Access Auction collection in ESO 5.1

[Former Member]

Hi,

I am using ESO 5.1 and I need a script to create an auction from external data (XML) and vice versa: read auction data and create XML from it. For the second task, I'd like to use a Toolbar script. This is always called on Auctions (doc is an Auction).

I have the following problem: I can reach the "single" fields of the auction but I can not reach the collection members.

I use the following code:

1st version - lst is always null

CollectionIfc lst = doc.getExtensionCollection("COLLN:1:802"); // should contain auction line items

2nd version - lst is not null but contain only nulls

StringBuffer str = new StringBuffer();

CollectionIfc lst = doc.getCollectionMetadata("COLLN:1:802").get(doc); // should contain auction line items

for(int i = 0; i < lst.size(); i++) {

str.append("Line item:" + lst.get(i)); // lst.get(i) is always null

}

I tried all class collection names found in documentation - with no result.

Could you write me how to reach collection members?

Hi,

Standard collections can be accessed by their respective/specific accessor methods(e.g getLineItems()). Don't think the generic accessor methods would work for standard collections .

E.g in case of RFX/Contract you would have a getLineItems() method. It looks like Auction doesn't have an API to enable accesing the line item collection. You may have to request SAP for that.

In general, if you have access to a collection, all you have to do is get the iteratort. e.g. getLineItems.iterator() and use the hasNext(), next() methods to get its members

Hi Baski,

thanks for your answer.

According to the Class documentation, Auction class contains - among others - the following class collections:

COLLN:1:802 - subordinate - contains doc.auction.lineitems

COLLN:3:810 - associative - containing auction.bidders

etc.

So you mean, there is NO way to read and set these collections using API calls?

thanks again,

Hi,

You are correct. As far as I know, If an API access is not provided to access a collection, you cannot access them. You may have to request SAP for that explaining your case.

Thanks,
