Table for project version - external services.

Hi Experts,

I am looking for a table which can provide the external service item detail with reference to project version. I am able to get for the material using VSRESB_CN which provide me the material information for a particular version key.

I am using the table VSAFVC_CN to get the PACKNO for the service detail. However , when I use the sub-packno in ESLL the service items are not specific to particular  version key  since this table is showing the real time value of the service items define in the project.

Thanks in advance.

Regards

DP
