Set variable for use in different make target

I have a make target that calls another, I want to set the variables in the make target that calls the target it depends on and pass the variables down.

FILENAME ?=
SERVICE ?=

generate-transaction-command: generate-service
   FILENAME := swagger.json
   SERVICE := transaction
    
    
generate-service:
   @curl -s http://localhost:8181/swagger/proto/$(FILENAME) --output ./$(FILENAME)
   @./gen -input ./$(FILENAME) -output ./cli/cmd/$(SERVICE).go

I want to be able to run make generate-transaction-command and then my generate-service command uses the variables set in the generate-transaction-command, at the moment it gives me this error.

FILENAME: No such file or directory

So I assume it isn't setting the variables correctly.

See Target-specific Variable Values
Example:

FILENAME ?=
SERVICE ?=

generate-transaction-command: generate-service
    @echo $@ recipe

# set variables for a target:
generate-transaction-command: FILENAME := swagger.json
generate-transaction-command: SERVICE := transaction

# added echo
generate-service:
    @echo curl -s http://localhost:8181/swagger/proto/$(FILENAME) --output ./$(FILENAME)
    @echo ./gen -input ./$(FILENAME) -output ./cli/cmd/$(SERVICE).go

output:

curl -s http://localhost:8181/swagger/proto/swagger.json --output ./swagger.json
./gen -input ./swagger.json -output ./cli/cmd/transaction.go
generate-transaction-command recipe
