Hi Anothai,
>> my question is that where the value of units come from since i 've never inputted it in the security id.
[Renatas]: as I mentioned, in FWZZ it is purely Notional number to verify pricing of relevant Security class. and of course, when you enter Master data of Security class, you don't specify actual number of unit/ volume of Securities bought/ sold - this is done in FTR_CREATE. and yes, the value (of 1,000) is fixed.
Kind regards,
Renatas
