changed permissions for user sapserviceSID do not take effect in file sender CC
I have a case, where PI needs to pick up a file from a folder on another server. I create a file sender CC and make sure, that the user "sapserviceSID" has access and sufficient permissions on that folder. I can access the folder using the user sapserviceSID from the server where PI is installed but in the channel monitor I get an error saying, that the folder does not exist.
I have heard something about, that added permissions to a folder/server do not take effect if there already is established a connection from PI to that server/folder. Is that correct? How can I fix this problem so that the new permissions for user sapserviceSID take effect in the CC?
