What do you need help with?
I have a single table named “Companies”.
It contains a “Link to Table” field with a reference to a supplier, which is linked to their customers.
I created a small application that displays a list of a company’s customers in a table.
I want to add a “Delete” button to remove the link.
I tried to create an event that updates the cell containing the list of IDs, without including the row ID. Unfortunately, I end up with commas… (see screenshot of the table)
What is the recommended way to implement “remove link-to-table” in App Builder ?
Please attach screenshots or videos if they help illustrate your question.
I understand that what was expected was the line name (and not the ID). But the problem remains the same 
I found a formula thanks to ChatGPT, do you have a better solution?
replace(
replace(
replace(
get(‘current_record.field_476651.*.value’),
concat(get(‘data_source.1413594.field_264793’), “,”),
“”
),
concat(“,”, get(‘data_source.1413594.field_264793’)),
“”
),
“,”,
“,”
)
@frederikdc Maybe you have a better solution for this? 
There are 2 ways to implement adding or removing items from a Link to table field in the app builder.
- Use the Record selector element and make sure it allows you to select multiple items.
- Reorganize your tables you that you have an intermediate table where each record links 1 supplier to 1 customer. This makes is much easier to add / remove records by using a Repeat element.
If input will be done mainly by the application builder, I would recommend the second approach.
Thank you for your reply. I used the second approach and it works very well.
Have a good day!
