AD_ZD_TABLE : Steps to follow while creating table in R12.2.*

Image
  *********** * GRANTS * ********** Team – do not use Grant statements in the SQL scripts while migrating through STAT , instead use  EXEC AD_ZD.GRANT_PRIVS. Manual steps run in DEV Environment: 1. As XXCUST, manually Create/Alter custom table in EBSDEV or EBSPROJ (XXCUST schema for all custom tables). 2. In EBSDEV/EBSPROJ: If creating the table, run:  AD_ZD_TABLE.UPGRADE (‘SCHEMA’,’TABLE’); If altering the table, run: AD_ZD_TABLE.PATCH (‘SCHEMA’,’TABLE’); 3. Insert at least one row of data in the custom table. * This is mandatory for XDF to extract the table definition and for successful Stat archive set creation. 4. As table owner, grant privileges on new/altered table and editioned view to APPS, primarily so AD_ZD.GRANT_PRIVS can be run for privileges. GRANT ALL ON SCHEMA.TABLE TO APPS WITH GRANT OPTION; GRANT ALL ON SCHEMA.EDITIONED_VIEW# TO APPS WITH GRANT OPTION; 5. If additional privileges are required on the new/altered table, the following needs to be r...
