segment Type

Former Member — Thu, 21 Dec 2006 06:09:23 GMT

Hi all,

A data extract consists of sequence of data segments. Data segments are characterized by segment type and segment Data.

The following segment types are available:

01 file Header

02 Segment directory

03 Meta data

04 Selection criteria

05 Data Records (transaction and master data)

06 Checksum records

07 Customizing Data.

But I am not getting what is Segment-Type here?

what do you mean by Checksum records ?

Help me out

Thanks in advance

hi,

A data segment contains a collection of fields from SAP tables. A data segment may hold master data or data from an application document. A segment is a collection of all the records of one type. A segment may contain data from a single SAP database table, or it may combine related data from multiple tables.

A checksum is basically a one-way hash of whatever data arguments you supply.

Basically in your context the data is classified into different areas(i.e. segments). Example that the file header information namely the name, number of records, create date etc would form the data with type 01 similarly for the others.

As for checksum, whenever some data is transmitted you perform some checks at the end to verify if the data received is correct.
