Hello Team, I am very new to alteryx workflow design and I am stuck in process.

1. In the above dataset in description column I have to look for 3 keywords Depr or Depreciation, Interest Income and Interest Expense replace null values in Category column with Deprecation, Interest Income and Interest Expense and keep all other fields blank.
2. Once above step is done I have to combine data of Category Column and Comp Code Column without an space in join column without affecting original data.
3. After that I have to fill Currency and Tax owner column using a function similar to v-lookup in excel with the help of another input file (below screenshot) and the lookup reference will be comp code col.

Can someone please help me with the process.
