Assigning a MOVE
You use the MOVE rule to specify that the ABAP move command is used to transfer the data. This has the following results for source fields that do not have the type C or N:

The
system always defaults a MOVE processing when you assign a source field to an
SAP field. 
You do not have to explicitly assign a MOVE processing unless you selected a different type of processing and, finally, decide to use a MOVE after all.
A source field must have been assigned to the SAP field.
1.
From the list
of steps, choose Maintain Field Mapping and Conversion
Rules.
A screen
appears.
2. Position the cursor on the corresponding field.
3.
Choose MOVE.
The processing type
is displayed.
Alternatively, you can also choose Insert rule and set the indicator
for Move.

If, in the third step, you choose the indicator for not initial in addition to the indicator for Move, the data will only be transferred in case if the source field does not contain the initial value.
