Getting an error "Customer could not be determined" for IDOCs in SCM 7.0

Question

Hi Friends,
    I am executing the report RSMIPROACT in ECC 6.0 system to publish Demand and Stocks into the SCM 7.0 system.
The IDOC is processed without any errors in ECC 6.0 . However, in the SCM 7.0 system , the IDOC fails with the error.
I have noticed that 2 things .
1.  E1ADRE1 field is NOT being sent by the ECC system .
2. I get the same error even if I manually add this field and add value 300 or 301 for the qualifier field.
Has anybody faced this problem before ?
I look forward to replies.
Detailed error is given below.
Regards,
Ranjini.
Customer could not be determined
Message no. /SAPAPO/EDI010
Diagnosis
The system must determine the customer number from the IDoc data in order to update stock and sales figures for customers. It uses the additional section E1ADRE1 with the qualifier '300' or '301' in the vendor address section to do this. The customer number stored here should have a valid customer number in the APO System.
The section was not available in the processed IDoc.
System Response
The system cancels processing.
Procedure
Configure the EDI convertor in such a way that the corresponding section has a value.

Answer 1

Hi Ranjini,
Please look into the following
1) Customer master data is fully maintained
2) Customer number ranges are fully defined in customisation
3) Customer address details are maintained
4) Is there any special characters used while defining customer data or customer
number like $, #,[ etc.,?
5) Customer int models are active in SCM side prior to IDOC processing (including
customer, demand, stocks etc)
Please confirm your findings
