Adding Process Logic to a Dialog › Adding Process Modules to Dialogs Using ADSC › Correct structural errors

Correct structural errors

At compile time, errors in a process module can arise because of discrepancies between the process module and other dialog components. These are called structural errors.

For example, you may have added the wrong subschema to the dialog. In this case, error messages are returned for process commands that reference records that exist in the correct subschema but don't exist in the specified subschema.

To correct discrepancies caused by other dialog components, you display the ADSC screen that associates the component with the dialog:

• For a map, display the Map Specifications screen.
• For a subschema, display the Database Specifications screen.
• For a work record, display the Records and Tables screen.

  Dialog XXXDADD doesn't contain a work record, so you don't need to check for work-record errors in the dialog.

Checking the Subschema Definition

For example, you check the subschema definition for dialog XXXDADD by displaying the Database Specifications screen:

                             Database Specifications

                         Dialog  XXXDADD   Version     1



   Subschema . . . . . . . . . . . .   EMPSS01
   Schema  . . . . . . . . . . . . .   EMPSCHM
   Version . . . . . . . . . . . . .      1

   Access Module . . . . . . . . . .   XXXDADD

   SQL Compliance  . . . . . . . . .   _ ANSI-standard SQL

   Date Default Format . . . . . . .   _ 1. ISO
   Time Default Format . . . . . . .   _ 2. USA
                                         3. EUR
                                         4. JIS





 Enter  F1=Help  F3=Exit  F4=Prev  F5=Next

When checking a component specification, you need to verify that both the correct name and version number are specified.

For example, dialog XXXDADD uses subschema EMPSS01. This subschema is defined in version 1 of schema EMPSCHM. Some sites define different copies of schema EMPSCHM. In this case, you check the Database Specifications screen:

• Expected specification:

     SUBSCHEMA.: EMPSS01      SCHEMA: EMPSCHM    VERSION:    1
  

• Incorrect specification:

     SUBSCHEMA.: EMPSS01      SCHEMA: EMPSCHM    VERSION:    2
  

To correct any specifications, type the correct information over the previous specification. When dialog components are all specified correctly, you can proceed to correct any syntax errors in the process module.
