Public bidding scenario?
Dear Experts,
There is a business scenario where the client requires fresh bidders for his bid invitation? He does not want to engage existing bidders present in SRM system? He does not have any ROS (registration of Supplier) system for registration of fresh suppliers/bidders?
He does not want to use OPI to access third party supplier directory to invite fresh bidders.
Could you please comment on how to achieve further with the given constraints?
Your feedback is highly appreciated.
Thanks and regards,
Ranjan
Dear Experts,
How we can invite fresh bidder for a public bid invitation? Say, the client does not have any ROS system or has not configured OPI.
Can we in such cases use the supplier self registration in SRM system like user registration? Since Bidders have anyway to be created in SRM system, could we visualize a scenario as below?
1. The bid is published.
2. The interested parties visit the buyer's website and see the public bid.
3. Request for registration.
4. Workflow (standard if available, or custom developed) is activated.
5. A task does appear for the approval of the bidder in the purchaser inbox.
6. The purchaser approves the bidders.
7. The bidder is created and notified via e-mail informing the access data.
8. The bidders now submits the bid against the public bid.
Can we design such a process?
Thanks and regards,
Ranjan

Classic Scenario: follow on document from BID
Dear All,
We are trying to create a PO from an accepted BID . We can create the PO, and if we check it in the backend system, everything is OK.
Our problem is that we are trying to find in SRM, somewhere that shows us the follow on document of the Bid but we can´t find it.
It´s important to say that as soon as the PO is created, we get a message that contains the PO number. But after that, we can´t find in SRM the PO number anymore.
Is this a lack of SRM or may be another problem? Has anyone face up with this issue? If so, How it was resolved?
Thanks,
Pablo.-I noticed that you have a very similiar Bidding scenario that we have. We can create a bid invitation in SRM and we have used the BADI - BBP_DETERMINE_LOGSYS to indicate to the system to create a purchase order in the backend system after the bid is accepted. We keep getting the following error in SM21: Purchase orders cannot be created without IPC pricing
Did you have to turn on the IPC in order to create the purchase order in R/3? We are on SRM 4.0. Also, if you have used the BBP_DETEMINE_LOGSYS Badi and have example code that might be helpful as well...thanks! -
SRM Public Sector Tendering Process
Hi Experts
Have a question.
In SRM 7 Public Sector Procurement (PPS) scenario, I publish the bid against which the bidders provide with their Technical Response. I publish the bid as 'Public Bid'.
Question 1: How will the bidders log in to the portal to submit their bids? Would it be with a common ID that would be used by all the bidders to log in to the portal to submit their bids?
Question 2: If the bidders log in to the portal via common ID, how would CFolders create a separate folder for each bidder to attach their document.
Question 3: Currently I am also not able to open the bid from the bidder side. When I click on the Bid Invitation document link, no action happens. Am I missing some roles?
Any advise on the above queries would be highly appreciated.
Regards
ManojHi,
Question 1: How will the bidders log in to the portal to submit their bids? Would it be with a common ID that would be used by all the bidders to log in to the portal to submit their bids?
Ans: Each Bidder should have seperate user id & pwd
Question 2: If the bidders log in to the portal via common ID, how would CFolders create a separate folder for each bidder to attach their document.
Ans: CFolders directly link with individual user ids.
Question 3: Currently I am also not able to open the bid from the bidder side. When I click on the Bid Invitation document link, no action happens. Am I missing some roles?
Ans: Following role is must in EBP : SAP_EC_BBP_BIDDER in Portal : com.sap.pct.srm.core.ro_supplier & com.sap.pct.srm.gp.ro_bidder

Hi Guys, need help in the following:
1) What does public bid Inviation mean? My understanding is that we will not have to assign any bidders to the bid invitation and it get published on a portal.
2) How do I publish the bid on a portal - I want to publish the bid invitation on Internet where the suppliers can see the opportunity for businees?
3) How does it work - Do we have to generate a PDF using smart form and then put it on the net some how?
4) How will the vendors respond to the Open Bid Invitation as they are not created in the system and do not have login details?
Kind Regards,
Abdul Kadir RajbhoyHi,
Yes you are right.Public Bid Invitation means that any body can bid to the event.If Bidders are involved then it becomes Restricted Bid Invitation.
In Public Bid Invitation,you need to give link to which the intending bidder need to get registered by answering a questionnaire published by your enterprise.Once his registration is approved by the enterprise, he will be issued a userid & Pwd and he will be in a position to submit Bid response.
This requires the setting up of the Supplier Registration scenario.
Thanks & Regards,

