Since the append function was removed from the r12 upload process, Datalink must be used when a table needs appending, not overwritten. Since my data is too large to append all at once, with one excel file append, I was trying to append multiple times in one "check out" and "check in" process. However, Datalink seems to only keep the append of the last run for that connector. Is that correct? Am I unable to have Datalink append an already checked out document with more append loads? Hopefully, this makes sense to someone. If there's a document that I should read, please let me know. This won't happen often, but understanding would help me know how to prepare/plan. Thanks in advance.
