Hello Andrew

An APPEND structure is a DDIC structure that is assigned to a single DB table. In the ABAP dictionary (SE11) you call the corresponding DB table and create the APPEND structure for this table.

In which scenario do we create APPEND structures? Obviously, the attributes available in the DB table are not sufficient to meet your requirements. Thus, you append the missing fields to the table.

What is the difference between an APPEND structure and a "normal" structure? An APPEND structure is assigned to a single table whereas structures could be included in many tables.

An important point to consider when enhancing a table is the so-called "enhancement category" of the table (menu Extras -> Enhancement category). This table property will become particularly important in an unicode environment. For details see the SAP documentation about

I am using it with EXIT_SAPLV50Q_001, to generate a report from standard VL06F with the additional shipment fields I am going to add in it.

Thanks Uwe

Hello Andrew

I guess my first answer did not hit your point exactly. Based on the exit I assume your target is the LIPOVZ include in structure LIPOV. For one of our customers I had to enhance a similar include. I do not remember if I had to modify this SAP structure or not, but in any case I had to remove the DUMMY field and add the required fields.

Based on the exit's interface I would guess that is the place where to fill/modify the additional fields with data.

Thanks for your reply. Honestly, its the first time I am working on something like this and I have no where abouts of how to write a specification document for this. The one I wrote before, I was told there were performance issues associated with that report so this is my only other option.
