Problem with Idoc segment maximum length

Hi friends,

We are now creating a new Idoc type. We have started to create the first segment but we encountered a major problem.

The problem is that we have a field of 4000 characters but the limit of all segment fields together is 1000 characters.

Is there any way to change this limitation or another way to define Idoc?

Thanks in advanced,

Udi Dekel.

When you create a segment that exceeds the max length, SAP automatically creates a child segment for the exceeded length. For your problem though, you can create 4 segments of length 1000 each and split the data in these 4 segments and then concatenate the data later in the idoc processing function module. On the other hand if it is an outbound idoc, you can ask the receiving system to do the same.

Best regards,
