Not able to select Base unit in Receipt from production and Sales order

Question

Can anybody help me out for the below scenario
I have defined Sales UOM , Sales Packaging UOM, Items per Sales unit and Quantity per Packing UOM  for all finished product in the item master.
I have created Production BOM and Production Order (with Issue method is Manual because they maintained items batchwise ) for all Finished products. 
Based on Production orders, I received finished products(Batch wise) through receipt from production.  But the base unit shows Yes and it is not allow me to change. 
In Sales order, the quantity column shows the value of quantity per packing UOM instead of Items per sales unit. 
For Ex. ItemA - 01 No (Item per Sales Unit)
                         3600 Pcs ( Quantity per Packing UOM)
                         Receipt from Production - 10 Nos
                         In Sales order - it shows 36000 (10*3600 ) instead of 10 nos
Expecting favourable solution for that.

Answer 1

The selectable units on the sales order are the inventory unit or the sales unit. So if you want to see in units of 3600 Pc-s you should define this as Sales Unit (not as packaging unit). Then you can show the item in this unit in the sales documents.
(In the receipt from production document you should always use the inventory Uom.)
