Post Upgrade Error: No enum constant com.pega.pegarules.priv.database.sqlgen.constants.ColumnType.-9999
we are just in process of upgrading from Pega 7.2.1 to Pega 8.7.3.
During the revalidation we found have for some report definitions the error: No enum constant com.pega.pegarules.priv.database.sqlgen.constants.ColumnType.-9999
From what I can see it only occurs for the report definitions that are using declarative index joins (snip attached)
We are also upgrading from Oracle to MSSQL
Tried the search for any solution, but was not successful; any suggestions were for 7.2 or no answer. Can you please help me to resolve this issue?
