It seems that you are having problems with transaction structure and its form (screen layout).

About SPC0052 error

Attribute CityId seems to be part of the transaction key. I assume you have a structure similar to:

CountryId*
CountryName
      (CityId*
       CityName)

Every key attribute (CountryId and CityId in this example) must be present on the screen or assigned in the transaction rule. Otherwise, how will it have a value? (remember that Key attributes cannot be “null”)

About SPC0104 error

It seems that you defined a grid for the first level (countryId) and this is not allowed. For the above sample structure, the form should be “plain” for the first level and “grid” for the second level

How to fix them? It depends on the structure and form that you have defined. Perhaps the easiest way is to apply default form (positioned at transaction form, option edit/Apply Default (Web Layout)
