Multiple customers in Sender Party for IDOC type KU

Hi All,

My scenario is IDOC to HTTP with sender IDOC Type KU.

We are using PO 7.4 and IDOC_AAE.

I have done the following settings.

Created a Sender Party and assigned a customer under party identifiers. (Also I can't add multiple values with same Agency and scheme it throws eror in PI)

For a single customer the end to end scenario is working fine.

But if I try to send the IDOC with other customer Number it fails as the entry is not maintained for that customer in Sender Party identifiers.

Also I can't afford to create a different party for each customer as there are hundreds of customers in the ECC Application system.

I also tried with value mapping but it won't worked.

Please suggest on this.

Regards,

Nitin...
