Correcting a Record

The Correct action allows you to update the information of an erroneous record. After correcting the records, make sure to select them for reprocessing. See Reprocessing a record for more information. 
There are two ways to correct records:

• Simple Correction
• Advanced Correction

Select the record(s) you want to correct and click Correct.

Simple Correction

In the Correct Panel:

1. Select the target field of the record that you want to correct. If the field is missing from the record, you can add that field using the Add Field option.

You can do an advanced level of record correction by creating a desired expression with pre-defined functions or fields. The field you want to correct is updated with the output of the custom expression. Click on the Guide banner to see a brief explanation of all available functions. 

To apply the advanced correction:

1. Turn on the Use expression toggle.

2. Select the field you want to correct from the Target field drop-down list. If the field is missing from the list, you can add that field using the Add Field option.

3. Create the target value by selecting from the available fields, using pre-defined functions, or combining both. This action constructs the expression template in the Expression textbox.

4. Customize the template to match your specific requirements.
   The following table provides the list and description of the pre-defined functions provided in the Guide banner:

   Mathematical Function	Description	Example
   Numeric functions
   Floor	Rounds down to the nearest integer or lower.	floor(3.8) = 3
   Ceil	Rounds up to the nearest integer or higher.	ceil(3.8) = 4
   Round	Rounds to the nearest integer or decimal places.	round(4.7) = 5
   Addition	Adds two or more numbers.	5+3 = 8
   Subtraction	Subtracts one number from another.	10 - 6 = 4
   Division	Divides one number by another.	10/5=2
   Multiplication	Multiplies two or more numbers.	5*3=15
   String functions
   Uppercase	Converts a string to all uppercase letters.	upperCase("hello") = "HELLO"
   Lowercase	Converts a string to all lowercase letters.	lowerCase("WORLD") = "world"
   Trim	Removes leading and trailing spaces from a string.	trim(" example ") = "example"
   Concatenate	Joins multiple strings together.	concatenate("Hello", " ", "world") = "Hello world"
   Slice	Extracts a portion of a string by specifying the start and end. slice (x,y): get the substring of x, starting at index y (y = 0 is first character) slice (x,y,z): Get a slice of z characters from the string x, starting at index y (y= 0 is the first character)	slice("abcdef", 1, 3) = "bc"

   
   
   

   Info

   Examples: If you want to round down the field 'price' from its original value of 1.001 to 1, select the floor function from the Add function dropdown list and then select the field 'price'. Expression will be: floor(@{payload.price}) If you want to convert the value of the field 'model' to uppercase then the target field and the field selected in the Add field dropdown will be the same and the function will be Uppercase. Once a selection is done, you will see a template expression created like this: upperCase(x)@{payload.model} where you need to update the expression to upperCase(@{payload.model}).

5. Since a correction cannot be undone, it is recommended that you test the expression on one single record before doing a bulk change. Click Apply to correct the selected records. You can also select the reprocess checkbox in the confirmation box to reprocess these corrected records.

Reprocessing a Record

reprocess reprocess

The Reprocess action enables you to reprocess records by sending the corrected records back to the Validate Function where they are re-validated and once successful, they are forwarded downstream. While the records are being reprocessed they are not available for correction or deletion. If the record failure is a result of a temporary issue or misconfigured validation, you can reprocess it without making any corrections.

Deleting a Record

The Delete action provides the option to remove a failed record from the system. When you click the Delete option, a confirmation prompt appears to ensure that you want to delete the selected record(s).
