POI IDocs 
This table provides an overview of the type of data that can be transferred from the SAP system to external systems for optimization and the corresponding message types.

In this document contains tables illustrating each of the POI IDocs and their segments. Each table represents an IDoc segment and contains a list of fields, a short description of each field, and the field lengths.
The data types listed here correspond to the data types each segment has in the SAP system.
In POI, data is transmitted in CHAR format. SAP offers conversion options (for example, to ISO codes) with adjustment possibilities for input fields in CHAR format. The following data types are among those that are converted:
units of measurement (ISO code)
currency code (ISO code)
country code (ISO code)
shipping instructions (ISO code)
currency entry (mandatory conversion)
dates and time specifications
Because of these conversion factors and depending on the data type, there are differences in the internal and external field lengths.
To convert units of measurement, in Customizing, follow Global Settings ® Check units of measurement.
In this customizing step you can enter a corresponding ISO unit for every SAP one. If you don‘t enter an ISO unit, the SAP code is transferred in the IDoc. Important: Only the unit itself is converted, not the corresponding quantities, amounts, times, etc. There must be a 1:1 relationship between the ISO and SAP codes if you enter an ISO unit.
During the POI upload the ISO unit is automatically converted. Transferring SAP units can cause error messages in the POI upload log. If you do transfer unconverted SAP units, use the prefix SAP_CODE (upper case characters) in front of your unit. For example, use SAP_CODEKG for SAP unit KG.
For further information on conversion codes, see Cross Applications → ALE → Consultant’s Handbook or Programming in the SAP Librar y.
For specific information on the internal and external lengths of IDocs, follow the path Tools → Business Framework → ALE Development. In the ALE development screen, follow IDoc → IDoc basis → Documentation → IDoc types
In the documentation as well as in the SAP dictionary, all segments have the prefix E1 (for example, E1MAPL). As soon as the segments are transmitted via ALE, the prefix changes to E2. For instance, if you send segment E1MAPL in an IDoc to an external system, it will arrive labeled E2MAPL.
The different versions of a segment are identified by the number following the segment name (for example, E1CRHOL001). New versions are created whenever fields are added to a segment.
