BADI MB_DOCUMENT_BADI dump error

Question

Hi all,
am using BADI : MB_DOCUMENT_BADI,method MB_DOCUMENT_BEFORE_UPDATE,to have checks in MB1A(Goods Issue transaction).I have written a code to check some values,after checking and raising an error message if I press enter the following dump error is coming:
Error analysis
    Short text of error message:
    Internal error: Multiple call of update function module
    Long text of error message:
     Diagnosis
         In the FORM routine Buchen_Ausfuehren (program SAPMM07M), an error
         message was issued by a Business Add-In (BAdI) or function module.
         This is not permitted, because it could lead to data
         inconsistencies. For this reason, the update of the material
         document was also terminated with a termination message (dump).
         Note that this message (M7 372) is not the responsible error
         message.
     System Response
     Procedure
         Contact your system administrator.
     Procedure for System Administration
         If there is an active implementation of the Business Add-In
         MB_DOCUMENT_BADI, check that no error message is issued in the
         MB_DOCUMENT_BEFORE_UPDATE method.
    Technical information about the message:
    Message class....... "M7"
    Number.............. 372
    Variable 1.......... " "
    Variable 2.......... " "
    Variable 3.......... " "
    Variable 4.......... " "

Hi,
This BADI is called in update task.
So as a result when you call your error message, SAP is retuning it as message type 'X" and an update termination occurs.
I was facing a similar problem becuase i was trying to update measurment doc via this badi.
Incase the measuring document was locked by some user my FM used to throw an error message and that would lead to a message type 'X' in this badi.
So if you want to do some validations only; please use the following BADI.
MB_MIGO_ITEM_BADI in the method ITEM_MODIFY.
