Re: How to validate input subfile

["Stiju Easo" <stiju.as400@xxxxxxxxx>]

I have done with simple input subfile,
 durring validation
 readc can only read once
 If the user resubmits the subfile without giving valid values to the
fields( concider case he dont even change a recod) how can i ensure it gets
validated second time

 should i use read insted of readc?
 i dont know concept of MDT tag
 can u explain how to use it.
