E28024 Syntax error in simple action/procedure (Line 1)

Hi All,

I have created function module and function for the dependency as per the data given in below link

https://help.sap.com/viewer/61155ee7ed304ae8b66b7526555a6a07/6.17.17/en-US/dd63b6531de6b64ce10000000a174cb4.html

I have created a class and assigned 3 characteristic Zgrade, Zseries and zvariants1.

Created the configuration profile and while assigning the dependency i am getting the error E28024 Syntax error in simple action/procedure (Line 1)

i have written the following code in dependency

FUNCTION ZVARIANT1

(ZSERIES = $ROOT.ZSERIES,

ZGRADE = $ROOT.ZGRADE,

ZVARIANTS1 = $SELF.ZVARIANTS1)

Functions and FM have been created correctly.

Could any one help here. I am new to VC.

Thanks and Regards,
