Set AUFNR in LIPS by user exit

[jens_feldkamp1]

Dear gurus,

we do cross-company stock transfers. After we created a STO, a delivery of type NLCC is created automatically.

Now, we would like to set the field AUFNR in the delivery items.

I tried using USEREXIT_MOVE_FIELD_TO_LIPS in MV50AFZ1, but the value set by my coding is almost immediately overwritten from structure xkomdlgn by standard coding.

Any ideas?

Thanks
Jens
