Dear varada rajan

It is normally not adviceable to convert from MTS to MTO, you can do so through MB1C by using Movement Type 521E where it will ask sale order number.

Give the sale order number, material code and quantity and save. Now go to MMBE and you can see that the quantity what you blocked in MB1C is shown against "Sales Order Stock". If you double click that, it will show against which sale order, the quantity is reserved.

As I understand, if the material is already in stock (Production Order MTS ), in order to assign the sales order, if we do MB1C using 521E, the stock will be duplicated as MB1C is for Initial Stock entry.

How to avoid this duplication?
