Thanks Ravi, for your sugestion.
However my requirement is to load all the Open POs from SRM 5.5 to SRM 7 system.
We are not upgrading from SRM 5.5 to SRM 7; its a new implementation of SRM 7.
I was looking for SAP standard solution for this however looks like there is no such standard solution and i will have to design my own solution.
I am planning to use BAPI_POEC_CREATE to create a PO in SRM 7.0 Extended classic system.
I will validate requisitioner, Goods recipient, location, company, vendor from SRM tables.
Apart from this do you have any other suggestion on validations?
Regards,
Ashish
