Sale Order Inconsistancy

Question

Dear All,
I have an scenario, I am going to assign the serial numbers in Delivery of the sale order only, and not in
Production Order.
I Created the serial Number, in IQ01-as 'S' , and assigned at the time of PGI in sale Order.
When there is a customer return and i created the sale order with diffrent order type (return) using the reference of billing document number of earlier sale order for which i did PG/Billing.
But At the Time of of doing PGR for this order i am giving the same serial number which i gave earlier, since the Item and customer is same, But system is showing the error/Warning 'System status ECUS is active (EQU 10000338)'
Read as:
     {  System status ECUS is active (EQU 10000338)
Message no. BS011
Diagnosis
System status ECUS (At customer site) is active for object EQU 10000338. When this status is active, the system issues a warning before executing transaction 'Delivery note assignment' }
Now If change the system status to Forbidden and made it to error it works fine in case of avoiding the same serial number being sent to diffrent customer for same mat code.
This perticular message shall behave diffrently,
1) When I do PGI it should not allow the PGI with the same serial number or the used one.
2) When I do Customer return and do PGR it should allow since the same number i am going to take back.
The Serialization procedures used are: OIS2
SDCC     Completness check for delivery     03     02
SDCR     Completion check IR delivery     02     02
SDLS     Maintain delivery     02     02
SDRE     Maintain returns delivery     02     02
Please help me out guys..

Hello Raghu
When you assign the serial number at the time of PGI system created a master record for serial and material number ( if in your system automatioc creation of equipment if defined it will create so in the background).The system sets the status of equipment as "AT CUSTOMER LOCATION"
I remember I had this issue once but one simple way is to go in the transaction IQ02 and change the status to some other options I dont remember now...This will allow you to PGR with same serial number.
