I would like to group by one field and sort by another field with Crystal Report.

For example: `Group A` with `PO Number` (sort ASC). For each PO Number, there is one Name with it and I would like to sort by `Name_x`.

I have tried to add a field with `Record sort Expert` or I created a new group with `Name_x` and then sort by a new one but it does not work.

```
PO_1         Name_4
PO_2         Name_2
PO_3         Name_3
PO_4         Name_1
PO_5         Name_7
PO_6         Name_6

```

**The result must be:**

```
Name_1       PO_4
Name_2       PO_1
Name_3       PO_1
Name_4       PO_1
Name_6       PO_6
Name_7       PO_5

```
