Goods Issue through IDOC

Hello All,

We have the situation as follows:

1. A sales order is created.

2. An outbound delivery is created automatic through worklist.

3. An IDOC DELVRY03 is generated through message determination. The IDOC is sent through EDI to 3PL.

4. 3PL picks the material and confirms the picking result by IDOC.

My question is: Which message typ and IDOC type can I use for carrrying out goods issue?

Thank you in advance!
