Error Messages

ORA-01440: column to be modified must be empty to decrease precision or scale

Steps to Reproduce

1. Install and Configure PegaSurvey 7.1 and Healthcare Industry Foundation 7.12 as per the documentation.
2. Import HCIF Sample Data to verify the HCIF installation.
3. Install CMF 7.12.

Root Cause

In out-of-the-box Pega 7.1.7, define the column, PR4_RULE.pyaccessibilityLevel as number data type. In Oracle, the number datatype precision can range from 1 to 38 and scale can range from -84 to 127. However, the migration script, AB_CMF_712_for_Pega_71.jar\CMF_7_12_22_jan_schema.jar\pegarules...pr4_rule.xml indicates to change the precision to 10 <column dbtypename="INTEGER" name="pyAccessibilityLevel" size="10" type="INTEGER"/>.


1. Import AB_CMF_712_for_Pega_71 referring CMF upgrade guide.
2. When asked to apply schema changes, it gives checkbox to apply schema changes manually or automatic. Choose the Manual option
3. Download the SQL. Remove following ALTER statements and Execute.

        ALTER TABLE ENG_TE_2727_RULES.pr4_rule MODIFY pyAccessibilityLevel NUMBER (10, 0);
        ALTER TABLE ENG_TE_2727_RULES.pr4_rule MODIFY pyBrowserSupportLevel NUMBER (10, 0);
