Check Statement

Hi Forum,

Is the statement correct?

CHECK control_out-mestyp EQ 'INVOIC02' AND

control_out-cimtyp EQ 'ZXINVOIC02' AND

control_out-sndprn IS NOT INITIAL OR

control_out-mestyp EQ 'INVOIC02' AND

control_out-cimtyp EQ 'ZYINVOIC02' AND

control_out-sndprn IS NOT INITIAL.

Here i am trying to achieve eihter combination of invoice02 and zxinvoice02 or invoice02 and zyinvoice02.
