Having searched these forums for some time now, have decided to post.
Used remote BM function at start of a levelling traverse, unfortunately used wrong target height in error. Went into raw data and edited to correct height.
Cannot seem to re-reduce file to get corrected levels. Yes edit appears to have been saved and note about time and original info. appears in raw file.
If I am understanding the proceedure correctly, I now go into "process No Adjust" and this should update the coord file RLs. etc. but there is no change!
I must have missed something somewhere. What's the point of editing the raw data if you cannot effect changes to the reduction. Downloading the raw data again to Liscad and reducing also produces no change in final levels.
