I have a workflow where the desire is to filter out null values for fields with data but also retain fields where all values are null. Using the attached workflow, fields 1 - 3 have a combination of actual values + null values while field 4 only has null values. I've succeeded in stripping out the null values for fields 1-3 but in the process, I lose field 4 at the very end. How do I reinstate field 4 in the final output? It might be worth noting these results can change month over month. So next month, I might have all null values in multiple fields and would need these to be reinstated in the final output. Any suggestions?
