Code generation for business partner

Question

Hi, all
In our scenario we need to assign a unique code to business partner record as soon as it is approved by data manager (in MDM workdlow). This assignment should be automatic. Next incremental number would suffice, but AutoID field can't be used for this purpose since it automatically assigns numbers even to new, still not approved records.
Some kind of this pseudocode in assignment would be great:
CODE = MAX(CODE)+1
Where MAX(FIELD) is a function returning maximal value in FIELD field in current table.
But I couldn't find such function in data manager standard functions list.
Can anyone suggest a solution?

hi thanks for your valuable replies...
i changed the codes...pls check its right or wrong
declare @temp as char(20)
IF $[OCRD.GroupCode] = 104  and $[OCRD.cardtype] = 'c'
BEGIN
set @temp=(select isnull(max(right(cardCode,7)),0) + 1 from Ocrd where (groupcode= 104) and (len(cardCode)=7))
set @temp='TRA'isnull(replicate(0,7-len(@temp)),'')@temp
select cast(@temp as char(20))
END
ELSE IF $[OCRD.cardtype] = 'C'
BEGIN
set @temp=(select isnull(max(right(cardCode,7)),0) + 1 from Ocrd where   (len(cardCode)=7))
set @temp='C'isnull(replicate(0,7-len(@temp)),'')@temp
select cast(@temp as char(20))
END
ELSE IF $[OCRD.cardtype] = 'S'
BEGIN
set @temp=(select isnull(max(right(cardCode,7)),0) + 1 from Ocrd where   (len(cardCode)=7))
set @temp='S'isnull(replicate(0,7-len(@temp)),'')@temp
select cast(@temp as char(20))
END
