Quality of Service can be Best Effort (BE) – synchronous, Exactly One (EO) – asynchronous or Exactly One in Order (EOIO) – asynchronous with messages arriving in order.
Trigger mode defines the activation mode of the message collection. “Trigger by polling” means that every certain time the adapter channels search files to be processed in the corresponding file systems. “Trigger by file” means that a particular file must be present to process the specified files. Different trigger modes are:
Trigger by polling: The files are processed every certain time, which is previously parameterized.
Trigger by polling and by file (one trigger file per file): The files are processed every certain time, which is previously parameterized, if and only if the specified trigger file is present for each file. If the trigger file is not present, the file will not be processed and will be ignored.
Trigger by polling and by file (one trigger file per all): The files are processed every certain time, which is previously parameterized, if and only if the specified trigger file is present. In this case, only this file must be present to process all files that comply the criteria for selecting files to be processed in the channels. If the trigger file is not present, the files will not be processed and will be ignored.
Polling interval to collect files.
File processing mode. There are 3 pre-established modes to process the files collected by the adapter:
Test – Collects the files from the directory and creates the respective messages to be processed in SAP NW PI, but the file is not deleted from the directory so in the next poll it will be processed again. If the message processing is configured with a trigger file and/or a signature file and/or a checksum file, these files will not be deleted either.
Archive – Collects the files from the directory and creates the respective messages to be processed in SAP NW PI. The file is deleted from the source directory but it is archived again in the configured directory of the file system of the configured SAP NW PI or in the directory of the file system of the configured SFTP server. When the file is deleted from the reading directory of the channel, this file will not be found in the next poll. This mode controls the file name so the “message system” of the AAE will not allow processing a file with the same name. If the message processing is configured with a trigger file and/or a signature file and/or a checksum file, these files will also be archived. There is an exception, if the check “Delete Trigger File” is activated the trigger file will be deleted.
Delete – Collects the files from the directory and creates the respective messages to be processed in SAP NW PI. The file is deleted from the source directory. When the file is deleted from the reading directory of the channel, this file will not be found in the next poll. This mode controls the file name so the “message system” of the AAE will not allow processing a file with the same name. If the message processing is configured with a trigger file and/or a signature file and/or a checksum file, these files will also be deleted.
The empty file processing, with the following options:
The file is collected but a message is not created in SAP NW PI (Do Not Create Message).
The file is collected and an empty file is created in SAP NW PI (Process Empty files).
The file is ignored, is not collected and no message is created in SAP NW PI (Skip Empty Files).
The archiving of messages with errors. A directory of the file system of SAP NW PI can be configured, where the files collected by the adapter are stored and whose processing in the "module processor" threw an error.
Definition of the file type being able to define if it is a binary or a text type.
The parameters to define these functional aspects are:
