Create TO item using enhancemant MWMTO003

Hello,

I use enhacement MWMTO003 (Own stock placement strategy) to find an empty sorage bin. Now, I have problems when there are several TO items for one TR item. In the enhacement I select an empty storage bin (kzler = 'X') from lagp. When creating the second TO item, I select the same storage bin again. Because there was no update on lagp. I can remember, that there is a function module, that lists already created TO items but not recorded yet.

Can anyone tell me the name of this function module?

Thanks!!!

Rgds
