Data Mapping cfxdm - dm:fixcolumns
dm: fixcolumns: This dm function allows the user to remove the special characters like @,. (dot) etc from a column name. If there is a special character in between a column name, it replaces it with an underscore (ex: First. Last to First_Last)
dm: fixcolumns syntax: It doesn't require any arguments. Just ingest the data into this tag/function using a pipe (-->)
Example 1:
Default dm: fixcolumns functionality is captured in this example.
Step 1: Create an empty dm_fixcolumns_example_1 using AIOps studio as shown in the below screenshot.
Step 2: Add the following pipeline code/commands into the above-created pipeline as shown in the below screenshot:
You can copy the below code into your pipeline and execute that in your environment.
##### This pipeline creates a set of records/dateset details coming from a vCenter
##### environment. This dataset includes datastore details, Folder name, guest_hostname,
##### guest_ip_address.
###### This pipeline uses dm fixcolumns to fix the column names that has special
###### characters and replace with '_' character for other operations.

Step 3: Click verify button to make sure syntax and pipeline code is correct (as shown below)
Step 4: Click execute button and execute the pipeline. RDA will execute the pipeline without any errors (as shown below).
Step 5: RDA uses the dm fixcolumns function to replace special characters (dot, space, etc) with underscore character as shown in the following screenshot.