Hi,
I'm going to implement SRM in a public company and I would like to know if I had to implement an addon onto SRM to get an specify public business scenario.
Need I something 'out' for SRM?
thanksHi David,
you may want to consider implementing industry solution Procurement for Public Sector, also known as "Government Procurement". This solution is mostly an enhancement of SAP SRM, providing for integration with funds management of ERP, and for automatic capturing and filing of the procurement document, procurement file closing procedures, workload management, mass change operations on contracts, purchase orders, and RFx, mass novations on contracts, post-award processes, the creation of RFx, contract and purchase order documents that contain complex terms and conditions according to regulation, featuring SAP Document Builder and integrating with SAP Records- and Case Management.
Please have a look at the [public sector solution map |http://www.sap.com/industries/publicsector/businessmaps.epx] and get in contact with a field service contact.
Best regards,

Hi All,
Can a accepted bid converted directly into a PO in backend instead of creating first in EBP. If the leading PO is in EBP backend PO cannot be changed. So I want the PO to be created directly in backend through the bid. Is there any process for doing this.
Thanks and regards
Venu
Will reward full points for the solutionHi Venu,
this is possible and the name of the main functionality process is 'sourcing hub' (since release EBP 4.0 i think). Sourcing Hub allows to use the functionalities of the sourcing cockpit without creation of document (Po or Contract) in EBP. Technically the use of sourcing hub means use sourcing cockpit or bid scenario with the classic scenario mode. The creation of the next document in EBP or back-end depends on the configuration of scenario (classic or extended) and on user parameters in organizatational structure.
Is there also a Badi available to the creation of the Contract in backend system instead of local contract because you can not control this in scenario configuration as you can do for the PO.
Hope this can help you.

I am not able to see restricted bid invitations under vendor users.
I have created a restricted bid invitation and assigned couple of vendors to it. I have a user associated with each vendor with SAP_BBP_STAL_BIDDER role. When I release the bid, the vendor users are not able to see the restricted bids. However, I can see the public bid invitations.
Am I missing some configuration? Please let me know
-SurenDear Suren,
It sound like the bidder is not authorized to display the bid inv document, you can try to login from GUI.
Then open the "submit bid" transaction (Tcode BBP_QUOT), after that enter the bid inv number and start, then go to /NSU53, check if there's any authorization failed.After that add the needed authorization ,then try again.

CFolder with Documentum content server
Hello,
We have installed cFolder on WAS which has a RFC connection with ECC6.0 and this ECC6.0 instance uses Documentum content server. I want to understand , is there any impact in terms of document export/import in between content server and cFolder ? Like in normal scenario where cFolder using SAP content server, we use CFE01 and CFI01 transactions in ECC for document import/export in between back-end system and cFolder, in my case can we use the same transactions for document import/export?
Please clear my understanding.
Thanks,
AvinashHi,
Cfolders is basically a functionality in the PLM.
However this can be used in the SRM for the Bidding Scenario.
The functionality deals with the Creation and maintaining a collaboration room in the Public area by the Buyer so that all his bidders can access and allows the Bidders also to create a collaboration room so that the buyer alone can access.
On conversion of a successful bid into the PO the PO will have a link to the Cfolders.
The customizing would be quite simple.
I am sure you will find a document in the SAP Market Place.
Thanks

Help about the last SRM version and interaction with suppliers
Hello, I need the confirm that the last SAP SRM versione is the 7.0. Which are the differences between 5.0 and 7.0? Do you have materials about the interaction with suppliers for bids? Thank you!
DanyHi,
There are a lot of differences between the SRM 5.0 and SRM 7.0.regarding the Bidding Scenario.
Infact SRM 7.0 is released with Public Procurement service(PPS)
The main differences
SRM 5.0 -tender fees payment and EMD (Earnest Money deposit) is thro' Development
SRM 7.0 -Tender fess -Payment can be made in SRM thro'Payment Gateway
- EMD Fees can also be paid in the SRM 7.0 which is Standard Functionality..
There are lot of differnce
Just Wait for a day or two I will send the difference to your Business Id

