Using Open Batches
The open batch functionality is used to read file-based data sources and import them into the appropriate POV based on the file name. It is a batch definition type that enables you to automate and schedule the workflow process (such as four fish steps in the Data Load Workbench: import, validate, export, and check), particularly when you must process the loading of a large number of external files. Open batches cannot contain jobs. Additionally, open batches can be scheduled to run periodically.
The high-level process overview of the Open Batches function consists of:
- 
                        In Batch Definition, add a new batch definition with the type of Open Batch. 
- 
                        Create an openbatchfolder in the applicationinbox\batchessubdirectory where the files to be imported are copied.After a batch is processed, a directory is created and all files within the OpenBatchdirectory are moved into it. The new directory is assigned a unique batch ID.
- 
                        Select the File Name Separator character. This character is used to separate the five segments of an open batch file name. 
- 
                        Select the Auto Create Data Rule option. 
- 
                        Stage the open batch files by copying files to the inbox\batches\openbatchfolder using the name format for batch files.
- 
                        In Batch Execution, process the batch.
