Hi Venu,
you may use the following SAP help available for configuring your receiver File adapter with FCC:
Configuring the Receiver File Adapter - Advanced Adapter Engine - SAP Library
for FCC parameters for your structure containing two sub structures, you will have to define them for both the nodes:
RecordSet Structure : record, empdetails, company
empdetails.fieldNames : empname, empid
empdetails.fieldFixedLengths : 7, 5
empdetails.endSeparator : 'nl'
company.fieldNames : companyname, companycode
company.fieldFixedLengths : 10, 10
company.endSeparator : 'nl'
Regards,
Faisal