SRM Category Management - cRoom Integration with cFolders
Can anyone please send me the configuration guide to integrate cRooms (SAP Collaboration Rooms) with cFolders (c Project Suite SAP PLM).
I've got both (SRM-Category Management and PLM-cProjects) the business packages installed on EP and I need to integrate them both.
Suitable points will be rewarded.
Regards
SreenivasFrom ERP using transaction CFE02 you can export the DMS document to cFolders.
These documents can undergo changes in the cFolders.
then via CFI02 you can get back the latest version of the documents from the cFolders into DMS.
In SRM in a bidding scenario, where in you upload all you tendering documents into cFolders which will create a cFolders collaboration in a competitive scenario.
All you docs are put in the public area, then you could create individual areas for you vendors in the same collaboration with atmost security (you can even hide the names of the vendors in the create/changed by columns in the overview tables) .
None of the vendors can see each others information but the public area is visible to all the vendors. Vendors then place their bids in the respective private areas.
You can alternatively use the Portal to create collaboration rooms, which is to upload some docs and download then you would loose the advantage of managing/structuring the bidding process from multiple vendors. Then also the integration aspect with SRM. -
Collaboration not created for bidder
Hi
Currently we are building competitive bidding scenario with cfolders and SRM.
The cfolders CPRXRPM 450_700 (package SAPK-45008INCPRXRPM) has been installed on the SRM server 7 package level (SAPKIBKV05).
Problem statement:
The Bidder is unable to create collaboration folder and following error is displayed on the screen.
u201CError creating collaboration; check user authorizationu201D.
Bidder has following SRM roles in SRM system:
Bidder Role: /SAPSRM/BIDDER
Cfolder User Role: SAP_CFX_USER and
Create Collaborations in the Competitive scenario Role: SAP_CFX_COMP_CREATOR
Am I missing some authorisation here?
I did manage to find OSS note 1375761, however we are at the OSS Note service pack level.
The buyer has created the bid invitation with Cfolder, he has given NONE authorisation to Bidder 1 and Bidder 2 to the Public folder.
The expectation is when the private work area is created by the bidder 1 (which is not happening at the moment due to the above error) while creating bid invitation, the content of the public area will be copied to the bidder 1 work area with restrcted authorisation to other bidders, so that bidder 2 will not be able to see bidder 1 work area. Similarly bidder 1 will not be able to see bidder 2 work area.
Is this the right process to configure the competitive business scenario? Please advice!!
I also tried creating 2 manual private work areas for each bidder and then assign the bidder user ID with admin roles respectively. Still we are getting the above error and bidder is unable to create the bid response.
Is it a bug in the system? or am I missing authorisation step?
Please advice!!
Regards,
Sandeep ParabAshwin,
Unfortunately the program BCFOLDER20_COL_CREATE is not stopping at the breakpoint.
I did investigate further with cfolder authorization.
If I give the bidder the administrator rights to the public area then the system automatically creates the private area while creating bid invitation. By doing this the system automatically give access to other bidders private area, which we do not want.
I really would like to understand how to control the folder administration role such that the system creates the private area while creating bid invitation also at the same time the bidders are not able to access each others private area?
Is it possible with standard competitive functionality or we need to do enhancement to control the authorization?
This is a very common scenario, I am sure someone might have archived this before. Kindly advice!!
Regards,

Hey everyone, just came across this forum looks quite good so I'll give it a go smile.gif
Just working through a book called 'Objects First with Java' and I'm stuck on exercise 4.31.
This is about a small auction program that has 4 classes - auction, bid, lot and person.
Here's the code:
Auction:
import java.util.ArrayList;
import java.util.Iterator;
* A simple model of an auction.
* The auction maintains a list of lots of arbitrary length.

public void bidFor(int lotNumber, Person bidder, long value)
selectedLot = getLot(lotNumber);
if(selectedLot != null) {
boolean successful = selectedLot.bidFor(new Bid(bidder, value));
if(successful) {
System.out.println("The bid for lot number " +
lotNumber + " was successful.");
else {
// Report which bid is higher.
Bid highestBid = selectedLot.getHighestBid();
System.out.println("Lot number: " + lotNumber +
" already has a bid of: " +
highestBid.getValue());
* Return the lot with the given number. Return null

