checkbox have only 2 values : space or 'X' ... to create into the BAPI a field or structure whit these values you must create o assign a estructure like, for example, a BAPI_MARAX-DEL_FLAG ... look at BAPI_MATERIAL_SAVEDATA ....

Hello Amit

BAPI are usually well-documented, e.g. PLANTDATAX of BAPI_MATERIAL_SAVEDATA:

 Information on update for PLANTDATA
 Description
     This (checkbox) structure determines which fields in the assigned user
     data structure (PLANTDATA) contain change-relevant information.
     This makes it possible to supply valid values only to the relevant
     fields in the assigned user data structure. These fields are then
     selected in the checkbox structure, ensuring that all nonselected fields
     retain their current value in the database.
     All fields in the structure use the data element BAPIUPDATE.

Documentation for BAPIUPDATE:

 Updated information in related user data field
 Definition
     This flag is used to select fields containing modified values in the
     parameter. It is used in, for example, change methods.
     The value 'X' means that the associated field contains an updated value.
     The value BLANK means that the field does not contain an updated value.
 Conventions for Parameters with Updated Values (update parameter)
     The parameter has exactly the same fields as the parameter with the user
     data. The name of the update parameter should consist of the user data
     parameter name with an additional 'X'
     For example: User data parameter name:       Equisales
                  Update parameter:               EquisalesX
     If the parameter is a table the update parameter must also be a table.
 Example
     The distribution channel (Distr_Chan) should be changed to the value
     'US'.
     Business Object:                 PieceOfEquipment
     BAPI:                            Update
     Parameter with updated data:     EquiSales
     Fields in EquiSales:             SalesOrg
                                      Distr_Chan = 'US'
                                      Division
                                      ...
     Parameter for modified data:     EquiSales_x
     Fields in EquiSalesX:            SalesOrg
                                      Distr_Chan = 'X'
                                      Division
                                      ...
     In the parameter EquiSales_x the field Distr_Chan has the value 'X',
     meaning that the field EquiSales-Distr_Chan contains modified values.
 Further Notes
     This procedure is necessary because otherwise fields containing updated
     values cannot be identified. Using an initial value is no solution
     because an initial value could also be valid new value. Also, in the
     ABAP programming language or on other development platforms, you cannot
     assign the value "zero" to a field in order to select fields and thus
     indicate that the remaining fields contain update values. For further
     information see the BAPI Programming Guidelines.
