You are trying to adjust the width of columns on Fiori UI based on percentages, but this is not working when using a PDI.
SAP Cloud for Customer
Reproducing the Issue
- Go to your PDI solution using SDK.
- Open any screen that you want to modify the column width using Percentage values.
- This is not working.
- On HTML5 this works fine.
Fiori does not support Percentages due to technical reasons.
You should need to use Pixels to adjust the desired screens.
Note that the FieldWidth property on UI Designer has control only over columns in a table.
For custom fields the system behavior is to set the width for full screen, and currently there is not way to change it for Fiori UI.
