assign incremental number to children(member)

[orbair]

Hi All,

I am facing a problem when I have a crosstab, where the rows are caption(children(member)). The client wants to make them numbered (in this case put a letter before them).It looks this way.

A child1
B child2
C child3

Any idea how can I do this? I am using TM1 cube, DQM.

Thanks in advance.
