Problem adding components to production order using CO_XT_COMPONENT_ADD

Hi experts,

I need to add components to production order. Before doing that I delete an existing component using:

CALL FUNCTION 'CO_XT_COMPONENTS_DELETE'

CALL FUNCTION 'CO_IT_SET_FLG_ITAB_NEW'.

CALL FUNCTION 'CO_XT_ORDER_PREPARE_COMMIT'.

COMMIT WORK AND WAIT.

Then, if I have deleted position 0020, I need to add a new component in that 0020 position with function CO_XT_COMPONENT_ADD I get error X4017 (Component &1: Operation not found in order &2). Is there any posibility to add component in the same position I have previously deleted ?

Thanks in advance.