* @param lotNumber The number of the lot to return.
public Lot getLot(int lotNumber){
if((lotNumber >= 1) && (lotNumber < nextLotNumber)) {
// The number seems to be reasonable.
Lot selectedLot = lots.get(lotNumber - 1);
// Include a confidence check to be sure we have the
// right lot.
if(selectedLot.getNumber() != lotNumber) {
System.out.println("Internal error: Lot number " +
selectedLot.getNumber() +
" was returned instead of " +
lotNumber);
// Don't return an invalid lot.
selectedLot = null;
return selectedLot;
else {
System.out.println("Lot number: " + lotNumber +
" does not exist.");
return null;
public void close() {

String personName=person.getName();
String number = "" + lot.getNumber();
if(lot.getHighestBid() == null) {
System.out.println(number + ": " + lot.getDescription()+" has *not* been sold");
else {
System.out.println(lot.getDescription()+" has been sold to " );
// Creates a new array list and stores all unsold items into notSold.
// Returns all items in the new list.
/* public ArrayList<Lot> getUnsold;
ArrayList<String> notSold;
Integer numberList = 1;
notSold = new ArrayList<String>(); // Creates new array
for(Lot lot : lots){ // Although it compiles, when I create an auction object
// it returns 'null pointer exception' here, any suggestions?
if(lot.getHighestBid() == null)
notSold.add(lot.getDescription());
for(String unsold : notSold){
System.out.println(numberList + ": " + unsold);
System.out.println();
numberList++;
} There are a few random things in there, just from me mucking around in other exercises.

}Question: Rewrite getLot so that it does not rely on a lot with a particular number being stored at index (number-1) in the collection. For instance, if lot number 2 has been removed, then lot number 3 will have been moved from index 2 to index 1, and all higher lot numbers will also have been moved by one index position. You may assume that lots are always stored in increasing order of their lot number.
So I know it's talking about an arraylist but I can't think how to implement it, I have tried a number of ways but can't seem to get my head round it. After I couldn't work out how to rewrite just the getLot I started spreading out and trying to add new arraylists in different classes and calling them but it ultimately just failed so now I was just wanting to get some ideas from people.@ The OP....
Word of advice. Posting pages of code that are provided for YOU are not gonna be welcome on these forums. You can however take snippets of code and post them here and in turn ask a more precise question. For example....

if I try to say
LotObjectName.getHighestBid, I get aDear EsoralTrebor,
Thank you very much for an enlightening explanation.
I had never tried to chain methods together before but it works !
anObject.methodOfTheObjectClassThatReturnsAnObjectOfAnotherClass.
methodOfTheObjectClassThatWasReturned();
my output correctly states:
The highest bid for the bicycle is 1510
The highest bid for the lamp is 510
The highest bid for the trailer is 900460
Thank you !
Stan
ps tomorrow I need to study the showLots() method in the Auction class
to figure out why that method is saying "No Bid" to everything
Have a Good Thanksgiving ! -
hello
can anyone help me with this problem
atm i'm making a project which uses EJBs (with JPA) and some fields in the EJBs get auto generated when persisting an EJB entity to the database
Writing to the database and reading out of it works perfectly, but when i persist a brand new entity to the table, i don't receive the brand new generated ID
(ID is a primary key in the table)
is there any way to update the persisted entity right after persisting it to the database ? so that my entity, which got persisted, gets his ID injected?
this is my code for inserting a new entity into the database:
@Transactional
public class JPAScenarioDAO implements ScenarioDAO{

public void createScenario(Scenario scenario){
entityManager.persist(scenario); // <-- help?
public void updateScenario(Scenario scenario){
entityManager.merge(scenario);
public void removeScenario(Scenario scenario){
entityManager.remove(scenario);
}The scenario is an EJB that i generated from a table

}I've seen this happen.
Changing it to
public Scenario createScenario(Scenario scenario){
entityManager.persist(scenario); // <-- help?
return scenario;
}(and using the returned value) for some reason worked.
Not quite sure yet why, I'll have to do some research to figure out exactly what happens.
