Duplicate BDOC's generated in CRM during IBASE save

Hi,

Once we edit an IBASE ( even just description) and save it we find that duplicate BDOCS are generated of type 'CRM_IBASE_MESS'. The data in both the BDOC is same. When we debugged the Function module 'IB_CRM_BDOC_FILL' is used to populate the BDOC. But even this FM is hit only once so we are not sure where the other duplicate BDOC is created from.

Also this behavior is noticed in our test, production but not in Development system.

Can someone please help.

Thanks in advance,

Arvind Raj.
