4. Example : ENDPOINT : /rest/V1/carts/mine/items TYPE: POST REQUEST: { "cartItem": { "qty": 1, "quoteId": "99264", "sku": "testbund2", "product_option": { "extension_attributes": { "bundle_options": [ { "option_id": 9, "option_qty": 1, "option_selections": [ 17 ] }, { "option_id": 10, "option_qty": 1, "option_selections": [ 18 ] }, { "option_id": 11, "option_qty": 2, "option_selections": [ 19 ] } ] } } } }

Expected result

{ "item_id": 86590, "sku": "testbund2", "qty": 1, "name": "Bundle product 2", "price": 4705, "product_type": "bundle", "quote_id": "99264", "product_option": { "extension_attributes": { "bundle_options": [ { "option_id": 9, "option_qty": 1, "option_selections": [ 17 ] }, { "option_id": 10, "option_qty": 1, "option_selections": [ 18 ] }, { "option_id": 11, "option_qty": 2, "option_selections": [ 19 ] } ] } } }

Actual result

{ "item_id": 86590, "sku": "testbund2", "qty": 2, "name": "Bundle product 2", "price": 4705, "product_type": "bundle", "quote_id": "99264", "product_option": { "extension_attributes": { "bundle_options": [ { "option_id": 9, "option_qty": 1, "option_selections": [ 17 ] }, { "option_id": 10, "option_qty": 1, "option_selections": [ 18 ] }, { "option_id": 11, "option_qty": 2, "option_selections": [ 19 ] } ] } } }

Additional information

So, whatever the last option qty we have set, it reflect the same for main bundle product .i.e parent bundle. In the above example, I set the last option product qty as 2, so it is adding 2 bundle product in cart.

Hi @lokborn

Thanks for reporting and collaboration.

It is not advisable to disable the MSI modules.Can you please provide the use cases for which you need to disable the MSI modules.

Hi @engcom-Dash

I have disabled all MSI modules as we do not need multiinventory setup in our case. Also, it improves the performance of multiple APIs.

Hi @lokborn

Thanks for reporting and collaboration.

As per the adobe dev docs, Disabling the Inventory Management modules can cause an unstable system and result in various issues.

Please refer the below devdocs for more information :
