Hi Ibrahim,
In additional parameters in the adapter configuration, set the Advanced Mode indicator.
- Msecs to Wait Before Modification Check
Enter the number of milliseconds that the adapter must wait before it checks whether the files have been changed.
This parameter is not available if you have selected File Content Conversion as the Message Protocol and then made an entry under Recordsets per Message that splits an input file into several messages.
This parameter is applicable only for the File adapter. If you enter a value in this field when configuring the sender FTP adapter, it will have no effect.
