Creating a TO Without a Source Document 
Typically you do not use source documents to create transfer orders when you transfer goods from one storage bin to another storage bin within the same warehouse. This is also true for any transfer that is carried out first in WM and then later reported to IM, such as transferring pallets from production into the warehouse.
The procedure for creating a transfer order without a source document is the same as the procedure for creating an order with a source document, with one exception. You must manually enter the information that normally is contained in the source document.
To create a transfer order without a source document:
Depending on the movement type, you may have to enter the requirement tracking type and number.
You continue the processing as if you were creating a transfer order based on a transfer requirement with a single item.
To continue, see the options for stock placements and stock removals under Creating a Transfer Order for a Transfer Requirement Manually.
