Error - Create chemical using program

Hi All,

I am trying to create a chemical using BO EHFND_CHEMICAL using program. Referring the sample code listed in 'Navigating to BOPF' blog series.

I have passed ROOT node and BI_CHEMICAL nodes. But I am getting error 'Mandatory node ROLE is missing'.

When I tried to add ROLE node , in the code its giving errors like 'Mandatory node ROLE is missing' OR can not create, source object does not exist'.

I went through the node structure for the BO. In it we have Root - > Revision -> Role.

So my query is how to pass information for ROLE node? We need to add REVISION node also?

If anybody can guide, will be really helpful.
