Layer cost update

Hi ,

We have 150+ Inventory organizations with FIFO costing and have a business requirement to maintain a constant item cost for few selected items , to achieve this we are planning to update the layer cost to one value using open interface  ie insert records into interface table “MTL_TRANSACTIONS_INTERFACE” and “MTL_TXN_COST_DET_INTERFACE” with transaction type as Layer cost update

We did a POC in our development instance and was successful and worked the same way as the Layer update FORM does

Question : Has anyone from our team has used the above approach for updating layer cost and faced any challenge after implementing it
