We do a lot of interfaces using flat files on IFS (integrated file share on I series ) . For this we ask our system admin to create a folder share and allow csv .txt as valid file types and have encoding set to UTF8 . You can also have in jde for inbound files P93081 to set encoding . We have template UBE for inbound interfaces where we provide the path , then create path for IFS . Pls note windows path are like C:\XXX\YYY while on IFS the paths are /PY910/XXX/YYY , the direction of slash is the other side . Then we copy to import if we are using TC because TC cannot have dynamic path and so we let is read from import of the path code . If you use business function B34A1010 for open , write , close . Use B76B0220 and then get the entire record tuple . The use function like Parse delimited string to separate out data values from the record , validate and enter into staging and whatever after that .. Hope this guides a little
