIF might 
  complete, but**arsload**might fail with the following message: 
  
  *“x*fields submitted,*n*expected” 
  
  The*n*is the number of fields that are defined to Content Manager OnDemand. 
  
  After ACIF processes an input AFP file, the output file might be larger than the input file, even 
  if the input was an AFP file. The answer is because ACIF changes the AFP, “improves it”, and 
  usually increases the file size. The following changes are made to the AFP: 
  
  (cid:2) Creating or adding comments to the BDT Structured Field 
  (cid:2) Creating or adding group names to the BNG - ENG Structured Fields 
  (cid:2) Changing obsolete Structured Fields to current Structured Fields (for example, MCF1 to 
  MCF2, or PTD1 to PTD2)
