Curtis,
If I understand you're requirement correctly, you want to "Send all changed items on the ORDCHG. In addition to these, you want the item long text sent for all the items that haven't been changed".
If this is true, I would do it in one of the following ways:
1. Send all the data (like ORDERS) on an ORDCHG IDOC along with long texts and have the vendor compare each item and see which ones have changed. --> I know this is not a preferred option for all the clients but I have done this at one of the client who had the muscle to have his vendors comply to his needs.
2. Change exit: EXIT_SAPLEINM_001. Pick up all the materials listed in UEKPO, go back to EKPO and get the remaining for that PO and populate long text field which would go into E1EDPT1/T2 segment and update those relevant fields in UEKPO and save it. The next form would automatically pick up these and fill up the IDOC. This way, you'll see E1EDP01 (and the segments beneath it) for all the materials but you just populate E1EDPT1/T2 and rest are blank. I might have oversimplified it because I didn't go in and check how the program flow would work but I'm positive this is a good way to start. The reason I would like to change EXIT_SAPLEINM_001 is that this is the place where the actual IDOC filling didn't start yet and all you have to do is feed into UEKPO so that the next perform will take care of the rest.
Let me know if this works out for you. If you went through any alternative way then do educate me back
Just a thought: You're question is different to the original thread here (although related). We're hijacking this thread. So I think it'll be better if you put it in a new one.
