Problem during hierarchy load from ECC 6.0 to BW

Hello,

I encountered a problem during hierarchy loads from ECC to BW:

I get the following in BW:

Error when updating Idocs in Source System

Diagnosis

Errors have been reported in Source System during IDoc update:

Once I go into ERP and look at the IDocs I get the following message:

Idoc Error 26:

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

Message no. E0078

Diagnosis

The segment E1RSSH does not occur at the current level of the basic type (extension ).

This error can have several reasons:

The segment E1RSSH is assigned to a group whose header segment does not occur.

The segment E1RSSH does not exist in the syntax description of the basic type (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.

Procedure

Please check the IDoc or the syntax description of the basic type (extension ).

Can anyone help?
