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.

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(~)/10This 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'
