Problem with Foreign Key relationships in SAP R/3 4.7

Posted on Aug 13, 2009 at 12:05 AM 14 Views

Hi Experts,

I am trying to create a foreign key relationship between 2 transparent tables in SAP R/3 4.7

Table 1:ZAAVNDR (MANDT (pk), VENDORNO (pk), NAME, REGION, COUNTRY (fk)) Foreign Key Table

Table 2: ZAAVNDRREF(MANDT(pk), COUNTRY (pk)) ---Check table

I have added few valid countries in check table but when I am adding some records in foreign key table with invalid countries these records are not being restricted and are still successfully going into the table.

Could any one please help in this.

Thanks in anticipation.

-Amit

    In both the table COUNTRY field should be Primary Key.

    In your case , in table ZAAVNDR , it is not.

    Make COUNTRY as primary key in ZAAVNDR table.

    It will work as your requirment.

    While defining the foreign key relationship please check to see if the 'Check Required' flag in the 'Screen Check' section has been selected.

    How are you adding entries to the table? If you are doing it through a program via an INSERT statement, then the check is not performed. You will have to do that in your program.

      Hi,

      I am adding records by using the Menu (Utilities->Table Contents->Create Entries). Even after making Country PK in both the tables still the records are not being restricted.

      Could you please help.

      Thanks

    Hi,

    Please go through following points, I hope it will helpful for you.

    1. Maintain primary key in field 'COUNTRY' in both the tables (foreign key table & check table). Note: both fileds should have same data element.

    2. Maintain foreign key relation for field 'COUNTRY' in foreign key table.

    3. Since table is changed so you need to "Activate and Adjust Table" using transaction SE14

    Regards,

    Moqeeth

    From the previous replies I think that maintaining the foreign key relationship for country code via SE11 in the vendor table is essential, however the primary key should remain unchanged. I mean, how can you recommend changing the primary key to country code in a table with data related to vendors?

    Check

    1. The domain of the COUNTRY field in both the table are same.

    2. The Foreignkey relationship is created properly .

    3. all the table and components are active.
