I am under the impression that there were Lookup_Hash tables but I just discovered that is not the case. Hash tables exist on Accounts, Contacts, Addresses and a few others. Hash tables normally help drive searches and increase responses to lookups. My mistake!
When one uses sp_CRM_WriteLookup to push a new lookup value in, one would assume that the indexes and the "pulldown abilities" are updated.
I understand the prior responses and have found that the values are put into the lookup table and next cycle INTO RedHorse, the values are indeed there. Would be nice to be able to see them without the restart but, for now we live with it that way.
Issue resolved unless there is a way to "see" those values in the lookups immediately.
