EDI: Syntax error in IDoc (segment cannot be identified)

Hi,

I am getting below error in IDOC, Please suggest what could be the possible reason for this.

EDI: Syntax error in IDoc (segment cannot be identified)

Message no. E0078

Diagnosis

The segment E1EDP02 does not occur at the current level of the basic type ORDERS05 (extension ).

This error can have several reasons:

• The segment E1EDP02 is assigned to a group whose header segment does not occur.

• The segment E1EDP02 does not exist in the syntax description of the basic type ORDERS05 (extension ).

• The sequence of segments in the group in which the segment appears is incorrect.

Previous errors ('mandatory' segment or group missing) may be due to this error.

Regards

Ankesh
