Can't submit multiple products in a single request to ChangeCatalogEntry web service (Websphere Commerce) - websphere

Question

Using Websphere Commerce V7, FP6, FEP5.
I am attempting to do an update to our catalog using the ChangeCatalogEntry web service. I am able to update a single product just fine. My problem is that any additional CatalogEntry nodes are completely ignored. It appears to process only the first CatalogEntry node it finds. I am using SoapUI to submit the requests. Here is a sample that I am attempting to submit. In this example part number p_MAT153 is updated but p_MAT203 and p_MAT185 are not. Is the webservice designed to only update a single product per message?

Answer 1

The answer turned out to be in the oa:ActionCriteria node. I needed a matching node for every instance of CatalogEntry.
<oa:ActionCriteria>
<oa:ActionExpression actionCode="Change" expressionLanguage="_wcf:XPath">/CatalogEntry[1]/Description[1]</oa:ActionExpression>
</oa:ActionCriteria>
<oa:ActionCriteria>
<oa:ActionExpression actionCode="Change" expressionLanguage="_wcf:XPath">/CatalogEntry[2]/Description[1]</oa:ActionExpression>
</oa:ActionCriteria>
<oa:ActionCriteria>
<oa:ActionExpression actionCode="Change" expressionLanguage="_wcf:XPath">/CatalogEntry[3]/Description[1]</oa:ActionExpression>
</oa:ActionCriteria>

Answer 2

Just to add to that: You can run several action son the same data object, to for instance create attributes , remove attributes, set SEO data etc. However, this can confuse the graph object if you don't sort the actions in the order of Add, Change and Delete.
