We may have a use case to Hide relationship attribute as make it as view only by considering the value of one of the attribute(PRODUCT_TYPE) in the Parent(ITEM_HIERARCHY) Repository.

Suppose,We Have a Repository Called ITEM_HIERARCHY having Self Relationship Contains and ContainedBy along with a Relationship attribute as 'Quantity'.I need to make Quantity Attribute as value only or hide the same if PRODUCT_TYPE(One of the Attribute in Root Repository) value is 'EA'.

 

Make relationship attribute as view only or Hide by considering the parent repository attribute in a self relationship repository model.

ALL

To achieve this use case,We need to use below constraints in Relationship catalog(rct_*) to restrict the access mode of 'Quantity' Attribute.

<constraint>
    <name>PRODUCT TYPE Access Mode</name>
    <description>If Product Type is EA then the access for Quantity attribute is view only.</description>
    <condition>
        <eq>
            <var>PARENT/PRODUCT_TYPE</var>
            <const type="string">EA</const>
        </eq>
    </condition>

<action>
        <access mode="view">QUANTITY</access>
    </action>
</constraint>

With above constraint,we can make the Relationship Access mode to view only as below.




We can hide the Relationship Attribute by using below Constraint.

<constraint>
    <name>PRODUCT TYPE Access</name>
    <description>If Prodcut Type is EA then the access for contains Quantity to view only.</description>
    <condition>
        <eq>
            <var>PARENT/PRODUCT_TYPE</var>
            <const type="string">EA</const>
        </eq>
    </condition>

<action>
        <access mode="hide">QUANTITY</access>
    </action>
</constraint>
