Is a part of? keeps disabling by itself.

[fedeyobe]

Hello, how are you? I have this problem:

In a table i have three ref columns, only two should have the "Is a part of?" enabled. 

One of them works fine. But the second one keeps disabling by itself, so, it works for one time (the form is shown inside another form), then i reload and it goes back to disable. 

Anyone knows why this is happening?

A child can only be "isPartOf" a single parent.

Hello @Marc_Dillon, thanks for your answer.

If you check in this answer from Aleksi https://www.googlecloudcommunity.com/gc/AppSheet-Q-A/IS-part-of-not-working/m-p/238584/highlight/tru... 

he says it's possible to have more than two childs in a table. 

Do you think this is still like that? could be another workaround?

Regards,

Federico.

One record can be referenced by any number of other records or tables (1 parent with many children)

One record can reference any number of other records or tables (1 child with many parents)

But only a single Ref column in a table can be set as isPartOf.
