I need help about flat file uploads.
We have flat files, which are periodically prepared by users and left to a <b>FTP</b> folder. Than all files at this FTP server are automatically copied to <b>BW application server</b>, so that process chains can reach these files.
However, users sometimes leave related files later than the specified time on process chains. This causes upload errors in ODS and Infocube requests.
To prevent this, I'd like to check if a file exits in App. server.
When exists continue to trigger infopackage, else stop processing process chain.
So.. How to make this "<b>file existance check</b>" ?
ABAP ? Then how ? Else, then again how 😊
Any hints will be appreciated.
