Hi Akhilesh,
I think SAP suggested to use the bol query ProdAdvancedSearchProducts or the dynamic bol ProdAdvSearchRgProducts( I would try the first one ) because I don't see a direct relationship or method in the Bol entity ERPAdminI. Will be interesting if you copy paste the SAP response because I don't really get why is better to use bol query instead of the API.
BTW did you try COM_PRODUCT_GUID_GET with the import parameter IV_UPDATE_BUFFER set to X?
Cheers!
Luis
