Magento 2.3.4 Configurable Products Issue

[c1oudmedia]

Magento 2.3.4 mariadb 10.2 php 7.2

simple products already set up with various options per simple product

requirement:

create a configurable product based on 1 attribute, in this case frequency, either uhf or vhf

the simple products have the attribute set

process:

set up configurable product - create configurations based on this attribute and create 2 x simple products

all fine to this point

now i want to manually add the existing simple products

this can also be done by replacing the auto created ones

Problem: when you then save the configurable product with the manually added products it saves and removes the manually added products therefore no products are associated to the configurable item

import doesn't overcome this issue either even when using sample csv to test

Desired Outcome if we can find a fix:

Create the configurable item as above

then on the frontend, see the configurable product,

then the user selects either uhf or vhf and the associated simple product options are displayed so the user can then check out

other thing to note:

if we save the configurable product with the auto generated simple products we can see the results on the frontend

however when you go into the auto created simple product and make any text or option additions/changes, the simple product is removed from the configurable product

Hello @c1oudmedia 

Please check if the attribute set in simple product and configurable is same.

The issue can be caused if it is not the same.

Hope it helps.

Apologies for the late reply

the issue still persists

i can create a configurable product and save it and it generates new products via the Create Configurations

the moment i change the created products for an existing simple product the products disappear from the configurable product

i tried going into the newly created simple products and adding text to description, adding a product option etc.. but again the moment you change anything they disappear from configurable product

I'm baffled

for something that seems so easy is proving a real headache

i found a post saying to create a new Attribute set for the configurable product but that doesn't work, choosing the same product set doesn't work

any ideas anyone

We also have problems with configurable products since the last update to 2.3.4.

For many attributes, no selection options are displayed, even though products exist.

On our staging system with version 2.3.3, these problems do not exist yet.

When will the problem be fixed?

Same here (Magento 2.1 - 2.2 - 2.3), did you find a solution ?

I have a solution for you that isn't another question...

I was having the exact same issue today - the simple product association wasn't saving when I saved the configurable product.

For me, it was because the simple product I was trying to associate had custom options assigned to it already. I removed these, retried and it saved!

Hopefully this helps someone.
