I have a tough question here: I have created a Workflow that allows me to check data for various conditions using rule engines. However, I have run into an issue with this. Some of the files do not have all of the headers I have created in the rule engine. This is causing the rule engines to fail and the process to stop. I think an example may be helpful for this issue.
Let’s say in any given file, I may have three columns, “A,” “B,” and “C”. I have to have rule engines on to check certain parameters on all of these columns in case a file is submitted with all three. However, there are some instances in which a file is submitted and only columns A and B are present. Thus, the rule engine for column C fails. I want to make it so that I can bypass the rule engine for column C and give an output file.
Thanks for the help. Do you know of any way that I could make it just skip a the rule engine node if necessary? The hope is that I can avoid creating customized flows for each file as it seems might be necessary with the case switch data nodes.
Perhaps instead of using a Rule Engine node, you could employ the Java Snippet node to set up more sophisticated if-then structures. E.g., if column A exists, then check the parameters; if not, move on to check column B, etc. Here’s an example workflow highlighting several different functions:
