[EXCEL] Custom Mapping Output not being available to be chosen

[Joker_Hazard]

Greetings friends.

I am trying to append some data to a custom range in Excel. However, the button for some reason is not available.

Some keypoints about my workflow:

1. I have 5 outputs for the same Excel file. (Cannot change that)  I'm using block until done tool.

2. Its an APP, not the usual workflow.

3. I cannot chose OverWrite File due to the other sheets.

Unfortunately I can't provide Alteryx Workflow due to compliance rules. I will try to provide as many screenshots as possible to help with the troubleshooting.

Thank you very much

I've just figure it out myself. Really naive mistake.

I was with the file open. Once I closed it, the button was available :)

I hope to help others with this post hehe
