Unable to create code combination using API "FND_FLEX_KEYVAL.VALIDATE_SEGS"

Hi Team,

I am unable to create code combination using API "FND_FLEX_KEYVAL.VALIDATE_SEGS".

Dynamic Inserts have been enabled and Cross Validation Rules have not been enabled.

Below is the code snippet.

        lb_status := fnd_flex_keyval.validate_segs(
                                                   operation        => 'CREATE_COMBINATION',
                                                   appl_short_name  => p_application_short_name,
                                                   key_flex_code    => p_key_flex_code,
                                                   structure_number => p_structure_number,
                                                   concat_segments  => lc_concat_segs);

lb_status is a BOOLEAN variable.

Is there any setup required?

Please guide me on the same.

Thank you.

Regards,

Krishna
