Variable and input parameter error

Hi All,

I am getting below error when clicking value help in varible screen of Calculation View.

SAP DBTech JDBC: [2048]: column store error:search table error: [6968] Evaluator: system error in expression string; expected TK_ID,parsing

'in("MATNR",[here])'

I have selected value help from current view column.

Variable is on a calculated column "YEAR" which is derived from "DATE".

I want to know why is this not showing the list of year values in the view. Same case when i use value help as current view in input parameter of MATNR. Please help me in solving this issue.

Thanks,

Rithika
