Looking for a source code on the below Matrix Import scenario packages,

Since we are facing an issue with validation of UOM between parent and child where the Acumatica allows to map the template items irrespective of UOM in below mentioned,ImportMatrixItems2022R2 (

But it is not allowed to do in 24R1 where Acumatica is not designed with out validation,

I would like to compare the code between the packages to overcome the validation which is not happening in 24R1.
