Summary:

I am trying to make a table validated value set based on another EFF segment in the same context, but I am getting The bind variable does not refer to an existing segment or value set. (FND-2634)

Content (please ensure you mask any confidential information):

I have a context with api name "General" and a segment with api name "officialNumber".

According to the documentation https://docs.oracle.com/en/cloud/saas/applications-common/25c/oaext/considerations-for-managing-extensible-flexfields.html#s20030925

• :{CONTEXT.<context_code>;SEGMENT.<segment_code>}: Identifies a segment in a different context. The context must be in the same category or in an ancestor category, and it can't be a multiple-row context.
