Optional Input Parameter with multiple values
We defined Optional input parameter with multiple values for a material in graphical calculation view
If we don't select any material in the filter then it should return all the materials or it should get only the materials if we enter the material in the filter.
for this in the filter expression we are using the below syntax
in("MATNR",'$$IP_MATNR$$') or match ("MATNR",'*$$IP_MATNR$$*') .
With this expression we are getting syntax error.
Can any one help how to write filter expression for this requirement.
