Change Pointers

Former Member — Wed, 13 Jun 2007 20:08:43 GMT

Hello all,

I have to download a file containing WO#, WO type, status and Tech ID # into an XML file when a Work Order (WO) is created using IW31 tcode. I looked for User exits and tried using IWO10009 and IWO10012, but found that work order number is not assigned by the time it reaches these exits.

During this reseach I found that there is a concept called change pointers. I have no idea how to use them I was wondering if it fits my requirement and needs any coding and if yes can anyone help me code that?

please let me know.

Note: I read a couple of threads in the forums and got a basic idea what change pointers are but I need help in using them.

Thanks in advance for your help

Hello Venky,

Welcome to SDN.

Whenever a WO is created or changed a change document or a change pointer is created with insert/update indicator. I believe the object class is ORDER (but I am not sure...please investigate) for WO. Since you need to download the newly created ones, you need to develop a report which reads all these change pointers and you will get the order number from the change pointer table (field I think it is OBJECTID/CDOBJID).

The tables for change documents is CDHDR and CDPOS

Change pointers BDCP and BDCPV

Hope it helps.

Rgds,

Naren

Hi,

Yes, after the Work Order gets created then only you will get the Order number. In order to download the information to a file, then you can write a simple report program which will download all Work Orders into a local file. for this you have to write a Select statement on AUFK table by passing your Username i.e, sy-uname, Creation Date etc, Order type etc to the Where clause. you will get all Orders created for the selection criteria you used.

thanks,

thanks Naren, Ars and srinivas for the replies.

Srinivas,

the client doesnot want to run any program or schedule it for the file download. All they want is, when a work order is created a file needs to be downloaded automatically. This is the reason I looked for user exits initially.

Can anyone provide me a sample code for change pointers? I mean how to find a change pointer and use it in coding.

Thanks again..

At tis point I owuld suggest you to kepp a break point in the exit and create a WO. The WO data should be in <b>CAUFV</b> structure. I guess you can write the code in the exit and download the file.

I am ot sure of which exit would work good.

Hope it helps.

shreekanth,

I debugged most of the code and searched for user exits while creating an order...I saw that there are user exits before the WO number s created.

Thanks,

Please try to do this.

Before you save activate debugger. /h and then hit save.

Once you enter the debug mode please look for structure CAUFV. Initially it will be blank but at a later stage it will be populated with data. Check the program where the data is populated.
