E28112 Error in table/function argument in AVC

Hello Team,

I am working in S4HANA 2020 AVC where I have created a VC Model. I have used AVC mode for both Dependency Net and Constraint. The Variant Tables are setup and its contents are correct without any inconsistencies. But when I do a syntax check on the constraint where this Variant Table is used, I get the error 'E28112 Error in table/function argument ....'.

The same syntax works fine in 'Classic' mode but not in 'AVC'

Appreciate your valuable inputs.

Thanks
