Thank you Chris.

Thanks Chris.

As per the documentation, getAll is supported for the following records:

<simpleType name="GetAllRecordType">
        <restriction base="xsd:string">
            <enumeration value="budgetCategory"/>
            <enumeration value="campaignAudience"/>
            <enumeration value="campaignCategory"/>
            <enumeration value="campaignChannel"/>
            <enumeration value="campaignFamily"/>
            <enumeration value="campaignOffer"/>
            <enumeration value="campaignSearchEngine"/>
            <enumeration value="campaignSubscription"/>
            <enumeration value="campaignVertical"/>
            <enumeration value="currency"/>
            <enumeration value="leadSource"/>
            <enumeration value="state"/>
            <enumeration value="supportCaseIssue"/>
            <enumeration value="supportCaseOrigin"/>
            <enumeration value="supportCasePriority"/>
            <enumeration value="supportCaseStatus"/>
            <enumeration value="supportCaseType"/>
            <enumeration value="taxAcct"/>
        </restriction>
    </simpleType>

I want to fetch all the data for either the customer or the vendor.

What am I missing?
