    • You must configure SAP ECC RFC account and obtain SAP proprietary JAR files and other required files to fulfill a Spoke requirement.

    Contact the admin of your SAP ECC RFC account and obtain these SAP proprietary JAR files and other required files:

    • sapjco3.jar.
    • libsapjco3.so: If your MID Server is installed on a Linux machine, obtain this file.
    • sapjco3.dll: If your MID Server is installed on a Windows machine, obtain this file.

    A JAR file, sapConnector-1.0.1.jar, is available along with the spoke to provide custom interface to interact and execute RFCs and IDocs in the SAP ECC RFC account. The JAR file is installed as part of the spoke in your ServiceNow instance.

    Copy and record the client value of the target host where the SAP ECC RFC server is installed.

    Configure the values of these system properties:

    • com.snc.process_flow.reporting.serialized.val_size_limit: This property serializes JSON objects and ensures that the data is in the required format. Specify the number of bytes as per your requirement. For more information, see 
    • glide.rest.max_content_length: This property specifies the payload size. Specify the maximum payload size you want to use in your flows. The maximum value you can specify for this property is 25 MB.
