How to change Preferred Vendor to Fixed Vendor in SC - SRM-5.0

Question

SRM Experts,
We are using SRM 5.0, ECC 6.0 and PI-7.0.
We are using classic scenario in SRM. When user selects the vendor with Outline agreement in SOS tab then SC creates PO in backend system because it has Fixed Vendor otherwise SC creates PR in the backend system.
We have a new requirement in SRM to create PO instead of PR in the backend system if Purchasing Org=5xxx and total value of SC is less than USD 5XXX and Vendor is a Preferred Vendor in the SC.
Do I need to use the Check Document BADI to check the total value of the SC and to check whether it is a Preferred Vendor and then in the Change Document BADI, change the value from Preferred Vendor to the Fixed Vendor before SC is saved?
OR someone has any other suggestions on this?
Which BADI is called first Check Document or Change Document before saving the SC?
Thanks in advance!

Hi Atul/Disha,
I sent you my code and problem in detail at your email address.
Here is the requirement for Changing Preferred Vendor to Fixed Vendor. We are on SRM 5.0 and using classic scenario. I am new to SRM world. I also checked the note- 962474 in our system and it has been applied. We upgraded to SRM 5.0 in Oct-07.
1.     My client has customization for sources of supply tab. It shows the vendor information in SOS tab based Product category, Plant and Purchasing group selected in the SC. If SC contains Vendor with Outline agreement then SC creates PO in the backend system. So in Change BADI logic for new enhancement of converting Preferred vendor into Fixed Vendor should not change anything in the SC using Outline agreement.
2.     We have created Custom table-zsrm_fix_vend with fields, purchasing group, company code, currency and total value.
3.     We need to convert the preferred vendor into fixed vendor
    if the SC’s 1st line item purchasing group = zsrm_fix_vend-ekorg and
             SC’s 1st line item company code = zsrm_fix_vend-bukrs     and
           SC’s currency = zsrm_fix_vend-currency                   and
           SC’s Total value less than(<)zsrm_fix_vend-totalvalue.
My testing results and problems…
1.     When I create a new SC with less value than totalValue from the custom table, change document BADI is changing the preferred vendor into fixed vendor and it is creating PO in the backend system. So this is working as expected.
2.     When I create a new SC with greater value than totalValue from the custom table, change document BADI is NOT changing the preferred vendor into fixed vendor and it is creating PR in the backend system. So this is working as expected.
3.     When I use Outline agreement in the SC, it is creating PO in the backend so change BADI logic is not affecting this existing functionality which is good.
4.     Problem - When I copy a new SC from existing SC with less value than totalValue from the custom table and then changing the amount with the greater value than the custom table, change document BADI is not changing the fixed vendor to the preferred vendor and when I click on sources of supply tab - it is giving me an error “Partner Function may not be Changed” and it exits me to main shopping cart screen.
5.     Problem - When I copy a new SC from existing SC with greater value than totalValue from the custom table and then changing the amount with the lessser value than the custom table, change document BADI is not changing the preferred vendor to the fixed vendor and when I click on sources of supply tab - it is giving me an error “Partner Function may not be Changed” and it exits me to main shopping cart screen.
6.     When I copy the SC with Outline Agreement and change the amount it works all the time it is not affected by the change document BADI which is good.
Please help me to resolve this issue.
Millions thanks to you!
