Hello,
I found the following:
If you fill someting in the fields REFOBJ_IBASE, this value is being converted into a GUID internally
This happens in function CRM_BSP_OIC_1O_SEARCH_FROM_RF
So you have to make sure that the search field REFOBJ_IBASE points towards the field CRMD_SRV_REFOBJ~GUID_OBJECT ( via table CRMC_REPDY )
And even then I have the impression it only works when you only fill the Ibase in the order. When you fill the component there is a different GUID.
In my case I found out it is even more complex, so I will need to create my own search field (extend search structure )
Regards,
Erwin
