is it possible to fetch matrix column through formatted search in UDF?

HI,

Is it possible to fetch the value of first row of quantity column in user defined field through formatted search?

SELECT $[$38.11.number]

does work but in user defined column of matrix only. I have requirement that when there will be only one row in matrix, the quantity should be accessible in user defined field. and for this, the above query gives internal error.

thanks and regards,

Binita
