@sachin_32 You can accomplish by utilizing the "Advanced UI" capability found in the UpdateAttribute processor. The advanced UI allows you to create Rules (think if these as an IF/Then capability). So you would setup 3 rules: 1. If current date falls on Mon - Fri, do X 2. if current date falls on Sat, do nothing 3. if current date falls on Sun, do Y Expression Language guide Below you can see I have created 3 rules (Day1-5, Day6, and Day7) Once you create a Rule, you need to provide a Condition (This is your boolean if statement) In this case I am using it to figure out what the current day of the week with 1= Monday and 7 = Sunday and seeing if the day of the week is prior to Sat or after Sat in the current week. If a rules condition (if statement) resolves to a boolean "true", then the configured "Actions" (then statement) are evaluated. For my "Day1-5" rule, I set: Condition: ${now():format('u'):lt(6)} Action: ${now():toNumber():minus(${now():format('u'):plus(1):multiply(86400000)}):toDate():format("EEE, dd MMM yyyy")} For my "Day6" rule, I set: Condition: ${now():format('u'):equals(6)} Action: ${now():format('EEE, dd MMM yyyy')} For my "Day7" rule, I set: Condition: ${now():format('u'):gt(6)} Action: ${now():toNumber():minus(86400000):toDate():format("EEE, dd MMM yyyy")} About above: - The "now()" function returns the current date. - 86400000 is the number of milliseconds in 1 day. - So first I get the current date and convert it to milliseconds using the "toNumber()" function. - Then for Day1-5, I am subtracting based on current day of week a multiple of days worth of milliseconds. - For Day6, I am doing nothing other than reformatting the current days date. - For Day7, I am just subtracting one day or 86400000 milliseconds No matter which rule is applied the final date format i choose to write to an attribute named "PreviousSaturday" on the FlowFile is formatted using java simple date format "EEE, dd MMM yyyy" Example: " Sat, 05 Mar 2022" If you found this response assisted with your query, please take a moment to login and click on "Accept as Solution" below this post.
