PCM - Push the GRP from esponsor tables to brand field when creating PCM incidents

Problem Statement

When creating a PCM from the esponsor exception, right now no brand is sent across automatically. We need to use the GRP code present in those esponsor views to automate the brand field population when creating the PCM ID

Acceptance Criteria

GRP code from esponsor is used to populate the brand field when a PCM ID is created.
