Does anyone have experience on AX7 Production orders data entity?

I created a production orders data entity, but when I tried to import the data, it always get a error relatated to  InventDimId.

If added the below highlight code line, the error message is "Insert not allowed for field 'ProdTable.InventDimId".

But if comment out the highlight code line,  the error message will be "Inventory dimension identification not specified."

Can anyone give me an idea on  this?

Thanks in advance.
