There is a custom attribute of data type multi-value lookup, in the Resource object. How can we bulk update values against this attribute for multiple instances of Resources at once?
The rsm_resources_read.xml can be used to obtain a sample XOG of a Resource instance (after that instance is populated with a value against the multi-value lookup attribute in question). This can then be used as a reference template to update other Resource instances. rsm_resources_write.xml can also be used for reference.
