SAP PI: File/FTP Adapter - Large File Transfer (Chunk Mode)Background. Whenever large (binary) file needs to be transferred by using PI, there might be a chance for Out of Memory error which might results in server restart. Each chunk will be processed as an individual XI Message in sender adapter and all the chunks are combined based on the sequence in receiver adapter. Since all the chunks have to be combined in the actual order, Qo. S EOIO has to be used to enable this feature. Configuration Options. Select 'EOIO' as a Qo. S under Processing tab. After that select 'Advanced Mode' under 'Advanced' Tab. Option 1. You can choose the required chunk size option from the given list of 1, 2, 5, 1. MB. Option 2. Custom values which are not possible in default options can also be configured in additional parameters. Parameter Name. Possible Valueschunk. Mode Non emptry string will be considered as truechunk. Size. KBPositive Numeric Value. Processing in Sender Adapter. Dear SAP Community Member, In order to fully benefit from what the SAP Community has to offer. File content conversion. Basic Mode will be enabled only if Qo. S is EOIOChunk Mode related Advanced Mode parameters will be ignored if Qo. S not EOIOIf chunk. Size. KB is not defined /incorrect value, default is 1. KBIf both are configured, Basic mode will have higher precedence. Sender Adapter will create XI message with additional dynamic headers for each chunk and forwarded to Messaging System for IRD processing. Example. For this example, chunk size is configured as 2 MB and the below input file (~4. MB) is used. For demo purpose and to identify/analyze how the actual split happens, the input file is created with the data like below ( 1 to 6. As per the configuration, three chunks should be created with the size of 2 MB, 2. MB and ~5. 00 KB. Chunk 1 (2 MB)Transferring first 2 MBChunk 2 (2 MB) Transferring next 2 MB (Total 4 MB)Chunk 3 (~5. KB)Transferring the remaining ~5. KB (Total ~4. 5 MB)Dynamic Headers. Header. Value. Chunk. Start. Start of the Chunk (Position of bytes)Chunk. Mode. Active/End. Chunk. Key. Unique Key (Same for all the chunks for a particular file) The corresponding screenshots for all 3 chunks are given below. First Chunk. Next Chunk Last Chunk. If multiple files sent from different file sender channels, receiver adapter uses the chunk key to identify the proper output file(for combining). During the creation(and append) of output file, it uses the chunk key like below. In Temp mode, the temp files won’t be deleted till the last chunk is received. Overall Control Flow. Recovery Mode. If the input file is very large, it would normally take more time to be transferred completely. It's just a binary split. So the following limitations would apply. Only for File Sender to File Receiver. No Mapping. No Content Based Routing. No Content Conversion. No Custom Modules. How to choose the chunk size? Smaller chunk size ensures more reliability? Yes. Smaller chunk size creates more chunks (more XI messages). File Receiver with Content Conversion. Scenario: This scenario describes the steps involved in configuration of the receiver file adapter with file content conversion. File Content Conversion Scenario Input Message: This is the input message to the receiver file adapter sent from XI. Input XML message Output Message: Fig. Output CSV Message Steps: XI sends a XML message as input to the receiver adapter. Now this XML needs to be converted to a File in CSV format, i. To generate the required output, the data type at the receiver& #1. The data type should abide to the rules of well formed XML. The Receiver File Adapter is configured, using the following settings: Choose File Content Conversion as the Message Protocol. You may or may not give the & #1. Header. Line& #1. For the & #1. Separator& #1. For eg: it may be a & #1. The & #1. 45; end. Separator& #1. For eg: it may be a & #1. Fig. 4. Conversion Parameters in Adapter. Activate all the settings. Receiver File Adapter with F.
