How to fix this error?

INCLUDE NA_SYSTEMVERWALTUNG
IF &[SWITCH]S4H_DOCU_ON_PREMISE& = 'X'.

Procedure for System Administrators

The posting string reference of the movement type (field
<DS:DE.BUSTR>BUSTR</> of <ZH>Table T156: Movement Types</>) does not
correspond with any standard posting string reference.
Case A:
The entered movement type is a copy of a standard movement type. The
affected movement type was not modified. However, the movement type was
changed in the standard after copying. In the sequence, a customer-
defined posting string reference was created in the upgrade to SAP R/3
4.6A or higher.
In this case, delete the movement type and copy the movement type again.
The system automatically determines a standard posting string reference.
Case B:
The entered movement type was modified, and the customer-defined posting
string reference is to be held. Enhance your modification by including
the missing entry in the table <ZH>MIGO_T156: Movement types - Reference
MIGO</> with the help of transaction
<DS:TRAN.SE16>SE16</>.
ENDIF.
