Post goods issue VL02N

Hello all,

I have a situation that i dont understand.

Imagine that i have an outbound delivery with an item wich material should contain serials. This delivery is to be transferred to another center.

If i make the PGI - post goods issue - using the normal way, transaction VL02N, it will generate a material document with the serials inside the document. that's right and what we want.

But, if i code a BDC or create an LSMW the serials did not appear in the material document.

Did someone face the same issue?

Kind regards,

Pedro Nunes.
