Operators AND - OR in Nested IF

Framet

Many thanks for your advices.

I tried to split in 4 different columns. Doing  that I realized that 1st IF should have a differente logic:

IF (
    ZV[OrgCom] = "CUSTORG"
        && ZV[IDCust] = "491"
        && ( ZV[IDDel] = "SPD99"
        || ZV[IDDel] = "WAR99"
        || ZV[IDDel] = "DPD99"
        || ZV[IDDel] = "FOC99"
        || ZV[IDDel] = "KBD99" )
        && (ZV[CounFinGood] <> "MX"   
        && ZV[CounFinGood] <> "RU"
        && ZV[CounFinGood] <> "AR"
        && ZV[CounFinGood] <> "CN");

    "1CS";

Now I have changed the orginal long formula and  it is ok.

Thanks again.
