Here is an example of an interface that was done for a specific client. The load file is a fixed format, and is used to load employee elections and component amounts into [IBEL].

||Rec\\#||Field\\#||Name||Beg\\Pos||End\\Pos||Constant\\Value||Derivation\\Expression||Notes
|0| 0| HEADER RECORD*| 0| 0| | | Since there is 1 header record in the file, one field must be defined in the interface for the header record.
|1| 1| BEL.BPN_ID.PLAN_CODE| 3| 15| |{{{P2K_SMGLX('GWRS_PLAN_TRNSLT',~)}}}|The derivation will translate the policy number in the file to the plan code using a user defined lexicon.
|1| 2| BEL.EEM_ID.EID_ID.PERSON_CODE| 46| 55| |{{{ LTRIM(~,'0')}}}|The person code will be trimmed of any leading zeros.
|1| 3| BEL.ELECTION_STATUS| -1 |-1| 00| | The election status will be hard coded to Not Yet Elected, LBEN will then elect and enroll the employee. Since this field does not have a value within the file, it has been defined with -1.
|1| 4| BEL.BCG_ID.COVERAGE_CODE| -1| -1| |{{{ P2K_SMGLX('GWRS_PLAN_TRNSLT',~)}}}| Since both coverage code and plan code are the same for these plans, the derivation expression from plan code field may be used. Since this field does not have a value within the file, it has been defined with -1.
|1| 5| BELC.BBC_ID.BC_CODE| -1| -1| B1000| | Hard coded to B1000 so the system know which BC Code to update. Since this field does not have a value within the file, it has been defined with -1.
|1| 6 |BELC.AMOUNT_OVERRIDE |120| 123| |{{{ TO_NUMBER(~)/10}}}|This field will pick up the amount from the flat file.
|1| 7| BEL.F_QUALIFIER*** |-1| -1| TRUE| {{{ CASE when 
(:BEL.BPN_ID.PLAN_CODE) ='99999-05' 
then 'FALSE' 
when (:BEL.BPN_ID.PLAN_CODE) =
'99999-02' 
then 'FALSE'
 else 'TRUE'
  end }}}|This derivation will ensure that if the wrong file is selected (i.e.: file for 401A policies) the records will not qualify. The records will only qualify if the value in the BEL.BPN_ID.PLAN_CODE field does not match 99999-02 or 99999-05.
|2| 0| TRAILER RECORD**| 0| 0| | | Since there is 1 trailer record in the file, one field must be defined in the interface for the trailer record.

;:*Record 0, Field 0 must have a Record Type of 'Header Record'
;:**Record 2, Field 0 must have a Record Type of 'Trailer Record'
;:***Record 1, Field 7 must have a Record Type of 'Qualify Record'
