SYSFAIL Error in SMQ2 - Transfer of material from R/3 to CRM

Hi,

We are using standard BDOC to transfer material from R/3 to CRM. BDOC Type is PRODUCT_MAT, Queue name is R3AD_MATERIA<Material No>.

There are some queues which are struck in SMQ2. There are no struck queues in R/3. The struck queue has the status SYSFAIL and when I double click, it shows Message - Error in Mapping (Details: transaction SMW01)

I checked transaction - SMW01. The queue name which is in SYSFAIL status is not coming up in SMW01.

I do not understand whereelse I can see the detailed error message.

This error does not occur for all articles.

As I don't have sufficient knowledge in CRM and BDOCs, any pointers regarding the issue will be very much helpful.

Thanks and Regards,

Lakshmi
