Bind one context node to another node.

Hi

I have a requirement that need to fetch the 'SLA' context node values to the context node 'BTSRVREQUESTH 'of the same view 'AIC_INCIDENT_H/IncidentHeaderEF' from the component  'AIC_INCIDENT_H'.

I know by using custom controller binding we can fetch the values.

Problem is that SLA context node is Value node, how to know from which table, the attributes are taken in to SLA context node and how to create a custom controller context node of same type as SLA.

Finally, suggest me how to create a custom controller context node same as SLA context node and let me know is any other approach to fetch the values.

Component: AIC_INCIDENT_H

View: AIC_INCIDENT_H/IncidentHeaderEF

Context nodes: SLA

                       BTSRVREQUESTH

Regards,

Manoj
