Hello people, I am completely new to Talend and I'm researching of Talend can help me with my 'problem'. So here's the deal. I have these excel files with data I need to send to a webservice. This wasn't that hard to achieve and I managed to get things working with a tFileInputExcel --> tXMLMap --> tESBConsumer setup. But here's the real problem, and I wonder if Talend can help me with it; The excel file basically looks like this: customer_id product_number product_name customer_name 11 12345 PC SUPPORT John Smith 11 56789 Macbook Pro John Smith 12 12345 PC SUPPORT Adam Johanssen 12 66554 ACER laptop Adam Johanssen 13 12346 PC/Tablet SUPPORT Sandra Bullet 14 56788 Macbook Air Peter Sandman What basically happens is a customer buys a hardware product like a PC or laptop, and buys some kind of service product for that PC. With my current setup, my job just parses over the whole .xls file row by row and maps it. But what I need is to somehow combine rows into a single 'object' based on the customer_id, so that the hardware product and service product a customer bought, belong to the same row/object. So what needs to happen is: -check if every service product has a hardware product (are there duplicate customer_id's?) -if yes, combine/map those products so it becomes something like this customer_id service_product_number service_product_name customer_name hardware_product_number hardware_product 11 12345 PC SUPPORT John Smith 56789 Macbook Pro -if not, throw a fault/log it/ignore it -send the combined rows/object to a webservice If someone could at least give me a tip on what components I could use for this (if there are any) it would be much appreciated.
Gezz, I do not understand your dataset from the description you gave. You mention software product - there is none shown on your example The components you have listed are correct. you can have a look at 'tSchemaComplianceCheck' to validate unique IDs each row is in fact loaded into a single 'object' (java); please have a look at the 'CODE' tab in your job. were these suggestions helpful?
Hello Nicolas, I made a mistake. It should have been 'service product' instead of software product. (i changed it in my original post). What I meant is that a Customer (John Smith) buys a product (Macbook) and also buys a 'service' product (PC SUPPORT) to go along with his brand new Macbook. But these products John has bought (Macbook and PC SUPPORT) are on separate rows in the .xls file. What i want is that both rows belonging to that Customer (John Smith with ID 11) become a single row/object so I can send that combined data to a webservice. I hope this made it a bit more clear, I will look into tSchemaComplianceCheck, thanks!
